Cynthia L. Walker

Thank you, Chris, and good morning, everyone. Thank you for taking the time to join us on our call today. During my comments, I'll reference several slides in the conference call materials that, as Chris mentioned, are available on our website.

Overall, in the second quarter, we continued the trend of solid execution seen in the first quarter. We produced 772,000 barrels per day, essentially in line with our expectation, adjusting for certain events during the quarter. Our operating cost and capital efficiency programs remain on track. We had core earnings of $1.3 billion, or $1.58 per diluted share.

For the 6 months of 2013, we generated $6.4 billion of cash flow from operations before changes in working capital, and we ended the quarter with $3.1 billion of cash on our balance sheet.

If you turn to Slide 3, you'll see a summary of our earnings for the quarter. As I just mentioned, core income was slightly under $1.3 billion, or $1.58 per diluted share. Compared to the first quarter of 2013, the current quarter reflected improved oil and gas results, driven by higher oil volumes, offset by lower earnings in the marketing and trading businesses, largely due to commodity price movements during the quarter, and higher equity compensation expense resulting from an improved stock price.

I'll now discuss the segment performance for the oil and gas business and begin with earnings on Slide 4. Oil and gas earnings for the second quarter of 2013 were $2.1 billion. And as you can see, this was an increase over both the first quarter of 2013 and the second quarter of 2012. On a sequential quarter-over-quarter basis, improvements came from higher oil volumes, in particular, in the Middle East and North Africa business, following the resumption of production after facility turnarounds in Qatar and Dolphin. We also experienced better realized domestic oil and gas prices, although they were offset by lower realized international oil prices. Improvement in domestic realized prices is mainly attributable to the easing of oversupply in the Permian. This significantly improved differentials for our Permian oil production. There was also a modest increase in exploration expense.

Moving to Slide 5, you'll see a breakdown of production changes during the quarter. As I mentioned, production was 772,000 barrels per day. This is an increase of 9,000 barrels over the first quarter and 6,000 barrels over the year-ago quarter. On a sequential quarterly basis, these results reflect the resumption of production in Qatar and Dolphin and growth in our California business as a result of our drilling program. Elsewhere domestically, we saw the impact of natural decline due to our reduced natural gas drilling activity. Also reflected are the impacts of weather and planned gas plant turnarounds in our Permian business as well as insurgent activity in Colombia. These events combined to reduce production by about 7,000 barrels per day during the quarter.

Also, on a year-over-year basis, full cost recovery and other adjustments under our production sharing and similar contracts reduced production by about 8,000 barrels per day. The impact on a sequential quarterly basis was not significant.

Overall, while there were a number of events that impacted production this quarter, we see the underlying business is performing essentially as we expected.

If you turn to Slide 6, I'll discuss our domestic production in a bit more detail. Our domestic production was 470,000 barrels per day, a decrease of 8,000 barrels per day from the first quarter of 2013, driven by the factors illustrated on the previous slide. And this was an increase of 8,000 barrels per day from the second quarter of 2012.

Focusing on our commodity composition, our oil production was essentially flat versus the first quarter, adjusting for the effects of the severe weather in the Permian. Our natural gas and NGL volumes were 5,000 barrels per day lower than the first quarter, excluding the impact of planned gas plant turnarounds. This reduction primarily reflects natural decline in the Mid-Continent due to lower drilling activity and third-party processing bottlenecks in the Permian.

In total, sales volumes were 764,000 barrels per day in the second quarter of 2013 compared to 746,000 barrels per day in the first quarter. Middle East/North Africa sales volumes were 31,000 barrels per day higher, mostly due to the timing of liftings as well as the effects of the first quarter maintenance turnarounds.

Our overall sales volumes were lower than production volumes during the quarter due to the timing of liftings. The pickup in insurgent activity in Colombia caused a delay in 2 large liftings scheduled around the end of June. In total, delayed liftings reduced the second quarter pretax earnings by approximately $75 million, or about $0.06 per diluted share on an after-tax basis.

We expect the third quarter liftings in Colombia to be at their normalized level, barring any pickup in insurgent activity in the third quarter.

