Texas-West: Horizontal Clearfork shale results promising

Diamondback Energy Inc., Midland, Tex., said its Digger 601H well in Andrews County, Tex., tested at a 24-hr rate of 611 b/d of oil equivalent, 87% oil, from a 7,541-ft lateral in the Clearfork shale.

Diamondback Energy Inc., Midland, Tex., said its Digger 601H well in Andrews County, Tex., tested at a 24-hr rate of 611 b/d of oil equivalent, 87% oil, from a 7,541-ft lateral in the Clearfork shale.

Since being placed on production in early September, the Permian basin well’s oil rate has increased, reaching the maximum of 611 boe/d on Oct. 15.

Travis Stice, Diamondback chief executive officer, said, “This well has demonstrated a different production profile than our typical horizontal Wolfcamp B wells that tend to peak much earlier in the initial flowback period.”

The well was completed for $6.8 million, with 30 frac stages using a slickwater stimulation technique and is currently producing on an electric submersible pump.

“Further testing will be required to validate reserve estimates, but the results so far are encouraging,” Stice added.
