Petroamerica Oil Corp. reported that following initial flow testing, its Las Maracas-4 well drilled on the Los Ocarros block in the Llanos Basin of Colombia, is now producing at a rate of approximately 1,500 b/d of oil with an electro-submersible pump from the Gacheta formation.
The well flow rate is currently restricted and it is anticipated that this oil rate will increase from 1,500 b/d to 2,000 b/d once access road and site congestion problems have been eased.
Upon testing, the well flowed naturally for a period of 88 hours from a 12-ft (3.6-m) perforated interval in the Gacheta formation. During this test, the well produced light oil at an average oil rate of approximately 1,400 b/d, with short-term peaks reaching more than 1,600 b/d.
Following this flow-test, the well was completed with an ESP and is now producing at restricted rates of approximately 1,500 b/d of oil with a 2.3% water-cut through a choke size of 23/64-in.
Petroamerica holds a 50% participating interest in the Los Ocarros block. The operator of the block, Cepcolsa, has transferred its 50% participating interest to Parex Resources Colombia Ltd. Sucursal, which is still pending approval by the Colombian National Hydrocarbon Agency.
