Devon Energy Corp. (NYSE: DVN) announced today it has successfully tested its third Meramec spacing pilot and commenced production on two high-rate, extended-reach lateral oil wells in the core of the over-pressured oil window of the STACK.
The Pump House spacing pilot tested a seven-well pattern across a single-section interval in the upper Meramec. Initial 15-day production rates averaged 2,200 oil-equivalent barrels (Boe) per day per well (55 percent oil) and cost $6 million per well. The Pump House wells were drilled with 4,700-foot laterals and utilized a completion design that deployed 2,200 pounds of proppant per lateral foot across 35 frac stages with perf clusters spaced 25 feet apart. To manage pressure and maximize value, these wells were brought online using an engineered choke management approach starting at a 14/64-inch choke and gradually increasing to a 26/64-inch choke over the initial 15-day period.
The Pump House wells are located in Kingfisher County adjacent to the Born Free pilot and three miles north of the Alma pilot. Production from the two-well Born Free pilot (announced first-quarter 2016) continues to perform exceptionally well, averaging a 120-day rate of 1,400 Boe per day per well. The five-well Alma pilot has achieved a 60-day average rate of 1,300 Boe per day on a per well basis.
