Drilling Activity Summary
Description
Bogota-based Cepsa has made an oil discovery at exploration well #1-Curiara on the El Porton Block in Colombia's Llanos Basin. The well flowed more than 800 bbl. per day of light 40-degree-gravity API oil from Mirador from a 5-ft. perforated interval. Tested on a 20/64-in. restricted choke over a 22-hour period, the well flowed 818 bbl. of oil and 3.4 million cu. ft. of gas. The wellhead flowing pressure was approximately 3,300 psi. Logs indicate 8 ft. of net pay and a possible gross hydrocarbon column of 50 ft. in Mirador. The well is currently shut in for a pressure build-up and further evaluation. The venture was terminated in Los Cuervos and did not evaluate the deeper reservoir objectives of Gacheta and Une. Cepsa is the operator, with 50% interest, in partnership with Petroamerica, holding 25%, and Talisman Colombia Oil & Gas with the remaining 25%.
