GeoPark Provides Update And Internal Reserve Estimate For The Tigana Oil Field In The Llanos 34 Block In Colombia

GeoPark Limited ("GeoPark") GPRK, the Latin American oil and gas explorer, operator and consolidator with operations in Chile, Colombia, Brazil, Argentina and Peru, provides an update and preliminary internal reserve estimate for the Tigana oil field in the Llanos 34 Block in Colombia. GeoPark operates and has a 45% working interest in the Llanos 34 Block. From well drilling and production information to date, 3D seismic mapping, and a field area size estimate of 3,000-4,000 acres, GeoPark's preliminary internal original oil in place (OOIP) estimate is 140-170 million barrels of oil (mmbo) and preliminary internal 3P gross reserve estimate is 45–65 mmbo for the Tigana oil field. Additional appraisal drilling will be required to delineate the Tigana field and, therefore, the above figures are preliminary and subject to change with new information. GeoPark discovered the Tigana oil field in December 2013 and, since that time, its team in Colombia has moved efficiently to: Drill a total of eight wells; Put seven wells in production with a total current rate of approximately 11,000 bopd gross – and a water cut of approximately 3.5%; Install facilities and infrastructure to handle approximately 20,000 barrels of fluid per day ("bfpd") (with plans underway to expand to 100,000 bfpd); and Produce approximately 2.1 million barrels of oil to date. The Tigana field represents a combination trap with a structural component (to the east, west and north) and a stratigraphic component (to the south). Oil has been tested and is being produced from both the Mirador (approximately 21-29° API crude oil) and Guadalupe (approximately 15.5° API crude oil) formations. DeGolyer & MacNaughton ("D&M"), the independent reserve appraiser, is currently evaluating information on the Tigana field and will perform an updated reserve certification as of December 2014. As a reference, at the end of 2013, with only two wells drilled, D&M certified 3P reserves of approximately 14.6 mmbo gross (6.6 mmbo net) for the Tigana field under PRMS. At the end of 2013, for GeoPark's oil and gas properties in Chile, Colombia and Brazil, D&M certified total net 3P reserves of 131 mmbo (and 2P net reserves of 70.2 mmbo) under PRMS. These figures do not include GeoPark's recent acquisition in Peru. The expanded Tigana field size represents increased value for GeoPark by providing an important opportunity to further grow production – with 30-45 potential new drilling locations – and to generate attractive financial returns over the next years. In addition to improving the overall risk profile of GeoPark's work program inventory, a larger field provides opportunities to reduce drilling, operating and transportation costs by improved efficiencies. Even in lower oil prices environments, the Tigana field will generate significant operating cash flows. As a reference, if WTI oil prices average $75-85 per barrel, operating netbacks for the field are estimated to be approximately $40-50 per barrel in 2015. James F. Park, CEO of GeoPark, said, "The reserve and value growth of the Tigana field is an important component of the overall success of our Llanos 34 Block – one of Colombia's leading production growth stories in recent years. After acquiring the Llanos 34 Block in 2012, GeoPark has grown production from zero to over 22,000 bopd gross (10,000 bopd net). This has resulted from a combination of our exploration success by developing and introducing a new geological play-type for the Llanos Basin and our operational success by being able to obtain permits, economically drill wells, construct facilities, develop transportation solutions and pro-actively work with local communities. And, all occurred within 2+ years following our success in identifying and closing on attractive assets in Colombia. Our results in the Tigana field this year have created an attractive low risk multi-year growing production asset and a solid complement to GeoPark's exciting inventory of ongoing projects in Chile, Colombia, Brazil, Argentina and Peru."
