Secondary natural gas recovery: Targeted technology applications for in-field reserve growth. Annual report, August 1988-August 1989
Activities during the year comprised screening and selection of gas fields for detailed studies; integrated geological, petrophysical, geophysical, and engineering analyses of the fields selected; and data acquisition in cooperative wells. A comprehensive workplan was prepared, and a methodology for geological and engineering screening of sandstone reservoirs was developed and applied to leading candidate fields. Contacts made with field operators resulted in active participation of Mobil Exploration and Producing U.S., Inc., and Shell Western Exploration and Production Inc. Lake Creek, Seeligson, McAllen Ranch, and Stratton-Agua Dulce fields were selected for study. These fields are representative of a spectrum of depositional systems and reservoir heterogeneities in highly productive gas reservoirs in the Texas coastal plain. Producing intervals are fluvial Frio reservoirs in Seeligson and Stratton-Agua Dulce fields, deltaic Vicksburg reservoirs in McAllen Ranch field, and deltaic Wilcox reservoirs in Lake Creek field. New data, comprising cores, open- and cased-hole logs, vertical seismic profiles, and sequential formation-pressure tests, were acquired in two wells in Seeligson field and in one well in McAllen Ranch field. Results to date suggest that reservoir heterogeneity can be defined using integrated geologic, geophysical, and engineering data.
