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.