Our realized prices for the quarter and the comparison to benchmark prices are summarized on Slide 7. Compared to the first quarter, our worldwide crude oil realized price was almost flat. As you can see, the reduction in Brent was offset by improved realizations for our Permian production.

We continued to experience weakness in NGL pricing domestically, which contributed to a 4% decrease in worldwide NGL realized prices, while domestic natural gas realized prices experienced a 24% increase, driven by improvement in the benchmark. You'll also note that we updated our price sensitivities.

Next, I will cover production costs on Slide 8. Oil and gas production costs were $13.40 per barrel in the second quarter. For the first 6 months of 2013, production costs were $13.66 per barrel compared to $14.99 per barrel for the full year of 2012. The largest improvement was seen in our domestic operations, where production costs were $3.26 per barrel lower in the first month -- first 6 months of 2013 from the full year of 2012. This represents annualized cost savings of over $500 million, exceeding our previously stated goals.

International production costs have remained fairly consistent with 2012 levels, excluding the impact of facility turnarounds in Qatar and Dolphin, which affected the first quarter.

Taxes other than on income, which generally relate to product prices, were $2.66 per barrel for the first 6 months of 2013 compared with $2.39 per barrel for the full year of 2012.

Second quarter exploration expense was $78 million. We expect third quarter exploration expense to be about $90 million for seismic and drilling in our exploration programs.

Now turning to the chemical segment core earnings on Slide 9. Second quarter earnings were $15 million lower than the first quarter. This is primarily the result of lower caustic soda export volumes due to weak economic conditions in Europe, slowing demand in Asia and reduced demand for alumina in South America. We expect third quarter 2013 earnings to improve to approximately $170 million, benefiting from the higher seasonal demand and continued strong PPC sales into construction markets.

On Slide 10 is a summary of the midstream segment earnings. They were $48 million for the second quarter of 2013 compared to $215 million in the first quarter of 2013 and $77 million in the second quarter of 2012. The sequential quarterly and year-over-year decrease in earnings resulted mainly from lower marketing and trading performance, driven by commodity price movements during the quarter.

Our worldwide effective tax rate on core income was 41% for the second quarter of 2013, and we would expect that our combined worldwide tax rate in the third quarter will remain at about the 41% level.

And finally, on Slide 11, I'll discuss our year-to-date cash flow performance. For the first 6 months, we generated $6.4 billion of cash flow from operations before changes in working capital. This amount includes an approximate $380 million cash inflow from the collection of a tax receivable. Working capital changes decreased our cash flow from operations by about $200 million, to $6.4 billion.

Net capital expenditures for the first 6 months of 2013 were $4.2 billion, of which $2.2 billion was spent in the second quarter. We generated approximately $270 million with the sale of our investment in Carbocloro in the quarter, and we used $225 million for acquisitions of domestic oil and gas assets, of which about $125 million was during the quarter.

After paying dividends and other net outflows, our cash balance was about $3.1 billion as of June 30. Our debt balance remains unchanged and our debt-to-capitalization ratio was 15% at the end of the quarter.

Our annualized return on equity for the first 6 months of 2013 was 13%, and our return on capital employed was 11%.

I'll now turn the call over to Steve Chazen to discuss other aspects of our operations and provide some additional guidance for the third quarter.

Stephen I. Chazen

Thank you, Cynthia. Occidental's domestic oil and gas segment continued to execute in our liquids production growth strategy. Our first half domestic oil production of 262,000 barrels a day was an increase of about 7% from the first half of 2012 production of 246,000 barrels a day. Second quarter domestic production of 470,000 barrel equivalents per day consisted of 338,000 barrels of liquids and 792 million cubic feet of gas, a decrease of about 8,000 barrel equivalents per day compared to the first quarter.

Liquids production decreased slightly due to planned gas maintenance turnarounds in the Permian, which impacted natural gas liquids production. Plant turnarounds also impacted our gas production, which coupled with lower drilling on gas properties. Natural decline comprised the bulk of the total domestic production decline. A number of severe storms affecting the Permian region also lowered our domestic production. Second quarter domestic production was generally in line with our expectations, except for the impact of storms.

