In early October 2017, Occidental de Colombia (OxyCol) tested approximately 548 bo/d in the Cosecha V-01 NFW, on the Cosecha Block (Llanos Basin). The short-term testing results were from the Lower Carbonera Formation between 2,652m-2,653m. The next testing will take place on the adjacent interval above. OxyCol in September 2017, was planning to test three intervals in the Cosecha V-01 NFW, on the Cosecha Block (Llanos Basin). Two of the intervals are in the Upper Cretaceous (likely to be K1 or K2) and two in the Early Tertiary (Lower Carbonera Formation -possibly C5). The well was spudded on 31 July 2017 with the H&P "152" land rig to a TD of 3,003m, on 13 August 2017, according to local sources. The NFW was targeting the Carbonera Formation. The well is located about 2km southwest of the Rex Field (which is producing in the K3 Cretaceous Formation, and approximately 7km north east of the Cosecha Field, (producing in the Carbonera Formation). The Occidental de Colombia JV (Occidental Oil and Gas 75% and Repsol 25%) operates the Cosecha Block with 70% WI. Ecopetrol holds the remaining 30% WI.<P />
