Devillier field, Chambers County, Texas: effects of growth faults and deltaic sedimentation on hydrocarbon accumulation in a stratigraphic trap
Devillier field is an overpressured gas reservoir producing from upper Vicksburg (lower Oligocene) Loxostoma B Delicata-age sands which pinch-out near the crest of an anticline located on the downthrown side of the Vicksburg flexure. The field is located 50 miles (80 km) east of Houston in NE Chambers County, Texas. The first year's production per well has averaged 1.0 billion cu ft of gas and 13,000 bbl condensate, for the 7 wells completed since the field discovery in 1975. Calculated open flows have ranged as high as 600,000 MCFD of gas from an average net-sand interval of 25 ft (7.6 m) at depths between 10,550 and 10,750 ft (3216 and 3277 m). The upper Vicksburg sediments are considered to have been deposited in a shallow-marine environment. The field pay, the Loxostoma sand, is interpreted to have been deposited in a delta distributary mouth bar.
