GeoPark announces continued drilling success in Colombia

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 drilling and testing of the Tigana 4 development well at a rate over 3200 bpd in the Tigana oilfield in the Llanos 34 Block (GeoPark operated with a 45% working interest) in Colombia.

GeoPark drilled and completed the Tigana 4 well to a total depth of 11 150 ft. A test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approximately 3200 bpd of 15.3 degrees API, with less than 1% water cut, through a choke of 44/64 mm and wellhead pressure of 100 lb per square inch. Additional production history will be required to determine stabilised flow rates of the well. Surface facilities are in place and the well is already in production.

The Tigana 4 well was drilled to total depth in 9.5 days with an estimated drilling and completion cost of US$3.3 million. At current oil prices and production rates, this well is expected to have a payback in less than six months and an IRR greater than 500%. The Tigana oilfield, discovered by GeoPark in December 2013, has a current production rate of approximately 15 000 bpd gross from eight wells that have produced over 10 million bbls of oil to-date. The field has attractive reservoir properties (porosity of 20-25% and permeability of 0.5 - 2.0 darcys) and high estimated recoveries in excess of 2 million bbls per well. For example, the Tigana Sur 1 and Tigana Norte 1 wells have already accumulated over 2.9 and 2.0 million bbls of oil each.

The Tigana field

The Tigana Field is along the same trend and fault line of the expanding Jacana Field. GeoPark is currently drilling the Jacana 6 appraisal well to test the southwest extension of the field – and its drilling campaign will continue with two - three additional wells in the Llanos 34 Block (GeoPark operated with a 45% working interest) before the end of the year.

James F. Park, Chief Executive Officer of GeoPark, said: “The Tigana/Jacana oilfield complex is shaping up to be a foundational asset and secure base for GeoPark’s short-to-medium term reserve and production growth. As of last year, this complex already had nearly 100 million barrels of 3P oil reserves gross (independently certified as of December 2015), with important reserve additions expected from recent 2016 drilling. This play is another example of why we believe Latin America is the most attractive region in the oil business today. It demonstrates the opportunity to move into proven low risk sparsely-developed hydrocarbon basins, introduce new geological play ideas to find new substantial oil reserves, profitably operate by increasing efficiency and innovation, and securely market production into a region thirsty for energy.”