We're executing a focused drilling program in our core areas. And to date, we are running ahead of our full year objectives to improve domestic operational and capital efficiencies. For example, we have reduced our domestic well cost by 21% and our operating cost by about 19% relative to 2012. This is ahead of our previously stated targets of 15% well cost improvement and total oil and gas operating cost below $14 a barrel for 2013. We believe we can sustain the benefits realized to date, achieve additional savings in our drilling costs and reach our 2011 operating cost levels over time, without a loss in production or sacrificing safety. The purpose of these initiatives is to improve our return on capital.

I will now turn the discussion over to Vicki Hollub, our Executive Vice President in charge of our California operations. Prior to her current role, she ran our Permian enhanced oil recovery, or CO2, business. She will provide details of our strategies for the next couple of years, considering the current California operating environment. She will also discuss the results of our capital and operational efficiency improvement programs. Vicki?

Vicki Hollub

Thank you, Steve. We are a California company, and we are committed to being a responsible partner in the numerous communities in which we operate, spanning from north of Sacramento to south of Long Beach. We're the state's largest producer of natural gas and the largest oil and gas producer on a gross operated barrels of oil equivalent basis. We provide locally sourced energy to help Californians cool their homes and drive their cars. Since 2010, we have created 3,000 new jobs, invested over $8.5 billion in the state and paid $900 million in state and local taxes. We're also the largest oil and gas mineral acreage holder in North California, with more than 2.1 million net acres in some of the most prolific hydrocarbon-producing areas of the state. Our vast acreage position has diverse geologic characteristics and numerous reservoir targets, providing us with development opportunities that range from conventional to steam and waterfloods and unconventional. We plan to continue investing in providing energy for the state for decades to come.

This morning, I would like to give you a look at the progress we've made in California this year. When we started the year, our overall objective was to position our portfolio for a long-term profitable growth while achieving immediate wins to have a successful year. Our specific goals were: deliver a predictable outcome for this year, given the constraints of working in California; advance projects with solid returns, low execution risk and long-term growth; reduce our drilling and completion cost to improve our finding and development cost and our project economics; reduce our operating costs without affecting production to improve our current earnings and free cash flow; build a growing and highly predictable lower-declined base of production; test out various exploration development concepts both from a cost improvement and execution predictability perspective.

In 2012, we restructured our business units to create teams organized around the unique characteristics of each of our asset groups, resulting in a fifth business unit dedicated to managing our heavy oil properties. This heavy oil team has added the expertise necessary to accelerate the development of our existing steam floods and to evaluate new opportunities.

In addition, we created 3 technical teams to better manage the complex geology of the reservoirs in California. One team is dedicated to the design of new waterfloods or the optimization of existing floods. Another will look exclusively at the aggressive application of the EOR technologies, including steam floods, where they are technically and economically feasible. The third team will focus on unconventional development opportunities to optimize recoveries from the Monterey and other key shale plays in California.

We believe this structure gives us the ability to grow our California operations more efficiently, maximize the benefits from the improvement in operating and capital costs that we've already achieved and drive additional improvements in our cost structure.

As you know, we're engaged in a companywide effort to reduce our operating cost and improve capital efficiency in order to improve our returns. In California, we have significantly reduced operating as well as drilling costs, exceeding our targets. And we expect to save at least $175 million this year in operating costs through these efforts.

On the last call, we provided a thorough breakdown of the efforts being made in all domestic assets, and we have achieved similar success in California.

We've reduced our overall operating expenses by $3.50 per BOE, from $23.20 in 2012 to an expected average of $19.70 for all of 2013. Almost half of these reductions have been in well servicing as a result of high-grading our well service rigs and eliminating less efficient ones, better planning and scheduling of jobs, reducing lower value-adding jobs and adding Oxy supervision through reduction of contract wellsite operators. Improvements and innovations in service operations account for another 35% of the reduction. Activities contributing to these reductions include optimization of the use of chemicals, improved water handling, fuel and power cost reductions and lower rental equipment use.

In capital efficiency, we've also improved by about 15% year-to-date compared to the full year 2012. This success was achieved by focusing on 4 key elements of our capital program. First, we have locked in our drilling programs for a minimum of 2 months and in some areas up to 9 months. This reduced our nonproductive times associated with rig moves and third-party services and helped to reduce our equipment rental cost.

