Title: Slant Hole Completion Test, Cozzette and Paludal production testing

Conference ·
OSTI ID:10128381

The Slant Hole Completion Test has been successful in providing good technology transfer to the oil and gas industry. The gas-producing rate from the Cozzette horizontal open-hole interval was significantly greater than from offset vertical wells. The source of water production from the Cozzette is not presently understood. Diagnosis of the water production mechanism is vital to economic exploitation of the Cozzette gas resource using horizontal well technology. Stimulation in a high-angle cased and cemented wellbore, such as the Paludal 2, 3 and 4 intervals in SHCT No. 1, is more difficult because of high near-wellbore stress that results in higher treating pressures. Low gas production potential following the Paludal 2, 3 and 4 stimulation may result from damage to the natural fracture system resulting from casing cementing operations. Comparison of gas production rates in SHCT No. 1 and MWX No. 1 following similar stimulations in the Paludal 3 and 4 intervals, indicate there is no advantage to a hydraulic fracture treatment in a slant wellbore when compared to a vertical wellbore.
