    Bakken

    You probable saw XTO news release where they are buying in big time.

    XTO as they did in BS willing to lay out big bucks for prime property and then doing good job in exploiting

    • G, I imagine that the deep-pocket companies are tieing up as many NG shale leases as possible. Bakken is interesting and Palo-Duro Bend shale in N. Texas ( 7K ft to 10K ft deep and 500ft to 1000 ft thick) is said to have the about the same NG content as Barnett.

      • G. Just saw this on Platts:

        New shale gas discoveries
        After cracking the Barnett, producers have continually rolled out announcements of new shale gas finds over the past two years:


        Fayetteville Shale Arkansas, 180 Bcf recoverable Leader: Southwestern Energy
        Woodford Shale Oklahoma, 3-6 Tcf recoverable Leader: Newfield Exploration
        Marcellus Shale West Virginia, Pennsylvania, New York Leaders: Chesapeake Energy, Atlas Energy, Range Resources
        Haynesville Shaler Louisiana, 20 Tcf recoverable Leader: Chesapeake Energy
        Ootla Shale British Columbia, 9-16 Tcf recoverable Leader: Apache



        Mitchell spent 10 years perfecting methods for developing gas in the Barnett and, in the words of Devon's Hall, "Our experience with unconventional wells is that every one is different. From area to area they are idiosyncratic."

        But once a driller has cracked the code, as Devon feels it has done in the Barnett, "we kind of do the same thing over and over. We don't science every well."

        Devon, which like most drilling companies working in shale plays, is tight-lipped about its drilling techniques, varies its tactics in the Barnett.

        "We use different technologies in Johnson County," Hall said. "Different completion practices, more horizontal drilling. It's very thick shale. Horizontal drilling will be used for thick shale, while to the west and southwest it may be a vertical play."

        The characteristics of the 35,000 successful shale-based gas wells in the US tend to be the same: they are shallow and give up about half their gas production in the first year of life, with the other half produced over a typical 30-year life span.
