The Lazy Dalton Prospect lies on the Garza Platform, the ancestral carbonate platform to the Horseshoe Atoll. Play analysis reveals reasonable reserve size, production characteristics, acreage availability and discovery probability. The Strawn produces from numerous zones within the platform sequence on four-way structural closure. Seismic data has proven to be reasonably effective in delineating prospects. Two structural leads were identified from subsurface mapping, three 2D seismic lines were purchased and interpreted to confirm the leads. A five square mile 3D seismic survey was designed to encompass critical well control and define the prospect. The 3D survey revealed a drillable prospect on the primary prospective structure. The Eicke Ranch #1 was drilled and completed in December, 1994 for an IPF of 198 BOPD from the Strawn. Postdiscovery analysis and revised mapping resulted in the Eicke Ranch #2 being drilled and completed in December, 1995 for an IPF of 233 BOPD from the Mississippian.
We review play concept, geologic characteristics, data acquisition design, processing criteria, interpretation, and velocity pitfalls in the prospect area. Maps, logs and seismic data are shown which detail the prospect from inception through development.
