Devon Energy announces record STACK well reaching 6,000 BOED

Devon Energy announced that it has brought online a record-setting Meramec well and commenced production on several high-rate wells in the core of the over pressured oil window of the STACK play during Q2 2017.

The record-setting Privott 17-H well was brought online in southwest Kingfisher County and achieved a facility-constrained peak 24-hour rate of 6,000 oil-equivalent bbl per day (BOED) (50% oil). When compared against publicly available data in the STACK, the Privott well achieved the highest initial production rate of any well by a wide margin and is expected to recover in excess of 2 million BOE over the life of the well.

The Privott 17-H well was drilled with a 10,000-ft lateral and landed in the upper Meramec interval near the company’s Showboat development, which will spud in Q3. A key contributor to this prolific well result was an improvement in stimulated rock volume around the wellbore through a new proprietary completion design.

Devon also brought online four additional high-rate Meramec wells in the core of the over pressured oil window during Q2 that benefitted from the company’s recently enhanced completion design. In aggregate, these four wells attained an average 30-day initial production rate of 2,000 BOED. These well results were even more impressive on a per-lateral-foot basis, with average well productivity of greater than 300 BOED per 1,000 ft of gross perforated interval.

“The outstanding well results we’re achieving from our enhanced completion design in the STACK is another example of Devon’s technology leadership in the upstream space. This operational excellence is delivering best-in-class well productivity in this world-class play,” Tony Vaughn, Chief Operating Officer, said. “Looking ahead, we expect to continue to build operational momentum in the STACK as we transition our activity to multi-zone development drilling that will drive additional efficiency gains and maximize the value of our resource.”

Full-field development update

The unique library of information Devon has accumulated through participation in the majority of industry wells has positioned the company for its first multi-zone development. Devon will spud the Showboat development project, which includes approximately 25 wells across four landing zones, in Q3.

“Devon will continue to test development concepts including well density, multi-layer well stacking, intra-layer well staggering and further completion design improvements,” Wade Hutchings, Senior Vice President Exploration and Production, said. “This continual flow of data from our extensive position in the STACK will inform and improve our deep inventory of future multi zone developments and the overall value of our coveted STACK resource.”

To date, the company has three operated spacing pilots online in the core of the over pressured oil window. These highly successful tests, which were 5,000-foot laterals, have delivered average 180-day cumulative production rates of approximately 220,000 BOE per well, with oil approaching 50% of the product mix.

Overall, Devon’s premier STACK position encompasses more than 600,000 net acres by formation and is concentrated in the economic core of the play. In aggregate, the company has exposure to 5,400 risked locations and possesses tremendous upside with greater than 10,000 unrisked locations. Given the STACK’s excellent positioning on the North American cost curve, this franchise asset provides the company with high-return, sustainable growth opportunities for the foreseeable future.
