GeoPark Ltd.’s Tigana Norte 3 appraisal well has confirmed the Tigana/Jacana oil field’s extension toward the northeastern limits of Colombia’s Llanos 34 Block.

The company drilled and completed the well to a total depth of 3,460 m (11,352 ft). Oil shows during drilling and petrophysical analysis indicated the potential for hydrocarbons in the Guadalupe and Mirador formations. A production test conducted with an electric submersible pump in the Guadalupe Formation resulted in a production rate of about 970 barrels per day (bbl/d) of 15 degrees API, with less than 0.25% water cut, through a 32/64-in. choke and wellhead pressure of 129 pounds per square inch.

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, GeoPark said.

The Tigana Norte 3 well is located 690 m (2,264 ft) west of the recently drilled Tigana Norte 2 well, which is producing 2,600 bbl/d, and was drilled outside the 3P outline defined in the 2016 DeGolyer and MacNaughton reserves certification, to a bottom-hole location that is about 15 m (50 ft) down dip of the Tigana Norte 1 well (most recent lowest known oil), and did not encounter the oil-water contact. With these preliminary production test results, the Tigana Norte 3 well broadens the Tigana/Jacana oil field play towards the northeastern limits of the Llanos 34 Block.

GeoPark is currently drilling the Tigana Norte 4 well to further delineate the northeastern boundaries and to continue GeoPark’s work program to drill five more wells in the Tigana/Jacana oil field play before year-end.

GeoPark holds a 45% working interest in the Llanos 34 Block and serves as operator.
