PentaNova spuds Colombia wildcat

PentaNova Energy Corp. is targeting Colombia’s Early Miocene Jimol formation in the Maria Conchita Block at an estimated TVD of 8,000 ft.

PentaNova Energy Corp. is targeting Colombia’s Early Miocene Jimol formation in the Maria Conchita Block at an estimated TVD of 8,000 ft. The Istanbul-1 well was spudded on Feb. 27, and the company expects the well to reach total depth within 20-25 days. PetroNova will run continuous logging during drilling.

The block contains previous discoveries. The Aruchara-1 drilled by Texaco in 1980 and the Tinka-1 drilled by Ecopetrol in 1988 were tested at rates of 18 MMcfd and 3 MMcfd, respectively. Both wells produced from Jimol.

The wildcat is 50 km southeast from Colombia’s Chuchapa field, one of the country’s largest with 6 tcf of natural gas. The field produces about 30% of the country’s daily output. In the event of a discovery, the Istanbul-1 is 22 km west of the Promigas trunk line, a major pipeline connecting the coastal cities of Barranquilla, Santa Marta, and Cartagena.
