Devon Energy Corp. has announced it has brought online another successful spacing pilot and an oil well in the over-pressured oil window of the STACK play.
The Alma spacing pilot tested five wells per section across a single interval in the upper Meramec, delivering 30-day production rates averaging 1400 boe/d per well, of which 60% was light oil.
The Alma wells were drilled with 5000 ft laterals and were conservatively brought online with a 12/64-inch choke and gradually increased to a 20/64 in. choke.
The Company also recently brought online a record-setting oil well in the over-pressured oil window in southwest Kingfisher County. The Pony Express 27-1H was drilled with a 5000 ft lateral and achieved a 30-day average rate of 2100 boe/d, consisting of 1500 bpd, or 70% of the production mix.
“The Alma spacing pilot and record-setting Pony Express oil well are examples of the excellent results we are achieving in the Meramec formation, which has quickly evolved into the best emerging development play in North America,” said Tony Vaughn, Chief Operating Officer. “These successful well results help us further understand the optimal development scheme for Devon’s industry leading STACK position as we prepare for full-field development in 2017.”
Additional spacing tests underway
With the Alma test, Devon now has two successful spacing pilots in the core of the Meramec oil window. Production from the two-well Born Free pilot is achieving a 90-day average rate of 1500 boe/d per well (60% oil). The Born Free pilot wells were spaced 400 ft apart and landed in two intervals in the upper Meramec.
The next pilot Devon expects results from is the Pump House test in southwest Kingfisher County. The Pump House is testing seven wells per section in a single interval in the Upper Meramec and initial flow rates are expected in the third quarter of 2016.
To determine the optimal approach for developing stacked-pay intervals in the Meramec, the company is participating in several additional spacing pilots during the remainder of 2016.
