GeoPark, a leading independent Latin American oil and gas explorer, operator and consolidator with operations and growth platforms in Colombia, Chile, Brazil, Argentina, and Peru, has announced the successful drilling and testing of the Tigana Norte 4 appraisal well in the Tigana oil field in Llanos 34 block (GeoPark operated, 45% WI) in Colombia.  

GeoPark drilled and completed the Tigana Norte 4 well to a total depth of 11,730 feet. Oil shows during drilling and petrophysical analysis indicated the potential for hydrocarbons in both Guadalupe and Mirador formations. A production test conducted with an electric submersible pump in the Guadalupe formation resulted in a production rate of approx. 1,900 bopd of 14.1 degrees API, with approx. 1.8% water cut, through a choke of 34/64 inches and wellhead pressure of 178 pounds per square inch. Bottomhole pressure recorders from latest testings performed indicated a producing drawdown of approx. 30%. Additional production history is required to determine stabilized flow rates of the well. Surface facilities are in place and the well is already in production.   

The Tigana Norte 4 well follows the recently drilled Tigana Norte 3 and Tigana Norte 2 wells (currently producing 4,600 bopd with less than 0.2% water cut in aggregate) and extends and broadens the Tigana oil field towards the northeastern limits of the Llanos 34 block. The well was drilled outside the 3P reserve outline defined in the 2016 DeGolyer and MacNaughton (D&M) reserves certification, to a bottom-hole location that is approx. 75 feet down dip of the Tigana Norte 1 well (previous lowest-known-oil in the 2016 D&M reserves certification), and did not encounter the oil-water contact.   

GeoPark is currently drilling the Tigana Norte 5 well to a bottom-hole location that is further down dip of Tigana Norte 4 well to further delineate the northeastern boundaries of the Tigana oil field.
