Maybe they are using the new completion procedure from Kodiak oil and gas. Shut down all wells next to new well being fracked. This stimulates the formations and improves old well performance. See Seeking Alpha dated Mar 5. Michael Fitzsimmons.
The Southern section of the North Stockyard creek don't have their permits.
The Frontier rig 24 hasn't arrived to well site yet.
The 4 batch wells to be drilled to the North are
1.) Drilled to TVD one after the other
2.) They start the horizontal on the 4th after TVD on that well
3.) They use a skiddable rig and move back to #3, then #2, then #1 horizontals
4.) Then they FRAC all 4 together (looks like August 2013).
