On 6 November 2017, GeoPark announced that its Tigana Norte-3 appraisal well in the Llanos Basin LLA-34 Block produced 970 bo/d of 15deg API oil with less than a 0.25% water cut in the Late Cretaceous Guadalupe Formation and is already on production. The production test was conducted with an electric submersible pump through a choke of 32/64" and a wellhead pressure of 129 psi. The well, which is assumed to have spudded in September 2017, reached a TD of 3460m and encountered net oil pay in the Guadalupe and Mirador Formations. The well was drilled to a bottom hole location 15m down dip of Tigana Norte-1, which was the lowest known oil and did not encounter the oil-water contact. The appraisal is located 690m to the west of the Tigana Norte-2 development well and potentially extends the Tigana/Jacana complex to the NE. Tigana Norte-3 was drilled outside of the 3P outline in a 2016 independent reserves certification report. Tigana Norte-4 is currently being drilled to further delineate the NE boundary of the field. A production test conducted on Tigana Norte-2 with an electric submersible pump in the Guadalupe Formation, resulted in a production rate of 1,980 bo/d of 14.7 degrees API, with less than 1% water cut and the well is currently producing 2,600 bo/d with les than a 0.5% water cut. The Tigana Norte-1 NFW discovery was drilled in 2014 and lies to the NE of the Tigana, Tigana Sur, Tigana Sur Oeste and Jacana discoveries made in the last four years. GeoPark operates the block with 45% WI and Parex Resources holds the remainder.
