Drilling Activity Summary

Description

Denver-based PDC Energy announced results from three completions in Weld County, Colo. The DJ Field wells were drilled from a pad in Section 7-5n-66w. The #31C-11-L Bost Farm was drilled to 17,236 ft, and the true vertical depth is 7,145 ft. It produced 219 bbl of condensate, 543,000 cu ft of gas and 117 bbl of water per day from commingled perforations in Carlile at 7,463-8,102 ft; Codell at 8,102-17,049 ft; Fort Hays at 12,030-13,556 and Niobrara at 12,321-13,240 ft. Tested on a 16/64-inch choke, the flowing casing pressure was 2,178 psi. The #4C-11-L2 Bost Farm was drilled to a total depth of 17,195 ft, with a true vertical depth of 7,118 ft. It flowed 267 bbl of 52° API oil, 678,000 cu ft of gas and 113 bbl of water per day from commingled Codell (7,450-16,977 ft; Fort Hays (11,240-11,925 ft); Niobrara (11,520-11,749 ft); and Carlile (13,098-14,051 ft). Tested on a 16/64-inch choke, the flowing tubing pressure was 2,049 psi, and the flowing casing pressure was 2,354 psi. The #32N-11B-L Bost Farm was drilled to 17,668 ft, 6,908 ft true vertical. It was tested after 56-stage fracturing on a 16/64-inch choke flowing 691 bbl of oil, 1.078 MMcf of gas and 1,742 bbl of water per day from Niobrara at 7,495-17,480 ft. The flowing tubing pressure was 1,628 psi, and the flowing casing pressure was 1,896 psi.
