Petro Vista Energy has begun drilling of Morichito-5B deeper pool exploration and appraisal well at the Llanos Basin in Colombia. The company started drilling the well on March 18, 2011.
Petro Vista will drill the Morichito-5B with an identical drilling pad used in the 2010 field discovery well Morichito-5. It will drill to the bottom hole location about 1,400 feet southeast of the previous discovery. The depth of the planned well is 6,600 feet in Cretaceous Ubaue formation and it will complete the Phase 5 contract between the company and Colombia National Hydrocarbon Agency (ANH).
The main aim of the Morichito-5B well is to analyze the Mirador, Gacheta and Ubaque reservoirs potential, being a dual-purpose well. Moreover, the company is expecting the well to find similar reservoir gap that showed oil in the Morichito-5 well. This well must offer additional oil reserves and structural benefit for deeper Mirador sands. After buying logs and sidewall cores, The company should take around 14 days to drill Morichito-5B well after which logs and sidewall cores will be purchased and the decision for completion will be taken .
Also, Petro Vista will bring a work-over rig to test the Carbonera 5900-foot sand in Morichito-5 well that examined oil at rates of up to 375 barrels of oil per day in short-term drill stem tests in April 2010. It was unfeasible to verify the perfect flow rate of the well, because of rain and flood.
Petro Vista has planned to establish a unit for immediate production depending on the new Morichito-5B well results and the existing Morichito-5 well results.