Secondly, we've revised well designs to more appropriately fit the wellbore characteristics and production expectations for each well.

Third, we have optimized drilling equipment and fluids to reduce the time required to drill wells.

Finally, we have improved our contracting strategies to incentivize our service providers to optimize overall performance through integrated service applications while reducing unit costs. In many instances, such as in the Rose Field, we've been able to generate significant savings through the application of one or more of these concepts I just mentioned and then apply those same concepts to other wells across the state, which has allowed us to duplicate the savings.

Many innovative ideas are being generated and implemented by our California teams across the state. As we have stated several times before, many of these ideas are being generated by our people at the grassroots level, which tend to generate individually modest cost improvements that accumulate to significant amounts across all of our projects as successes are replicated. Our people have embraced this effort and are committed to improve operations of our assets at every level by reducing cost and continuing to improve safety everywhere we operate. While the results we have seen so far are very positive and impressive, we believe that we can achieve even more improvements in both operating and capital costs going forward.

After reviewing our California assets as a whole and taking into consideration market conditions, we adjusted our capital strategy at the start of the year to allocate a higher percentage of our annual budget to lower-declined projects project, such as our waterfloods and steam floods. For this year, we plan to spend almost 65% of our capital program on water and steam floods, or approximately $625 million on waterfloods, $370 million on steam floods, out of the total $1.5 billion capital.

We will spend about 25% of the capital on unconventional projects and the remaining 10% on primary drilling projects. Further, given the market conditions, we have increased a portion of our capital on oil and gas liquids development, which represent about 99% of our California capital for this year.

California has unique opportunities, with diverse and complex geology. This geologic complexity leads to a broad spectrum of hydrocarbon fields and reservoir types. The depth, quality and drive mechanisms of the reservoirs vary across many of the producing basins and within individual basins as well. Those varied characteristics, along with product prices, costs and returns, determine the mix of the type of projects to be included in our program each year.

The significant strides we have made in reducing our capital and operating cost that I've described have given us the flexibility to include a large number of potential projects in our development pipeline. For example, depending on the type of project and location, our drilling costs in California, including completion and hook-up costs, range from $250,000 to $7 million, with expected ultimate recoveries of 30,000 BOE to 550,000 BOE per well, getting us a wide range of opportunities and variability.

Given our diverse portfolio of opportunities in California, we have sufficient inventory to sustain the strategy in the future for at least another 5 years and probably even for 10 years or more, while adjusting the liquids versus gas mix as conditions warrant. We believe this approach will provide the best opportunity for growth of the California operations and make it a significant growth engine for Oxy.

Now I would like to share some highlights about each of those project types, beginning with waterfloods. Waterfloods are among our core competencies. We have several new waterflood projects in progress this year in various stages, from screening to implementation, in addition to a number of floods, where we are engaged in redevelopment, expansion or optimization activities. We will spend most of our waterflood capital to further optimize our most developed project, the giant Wilmington Field, where our Long Beach business unit is continuing to have success in reserves recovery. Wilmington is a long-standing waterflood, where the keys to redevelopment success are effective reservoir characterization, performance surveillance, reservoir modeling and advances in directional drilling technology. This year, we will drill 135 new wells, including 35 horizontal wells, targeting attic oil and fault-isolated zones within this multi-play reservoir.

In Wilmington, we have used a combination of vertical and horizontal wells depending on the location. Vertical or slant wells can be cost effective in certain locations. And in others, horizontal wells are drilled to target specific sand intervals within the larger waterflood zone, which have not been effectively swept by the injected water. These wells have an average initial production, or IP, rates of over 3x higher than similar vertical wells at a cost of just 20% more than the comparable wells.

We believe there's still significant potential to be realized in the Wilmington field. For example, since we acquired this asset in 2000, proven reserves have steadily grown. In fact, year-end 2012, proved reserves remained slightly higher than 2000 levels despite 12 years of production, resulting in more than a twofold proved reserve increase during this period. We currently have an inventory of over 1,000 future well locations in the Wilmington field. We believe that a successful development program focused on these wells over the next 7 years will deliver reserves of up to 100 million BOE.

