GeoPark logs Jacana discovery on Llanos 34 Block in Colombia

The Jacana 3 appraisal well drilled by GeoPark Ltd. on Colombia’s Llanos 34 Block flowed 1,650 b/d of 15° gravity oil with 1% water cut through a 43/64-in. choke at 50 psi wellhead pressure during a 7-day test. The well was drilled to 11,008 ft TD and produces from the Cretaceous Guadalupe formation. GeoPark said further production history will determine the stabilized flow rate of the well.

The Jacana 3 was spudded in mid-June (OGJ Online, June 15, 2016). Jacana oil field was opened with Jacana 1, which flowed 1,880 b/d of 14.9° gravity oil with a water cut of 1.9% in September 2015 (OGJ Online, Sept. 2, 2015). The field is currently producing 5,700 b/d of oil from two wells, the company said. Jacana field lies southwest of large Tigana oil field on Llanos 34 block onshore Colombia. The block was erroneously reported as offshore in a previous story.

GeoPark has plans to drill six wells on the block this year, two of which will be exploration wells. The operator holds 45% operating interest in the 82,000-acre Llanos 34 block.
