The Tempranillo North-1 well is located in the township of Aipe, Huila. Well drilling began in the final week of October and by December 2009 had reached a total depth of 10,235ft, equivalent to over three kilometers.
The well drilled through two layers of the caballos formation, where accumulations of hydrocarbons were found at three intervals. Upper layer sands revealed two intervals at depths below 8,500ft, with a net hydrocarbon thickness of 40ft. Lower layer sands are located below 9,700ft and revealed a net hydrocarbon interval of 16ft.
Short Drill Stream Tests (DSTs) performed during the month of January 2010 revealed that the caballos formation produced crude oil of 24 degrees API, with an average volume of 1,000 barrels per day supported by an artificial lift system, a low gas-oil ratio, and water cut of about 1%.
Tempranillo North-1 is the fourth discovery made in the Pijao-Potrerillo area during the last two years, after the discovery of Tenax, Arrayan and Tempranillo, Ecopetrol said.