Just south of Wilmington, we are starting the redevelopment of the Huntington Beach Field with 2 new fit-for-purpose rigs, an onshore rig, which has an enclosure specifically designed for drilling in urban areas, and an offshore rig. We expect both of those rigs to arrive and start drilling towards the end of the year. So far, we have identified 128 well locations to drill, which will take 4 to 5 years using the 2 rigs we currently have committed. We expect to add more well locations as we learn more through our reservoir modeling and surveillances, as we have done in the analog Wilmington Field. We believe that we can increase our production from this field by 10,000 BOE per day and develop reserves of at least 50 million BOE.

Another significant project for us is the waterflood expansion at Buena Vista Field, where we expect to drill more than 150 wells over the next 5 years. We believe we can increase the Buena Vista production by 4,000 BOE per day and deliver reserves of 28 million BOE.

In addition, our Vintage unit, which is the team that manages our San Joaquin Valley and Ventura County waterfloods, gas properties in the Sacramento Valley and unconventional projects outside of Elk Hills, they have several waterfloods in the pilot phase this year, several under evaluation for redevelopment and a long list of potential projects going through the waterflood screening process. In total, we will spend around 40% of our 2013 California capital on waterflood projects that are expected to generate returns, exceeding 20% on average.

In addition to waterfloods, our steam flood activities have also been a sizable focus for us this year. Our steam floods in California are highly profitable, taking advantage of the gas versus oil price spread, allowing us to use cheap gas to generate steam, which is then used to inject into the reservoir to produce oil. We believe these projects can deliver attractive returns with the combination of gas prices as high as $6 per Mcf and oil prices as low as $80 per barrel. Typical rates of return for these projects are expected to be 25% or better.

The 2 largest steam flood projects for 2013 are in the Kern Front and Lost Hills fields, being managed by our newly formed heavy oil team. These 2 fields contain over 1 billion barrels of oil, original oil in place, on a combined basis, with an estimated 870 million barrels remaining in place. We're in the process of expanding our steam generation capacity in both fields, and these projects are progressing as expected. We have drilled 100 wells in these 2 areas year-to-date. And with the recent addition of 2 rigs, we expect to drill an additional 200 wells in the second half of this year.

As a result of our activity in these projects, production from our heavy oil business unit is expected to increase by around 3,000 BOE per day by the end of this year over our 2013 entry rate. Full development of these steam floods is a multi-year endeavor, and we believe that over time, we can increase our heavy of production by 15 BOE per day, developing reserves of 120 million BOE.

We're also preparing to pilot 2 smaller steam floods in Oxnard and the Midway Sunset Area by the beginning of next year. With the success of these projects, we expect to be able to develop an additional 45 million BOE of reserves.

Our total steam flood spending will constitute about 25% of our total California capital in 2013. Over the next 5 years, we expect to drill 1,500 steam flood wells.

As we shift capital to greater water and steam flood opportunities, we expect a lag of about 6 to 9 months before we see sustained production growth, as the flow of new projects reaches a steady level. We're in this transition period but are now beginning to see the initial phases of growth from these projects.

In addition to shale plays, our unconventional opportunities include those reservoirs that have low permeability and require special recovery processes to flow. Currently, about 1/3 of our California production is from unconventional reservoirs. This year, we plan to drill more than 70 unconventional wells. We have more than 1 million prospective acres for unconventional resources, which we believe contain up to 7 billion BOE of recoverable reserves. We have drilled approximately 1,300 unconventional wells in California since 1998. More than 1,000 of these have been in and around Elk Hills, including the Monterey and other key shale plays. Our current plan includes 53 unconventional wells from multiple shale plays around Elk Hills, with varying costs and expected performance depending on the well's location and its particular structure. All of these 53 wells are a part of continuing development programs that are delivering better than 20% rate of return. Our ongoing program around Elk Hills is expected to increase our ultimate recovery by about 150 million BOE.

