Ecopetrol discovered hydrocarbons in the Tisquirama Este-1 exploratory well in the municipality of San Martin, Cesar.
In initial tests, the well produced 624 barrels of oil per day with a water cut of less than 1% and API gravity of 23°.
The well reached a depth of approximately 9,100 ft (2,773 m). The initial tests were performed in the Lisama formation using encapsulated electric submersible pumps. The presence of hydrocarbons was confirmed at an approximate depth of 7,900 ft (2,407 m) with a net pay zone of 45 ft (13 m) in three sands and porosities varying between 15% and 22%.
To determine the potential and size of the finding the company will perform more extensive production tests over the next few months and drill two delimitation wells.
Ecopetrol is the operator and holds all rights of the Tisquirama production agreement, signed with the National Hydrocarbons Agency in October 2007.
