GeoPark follows Chachalaca success with Jacana discovery

GeoPark Ltd.’s Jacana 1 exploration well flowed 1,880 b/d of 14.9° gravity oil with a water cut of 1.9%, the company said. This discovery follows the company’s previously success with the Chachalaca 1 (OGJ Online, Aug. 28, 2015).

Jacana field lies southwest of large Tigana oil field on Llanos 34 Block offshore Colombia. Jacana 1 was drilled to a total depth of 10,900 ft. The zone of interest is at 10,200 ft, which includes the Guadalupe and Mirador formations. According to GeoPark, Jacana field follows the same fault trend as Tigana, and appears to be combination structural-stratigraphic trap.

The company expects to gather further production history to determine stabilized flow rates and the extent of Jacana field. As previously reported, GeoPark continues drilling operation on appraisal well Tilo 2. It plans drill a second Jacana appraisal well following completion of Jacana 1. GeoPark holds a 45% interest in Llanos 34 Block.
