GeoPark’s Jacana 5 well further extends Colombian oil field

The GeoPark Ltd.-operated Jacana 5 appraisal well on Llanos 34 block in Colombia reached a TD of 11,467 ft, testing with an electric submersible pump in the Guadalupe formation at 2,500 b/d of 15.5° gravity oil.

Oil flowed through a 41/64-mm choke with wellhead pressure of 90 psi, showing less than 1% water cut. The firm says additional production history is required to determine stabilized flow rates of the well. Surface facilities are in place and the well is already on production.

The Jacana 5 well followed the recent Jacana 4 and Jacana 3 wells, which expanded the size of Jacana field by extending its northwestern limit (OGJ Online, July 8, 2016). Jacana 5 was drilled 780 m north of Jacana 3 further down dip to a bottom-hole location below the previous lowest-known oil.

With these results, the test of the Jacana 5 well further extends the limits of the field. GeoPark expects to continue exploring and appraising the Tigana-Jacana oil trend to determine the full extent of the oil accumulation.

Once the testing of the Jacana 5 well is completed, the drilling rig will move northeast along the trend to Tigana field, followed by other locations, to continue GeoPark’s program of five more wells on Llanos 34 block, of which the firm holds 45% working interest, before yearend.
