Drilling Activity Summary

Description

Anadarko Petroleum Corp. completed two Weld County, Colo., wells in the Denver-Julesburg Basin. The Wattenberg Field discoveries were drilled from a single pad in Section 7-1n-67w. The #7-10HZ Ranger produced 29 bbl of 43° API oil, with 63,000 cu ft of gas and no reported water per day from commingled Codell (8,499-13,496 ft), Fort Hays (10,412-12,022 ft) and Niobrara (10,850-11,079 ft). Drilled to 13,541 ft, the true vertical depth is 7,867 ft. It was tested on a 14/64-inch choke with a flowing tubing pressure of 1,500 psi and a flowing casing pressure of 2,500 psi. The #7-9HZ Ranger was drilled to 13,344 ft (7,744 ft true vertical) and flowed 30 bbl of 43° API oil and 63,500 cu ft of gas per day from Niobrara at fractured perforations at 8,412-13,306 ft. Gauged on a 16/64-inch choke, the flowing tubing pressure was 1,538 psi, and the flowing casing pressure was 2,000 psi. Anadarko is a subsidiary of Houston-based Occidental Petroleum.
