Discoveries mount in E. Texas Cotton Valley pinnacle reef play
Another sizable discovery and more operators are popping up in the expanding East Texas Jurassic Cotton Valley pinnacle reef gas play. Sonat Exploration Co., Houston, reported a large discovery and sizable participation in the play in late April. Sonat and its partners join Marathon Oil Co., which has dominated the play the past few years. Sonat started sales April from the 1 Fountain, a new field discovery in northwestern Leon County between McSwane and Branton gas fields. The discovery flowed at a rate of 30.3 MMcfd of gas with 5,060 psi flowing well-head pressure. TD is 14,379 ft. Sonat estimated reserves at the well, possibly the only one to be drilled into the reef, at 70--80 bcf of gas. Sonat in late April formed a joint venture to explore the trend with UMC Petroleum Corp., Houston, and two smaller private companies, Aspect Resources and MB Exploration. A map of the combined acreage was not available from Sonat at press time, but the accompanying map indicates UMC`s position as presented to financial analysts earlier this year.
