EOG Resources Inc., Houston, will drill several wells in 2010 to prove its belief that Jurassic Bossier dry gas pay exists on at least half of its 160,000 acres in the Jurassic Haynesville play in Northwest Louisiana and East Texas.
The Sustainable Forest horizontal well in DeSoto Parish, La., flow-tested at 13 MMcfd at 7,625 psi flowing tubing pressure, said Mark G. Papa, chairman and chief executive officer.
"It looks to us based on a couple of months' production from the Sustainable Forest well as if productivity and reserves from the Bossier are about identical to a typical Haynesville well," Papa said on a Feb. 10 conference call. EOG monitored the well to make certain the frac job stayed in Bossier and didn't penetrate the Haynesville about 200 ft deeper.
The two formations, which EOG will develop with separate wells, have similar maturation, and clay is slightly higher in the Bossier, the company said.
EOG is completing another Bossier well and plans to drill 70 gross Haynesville and Bossier wells in 2010, most of which will be Haynesville wells.
Papa said EOG subscribes to a theory that if an operator may increase the ultimate recovery of a Haynesville well if it doesn't pull the well quite so hard in the first year on production, but he said the company doesn't have enough data to confirm that the practice works.
