GeoPark Limited, a leading independent Latin American oil and gas explorer, operator and consolidator with operations and growth platforms in Colombia, Chile, Brazil, Argentina, and Peru1, has announced the successful testing of the Jacana 5 appraisal well in the Jacana oilfield in the Llanos 34 Block (GeoPark operated with a 45% working interest) in Colombia.
GeoPark drilled and completed the Jacana 5 appraisal well to a total depth of 11 467 ft. A test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approximately 2500 bpd of 15.5 degrees API, with less than 1% water cut, through a choke of 41/64 mm and wellhead pressure of 90 lb/ in.2 Additional production history is required to determine stabilised flow rates of the well. Surface facilities are in place and the well is already in production.
The Jacana 5 well followed the recent successful Jacana 4 and Jacana 3 wells which had expanded the size of the Jacana field by extending the north-western limit of the field. The Jacana 5 well was drilled 780 m north of the Jacana 3 appraisal well further down dip to a bottom-hole location below the previous lowest-known oil. It encountered oil in the Guadalupe formation and did not encounter the oil-water contact. With these results, the successful test of the Jacana 5 well further extends the limits of the field. GeoPark expects to continue exploring and appraising the Tigana/Jacana oil trend to determine the full extent of the oil accumulation.
Once the testing of the Jacana 5 well is completed, the drilling rig will move north-east along the trend to the Tigana field, followed by other locations, to continue GeoPark’s programme of five more wells in the Llanos 34 Block before the end of the year.
James F. Park, Chief Executive Officer of GeoPark, said:
“Congratulations to our team for the strong test results from the Jacana 5 well - and another important development in the expanding Llanos 34 Block success story. Although test rates are preliminary, it highlights the reserve potential of the Jacana field - where further appraisal and development drilling is required to delineate and understand the full extent of this productive field.”
