Clayton Williams plans 10 Wolfcamp wells

Clayton Williams Energy Inc. expects to complete 10 horizontal wells this year in its 65,000-net-acre leasehold in the Delaware basin of Texas.

So far, it has drilled four wells into Permian Wolfcamp strata and completed two.

The company expects to finish the year’s drilling program in Reeves County with one well. The average time between spudding of sequential wells has fallen to 29 days.

Clayton Williams expects eight of the wells drilled this year to be completed in the Wolfcamp A section and two to be completed in Wolfcamp C.

It estimates completed well costs at $6.1 million for a 4,800-ft lateral and $7.5 million for a 7,200-ft lateral.

Two of the wells drilled so far this year are on production.

The company used its first slick-water frac in Reeves County for the more recent completion, the Collier 34-51 No. 1H, which has a 6,300-ft perforated lateral in the lower Wolfcamp A. The mid-July frac used 2,250 lb/lateral-ft of sand and 70 bbl/lateral ft of water.

Still in early stages of flow-back, the well had produced an average of slightly more than 2,100 boe/d during an initial 7 days.

The earlier completion, of a 4,600-ft lateral in Wolfcamp A, was in the Lowe 26 No. 1H during May. The company used a hybrid frac involving 1,800 lb/lateral-ft of sand and 43 bbl/lateral-ft of fluid.

Peak 30-day production from the well averaged 1,158 boe/d—74% oil and 13% NGL.

Of 25 Wolfcamp A wells the company drilled before this year, peak 30-day production averaged 732 boe/d.
