Abstract: Trimble Field, Smith Co., Ms: 100 BCF of By-Passed Pay at -7000'

By

Robert D. Schneeflock

The Upper Cretaceous Eutaw Formation of Mississippi has produced almost 2 TCFG since its initial discovery at Gwinville Field in 1944. Prior to Trimble Field, the last major Eutaw gas discovery in Mississippi was at Maxie-Pistol Ridge in 1951. Consequently, the Trimble discovery is the most important shallow gas find in the Interior Salt Basin in nearly 40 years. Trimble Field will likely develop into at least 20 wells with reserves in excess of 100 BCFG and a daily production rate of 40 MMCFG.

The Trimble discovery was made on a faulted structural closure that had been drilled twice before. Both operators drilled excellent locations but failed to detect low resistivity pay. In 1987, the discovery of gas on the third attempt by Cobra and Paramount was facilitated by the accidental discovery of Eutaw gas at Gitano field where a flow test of 2 MMCFGPD from an EPA-permitted salt water disposal well proved a new gas pay zone for the field. A petrophysical examination of the Gitano discovery and its implications to the "dry holes" at Trimble has initiated intensive industry activity in a renewed Eutaw play in Mississippi.