An example of unconventional opportunities we are pursuing outside of Elk Hills includes drilling and development at the Rose Field. We purchased this field in late 2009 and drilled 1 appraisal well in 2011, 8 development wells in 2012 and 6 horizontal wells this year, with plans to continue drilling. Results have been very good, with average IP rates exceeding our expectations and estimated ultimate recoveries of approximately 155,000 BOE per well on average. We believe our returns from this field will be around 25% over the course of the development program. We also plan to drill additional unconventional wells in South Belridge and the Buena Vista areas this year. Success in these areas could ultimately provide more than 100 well locations and up to 35 million BOE in net reserves.

A discussion of the future potential of California will not be complete without a separate discussion of Elk Hills, which we acquired in 1998. At that time, Elk Hills had gross proved reserves of 545 million BOE, 424.5 million BOE net to Oxy. Now cumulative production since our acquisition in 1998, combined with our current proved reserves, is almost double the proved reserves for Elk Hills at the time of the acquisition, which shows that we continue to generate ways to get more out of these reservoirs, and we're not done with Elk Hills.

In recent years, our growth in California has come from projects outside of Elk Hills. This is due to our big challenge at Elk Hills, where the underlying base decline without any capital expenditures would be around 25%. However, we are now looking at additional opportunities, which we expect will further increase the reserves at Elk Hills and help to mitigate the decline rate, possibly reducing it by as much as 50%. These opportunities include waterfloods, steam floods, as well as potential polymer and CO2 floods that could be implemented over the next 3 to 10 years. These significant operating and capital efficiency improvements made by the Elk Hills team will improve the profitability of these waterfloods and the EOR opportunities.

I would also like to point out that our plant operations team at Elk Hills has done a great job of optimizing runtime and reliability from our new cryogenic gas plant. Currently, the team is operating the plant at greater than 90% uptime, and they have extracted record volumes of NGLs from the gas streams this year.

Elk Hills still has more than 900 million BOE of remaining reserves and resources that can be recovered through waterflooding and current proven EOR technologies, in which we have considerable expertise, so we're going to continue our development efforts at Elk Hills.

Our California exploration program has delivered solid results over the last 5 years since we ramped it up. From 2007 through 2012, we have drilled over 100 exploration wells across the California basins in both conventional and unconventional plays. A full 2/3 of our wells have found hydrocarbons, and a large portion of these successful wells resulted in commercial production. We have been busy over the last few years acquiring 3D seismic over a significant portion of our acreage, and this has contributed to our high rate of success. Access to this new seismic data and working closely with our operating groups has allowed our exploration staff to build creative and innovative programs.

Last year, for instance, we made a significant unconventional discovery in the San Joaquin Basin. Continued appraisal and drilling and testing this year established reserves and resources of approximately 50 million BOE. The full development of this discovery is expected to require drilling 100 wells. In addition to the 50 million BOE we've established, we are testing and/or planning wells in late 2013 and 2014 that, if successful, will double this volume.

Further, this concept has repeatability, and we plan to extend this play through much of our California acreage. Our 2013 exploration program, which includes 15 wells, is on track to deliver results consistent with prior years, and we continue to build inventory to ensure we have a robust exploration program going forward into 2014 and beyond.

Finally, I would like to briefly touch on our gas development prospects in the state. In the Sacramento Basin of northern California, we have established a sizable natural gas position, with over 318,000 net acres and 66 million cubic feet a day of dry gas production. We estimate that we operate, through our Vintage business, over 80% of oil production in the region. Our current focus in the area is to optimize our current production, mostly with inexpensive workovers and a modest drilling program of 8 new wells in 2013 and 14 wells in 2014. We believe that the range of possible projects that are available in our acreage gives us the ability to ramp up our development efforts with attractive returns at prices around $5 per Mcf.

Currently, we have identified total reserves and continued resources of about 300 Bcf. We believe that our acreage held about 10 Tcf of original gas in place, with about 2 Tcf currently remaining. As you can see, we have a large inventory of waterflood, steam flood and EOR opportunities in California in and outside of Elk Hills, as well as significant upside in unconventional opportunities. All of these opportunities will continue to be an important part of our California development plans for the future and will make California a significant growth asset for Oxy. The mix of projects in the next couple of years will be similar to this year, as we continue to commit a larger portion of our capital to lower decline projects to manage our capital program more effectively and control escalation and spending while achieving healthy production growth.

