Abstract

During the 1980s, significant reserves have been developed from Hunton and Sycamore reservoirs subcropping beneath the basal Desmoinesian unconformity, on the east flank of the Anadarko basin in T2, 3N, R2, 3W. Earlier oil production from the giant Golden Trend field has been largely from several overlapping Pennsylvanian stratigraphic traps, with only a minor contribution from pre-Pennsylvanian reservoirs within the study area. Approximately 200 Hunton/Sycamore producers have been drilled since 1982 in a program that continues to be active and competitive, despite the general industry downturn. The economic success of this play is the result of seven major factors: (1) establishment of a large productive area with a nearly 100% success rate, (2) knowledge that the Hunton is primarily a fractured reservoir and does not require matrix porosity in the Bois D'Arc and Chimneyhill formations, as assumed by earlier operators, (3) recognition that the Haragan and Henryhouse Formations of the Hunton Group are productive, despite unimpressive log characteristics, (4) discovery that not only the local clean limestones, but also the widespread shaly, dolomitic siltstones of the Sycamore are productive, added an important second reservoir, (5) application of large-volume, high-rate, water fracs without proppant that lowered costs without sacrificing productivity, (6)more »« less

Prediction of pressure depletion from wireline and mud logs, Golden Trend field, Garvin County, Oklahoma

Conference Sorenson, R; White, F; Struckel, J - AAPG (Am. Assoc. Pet. Geol.) Bull.; (United States)

The Golden Trend, a giant oil field encompassing several overlapping Pennsylvanian stratigraphic traps on the eastern flank of the Anadarko basin, has undergone a resurgence in the 1980s with deeper drilling for pre-Pennsylvanian targets. Approximately 200 new wells in and near the Antioch Southwest, Panther Creek, and Elmore Northeast waterflood units (T2, 3N, R2, 3W) have encountered evidence of undrained reserves in both established and new pay intervals of Pennsylvanian Hart and Gibson sandstones. Although all porous Hart and Gibson sandstones in the study area were originally oil bearing, evaluation of the state of depletion is necessary for planning futuremore »« less
Correlation and facies analysis in exploration for subtle traps within Hunton Group, Oklahoma

Conference Fritz, R - AAPG (Am. Assoc. Pet. Geol.) Bull.; (United States)

The bulk of Hunton production to date is associated with rather well-defined structural and/or truncation-style traps. Yet the trapping mechanism in these settings, to a large extent, depends on the development of particular depositional facies within the Hunton Group. Accurate correlation and subdivision of the Hunton require an understanding of the overall depositional environment and history. The depositional model for the Silurian Chimneyhill and Henryhouse formations and the Devonian Haragan and Bois d'Arc formations is a carbonate ramp. Both aggradational and progradational sequences formed, as did several unconformities during periods of erosion and nondeposition. The Frisco, however, was deposited onmore »« less
Geology and development of Mills Ranch complex: world's deepest field

Journal Article Jemison, Jr, R - Bull. Am. Assoc. Pet. Geol.; (United States)

The Mills Ranch complex, located on the southwest edge of the deep Anadarko basin in the southeast corner of Wheeler Co., Texas, is fast developing into one of the largest fields in the deep Anadarko. The complex, part of a deep buried granite uplift extending northwest-southeast along a large thrust fault, is complicated by numerous faults and unconformities. The discovery well of the deep Mills Ranch Hunton play, the Freeport Oil Co. 1 Sidney Fabian, was drilled in 1972 to a depth of 21,640 ft (6492 m) and completed at a calculated open flow rate of 93 million CF/day.

Development of Mills Ranch complex, Texas and Oklahoma

Conference Jemison, Jr, R - Am. Assoc. Pet. Geol., Bull.; (United States)

The Mills Ranch complex is fast developing into one of the largest fields in the deep Anadarko Basin. This complex is part of a deeply buried granite uplift which extends northwest to southeast for 15 m (24 km) or more from Wheeler County, Texas, into Beckham County, Oklahoma. It is a long narrow anticlinal feature paralleling a northwest- to southeast-striking thrust fault and is complicated by numerous faults and unconformities. The discovery well of deep Mills Ranch-Hunton play which started a large drilling program was the Freeport Oil Co. 1 Sidney Fabian which was drilled in 1972 to a depthmore »« less
Hunton geology of the Star-Lacey field, Blaine and Kingfisher Counties, Oklahoma

Journal Article Withrow, P - Shale Shaker; (United States)

The Star-Lacey Area is an example of the type, size, and quality of stratigraphic trap reservoirs that occur in this part of the Anadarko Basin. The top of the Hunton is an eroded surface with topographic relief that can effect structure maps drawn on this horizon. The thickness of zones within the Hunton Group varies throughout the area. These variations are not related to post-Hunton erosion. There is evidence that several unconformities exist within rocks of the Hunton Group. Porous dolomite occurs in the Hunton Group at all stratigraphic levels. The porous dolomite in the Chimneyhill Formation may be amore »« less
