Frontera Resources Corp., Houston, is testing a well it says establishes natural gas potential in the undeveloped northwestern part of Mtsare Khevi oil and gas field in Georgia (OGJ Online, Feb. 4, 2010).
The company is testing Mtsare Khevi 32, which reached a planned depth of 370 m about 4 km away from Mtsare Khevi 31, drilled earlier.
Logs of the newer well indicated 33 m of net gas pay in three zones encountered in the field. Tests of a 14-m section of the lowest zone delivered 441 Mcfd of gas on a 9-mm choke and 761 Mcfd on a 16-mm choke. Frontera estimated absolute open flow of the tested zone at 847 Mcfd and planned to test uphole zones.
Meanwhile, the company placed the Mtsare Khevi 31 on production at about 10 b/d of oil from a 7-m reservoir section. The well cut 22 m of net pay, including 6 m of gas sands.
Frontera next will drill Mtsare Khevi 41, the third of 20 wells it plans to drill over the next 24 months to develop Upper Pliocene sands occurring at about 300 m.
The company operates and owns 100% interest in the field, which is in the western part of the Shallow Fields Production Unit of Block 12.
