Title: Drilling, completion, stimulation, and testing of BDM/CNGD Well 3997, Lee District, Calhoun County, West Virginia

Abstract

This report discusses the detailed field operations in drilling, casing, completing, and stimulating the Hunter Bennett No. 3997 well located in Lee District, Calhoun County West Virginia. The project was designed and managed by BDM in cooperation with CNG Development Company. The well was spudded on November 9, 1990, and drilling was completed on December 14, 1990. The well was drilled on an average asmuth of 312 degrees with a total horizontal displacement of 2459 feet. The well was turned to a 90 degree inclination from the vertical over a measured course length of 1216 feet. Approximately 1381 feet of the well had an inclination higher than 86 degrees, while 2179 feet had an inclination greater than 62 degrees. The well was partitioned into five zones for stimulation purposes. Each zone is a little more than 300 feet long. The well was stimulated with nitrogen gas in zones one and two. Early production results are encouraging. The BDM/CNGD horizontal well averaged 147 mcfd of gas over the first week of production and, in week five, began to produce oil at a rate of about 2 bbl/day.

    This report discusses the detailed field operations in drilling, logging, casing, completing, stimulating and testing the Hardy HW No. l well located in Union District, Putnam County, West Virginia. The project was designed and managed by BDM in cooperation with Cabot Oil and Gas Corporation. The well was spudded on November 29, 1989 and was completed at a total measured depth of 6406 feet on December 29, 1989. The well was drilled on an average azimuth of 335 degrees with a total horizontal displacement of 2618 feet. Approximately 1035 feet of the well had an inclination higher than 86 degrees,more » while 2212 feet of the well had an inclination greater than 62 degrees. The well was partitioned into five zones for stimulation purposes. Four zones were stimulated during three stimulation operations (Zones 3 and 4 were stimulated together). Zone 1 stimulation was a successful foam frac while the stimulations on Zones 2, 3-4 were Partially successful. Initial gas production rates were 4.5 times greater than the natural production rate. After 21 months, gas produced from the BDM/Cabot well has declined at a rate about one-half that of a conventional vertical well in the area. This horizontal well is projected to produce 475 million cubic feet of gas over a 30-year period.« less

    Devonian-shale gas production, from wells in a research area surrounding the Sterling Drilling Production Company, Jarvis No. 1143, located in Calhoun County, West Virginia, is from intervals affected by thrust faults and/or associated shearing. Detailed whole-core description and Markov interpretation lead to the formulation of a depositional model of ongoing pelagic sedimentation of dark gray shales, periodically interrupted by turbidites consisting of thin siltstones and associated gray shales. A fracture model includes slickensides resulting from Alleghenian thrusting. The gas reservoir in the CSW No. 2 area suggests a combination of structure-induced fracturing, possibly of two distinct types, and relatively abundantmore » and thickly bedded siltstones.« less

    This report discusses the data collection and analysis procedures used to establish criteria for geologic and engineering studies conducted by BDM to select a general area for more detailed study and a specific site for the drilling of a cooperative well with an industry partner, the Consolidated Natural Gas Development Company (CNGD). The results of detailed geologic studies are presented for two areas in Calhoun County, West Virginia, and one area along the Logan-Boone County line in West Virginia. The effects of Appalachian Basin tectonics and the Rome Trough Rift system were identified on seismic lines made available by (CNGD).more » These helped to identify and define the trapping mechanisms which had been effective in each area. Engineering analyses of past production histories provided data to support selection of target areas and then to select a specific site that met the project requirements for production, reservoir pressure, and risk. A final site was selected in Lee District at the southwestern margin of the Sand Ridge gas field based on the combination of a geologic trapping mechanism and reservoir pressures which were projected as 580 psi with a stress ratio of 0.53.« less
