Latin American oil and gas company Geopark has conducted successful testing of the Jacana 6 appraisal well in the Jacana Oil Field of Llanos 34 Block, Colombia.
Geopark operates this field with a 45% working interest.
GeoPark drilled the well to a total depth of 11,684ft.
It conducted a test with an electric submersible pump in the Guadalupe formation in several sand units. The test witnessed a production rate of nearly 1,800 barrels per day (bpd) of 16 degrees API, with a 17% water cut, through a choke of 38mm / 64mm and wellhead pressure of 80 pounds per square inch.
Additional selective interval testing and production history are needed to determine the stabilised flow rate and water cut source.
The company claimed that the surface facilities are in place and the well is already in production.
The Jacana 6 well is located 1.7km southwest of Jacana 5 appraisal well. It was drilled to find out the western limits of the field. The Jacana 5 produces approximately 3,600 barrels of oil per day (bopd) with less than 1% water cut.
The success of this appraisal drilling has not only increased the field size but also improved production to more than 13,000bopd gross from six wells.
Independent reserve engineering firm DeGolyer & MacNaughton is currently analysing data to provide an updated reserve certification, which is expected to be released in February 2017.
Next year, GeoPark will concentrate on appraising and developing the Tigana / Jacana oil trend to assess the full extent of oil accumulation and increase its production.
GeoPark CEO James F Park said: “Great rocks, big traps, high-recovery wells, growing scale, supporting infrastructure, good geography, efficient low costs, and fast cycle self-funding cash flows, all being powered forward by GeoPark’s dependable and motivated operating team.
“The Tigana / Jacana oil complex is proving up all the ingredients of a world class oil play and a foundational asset to drive GeoPark’s value growth now and in the coming years.
"Our team continues to push out the boundaries of the field with every new appraisal well. We still have the opportunity to drill one to two more development wells before the end of the year, and are gearing up to drill another 15 plus wells to further appraise this play in 2017.”
