Abstract
Abstract: Targeted Infill Drilling at Stratton Field Using 3-D
Seismic![Next Hit](/data/images/arrow_right.gif)
John R. Suydam, Dale T. Reitz
ABSTRACT
Stratton field is located on the Vicksburg flexure trend in Nueces and Kleberg Counties, South Texas. It has produced more than 2.8 Tcf of gas since 1937 from Frio fluvial/deltaic sandstones and Vicksburg shallow-marine sandstones. The field is a combination stratigraphic and faulted structural trap, and contains numerous highly compartmentalized sandstone reservoirs. Continuous infield drilling is required to keep the field producing, and 3-D seismic
data
have been used to select the best locations for these wells.
In 1992, an 8-mi2 seismic
survey was completed in the southern end of the field, and the resulting structural
interpretation
presented many more fault traps than were apparent in the 2-D
seismic
interpretation
. So far, all of the new wells drilled within the survey have encountered untapped compartments enclosed by fault traps. Furthermore, fault cuts in the new wells have always been within 20 ft of the position predicted by
seismic
data
.