In closing, I would like to summarize the progress we have made against the goals we established at the beginning of the year. We are executing a $1.5 billion capital program this year, which takes into account the constraints of working in California. We expect to generate free cash flow after capital in excess of $1 billion. Our program incorporates opportunities resulting from improvements we are already seeing regarding permitting in the state.

We shifted our development program towards a higher percentage of low decline projects such as our water and steam floods. With continued improvements in permitting, we should be able to grow our capital spend to around $2 billion in 2014, with further increases beyond that, reaching around $2.5 billion annually on a sustainable basis. With this program, we expect to grow at least within the corporate target rates of 5% to 8% annually over the next 10 years, while earning returns of better than 20%.

We've improved our capital efficiency by about 15% year-to-date compared to the full year 2012. We expect to further improve on these results going forward, which will improve our finding and development costs and returns. We have reduced our overall operating expenses by 350 BOE, from $23.20 in 2012 to an expected average $19.70 for all of 2013. This reduction translates to cost savings of over $175 million for the year, contributing to our earnings and cash flow. We have identified at least 5,500 well locations, and we'll add more as we continue to evaluate additional acreage and project opportunities.

We're working on several new waterflood projects in addition to a number of floods, where we're engaged in redevelopment, expansion or optimization activities. We're taking advantage of the gas versus oil price differences and expanding our steam flood opportunities, giving us a highly profitable set of projects to work with going forward. We're continuing our focus on a number of unconventional opportunities across the state, including the Monterey shale, to give us further growth prospects.

And finally, we're continuing our focused exploration in 3D seismic acquisition program, which has delivered a high percentage of commercially successful projects, the most recent example being our significant unconventional discovery in the San Joaquin basin. We have a large and diverse portfolio of opportunities available to us across the state. We're very excited about the future of our California operations and the role that it will play in contributing to the company's overall growth.

I will now turn the call back to Steve Chazen.

Stephen I. Chazen

Thank you, Vicki. I'll now turn to our third quarter outlook. Domestically, we continue to expect solid growth in our oil production for the year. Based on nature and timing of our drilling programs this year, such as the steam floods in California and timing of several gas plant maintenance turnarounds in the Permian, we expect the production growth to occur in the second half of the year.

We have achieved the drilling targets we set in the first half of the year. As a result, we expect our second half average domestic oil production will be about 6,000 to 8,000 barrels a day higher than the first half average, the increase coming mainly from the Permian and California. We expect modest declines in our domestic gas and NGL production that we have seen in the second quarter to continue as a result of our reduced drilling on gas properties and natural decline, as well as additional gas plant turnarounds scheduled in our Permian business the rest of the year.

Internationally, we expect more cost pool depletions in our contracts in Qatar and Yemen, which will result in less cost recovery barrels from those locations. However, we expect total international production to be about flat in the second half of the year compared to the second quarter volumes, assuming no renewed pickup in insurgent activity in Colombia and stable spending in Iraq. We expect international sales volumes to increase in the second half of the year and recoup well over half the underlift we've expected in the first half.

In the first 6 months, capital spending was $4.2 billion, with $2.2 billion spent in the second quarter. We expect second half of the year spending rate to be higher. Our annual spending level is expected to be generally in line with the $9.6 billion program we have previously discussed.

The positive effect of our capital efficiency efforts has started to become noticeable in our spending patterns. As a result, we believe there is a reasonable possibility our total spending may be somewhat lower than the program amount I just mentioned, while still drilling the number of wells we set out as a goal at the beginning of the year.

As you can see, the business is doing well, and we're continuing to make progress on our operational goals. With regard to our strategic business review, we have presented various options to our Board of Directors. Our review of these operations is progressing well, although it is not yet complete, so the board will continue to evaluate the alternatives.

We expect to have additional information regarding our plans towards the end of the year. Finally, an affiliate of Plains All American filed a registration statement yesterday with the SEC for a public offering of interest in Plains' general partner. We own 35% of the general partner's interest, and we expect to monetize a portion as a part of our proposed offering.

Now we're ready to take your questions.
