Santa Maria Petroleum Inc. completed testing of the Flami-1 well at the Llanos 27 block and is making plans to have the well put on extended production test.
The well is the second well drilled by NCT Energy Group C.A. Colombia, as operator of the Llanos 27 block. The well commenced drilling April 23 and reached a total depth of 2,835 m (9,300 ft) on May 31.
Well logs indicated an estimated 6 m (20 ft) of potential gross oil pay in the Mirador formation and 7 m (22 ft) in the Une formation. Testing operations of the Une formation and Mirador formation concluded.
On June 21, the company announced a new oil discovery in the Une formation of the Flami-1 well. Testing operations commenced on June 13, with the Une formation being perforated at the 2,769 m (9,086-ft) to 2,774 (9,100-ft) interval. Cumulative oil production over 60 hours was 3,786 barrels of oil (b/o).
Phase 2 of the test involved periodically stepping up the total fluid production rate to observe water cut and overall fluid production. Cumulative production over a 73-hour period was 5,496 b/o.
Testing operations commenced on July 1, with the Mirador formation being perforated at the 2,549 m (8,364-ft) to 2,552 m (8,372-ft) interval. Over a 48-hour test, the Mirador formation produced a total of 510 barrels of oil, and 1,448 barrels of water. The calculated average daily rate over the two days was 299 barrels of oil per day, and 899 barrels of water per day for a 75% water cut.
Given the lower productivity and higher water cut of the Mirador formation, it was decided to terminate testing and move toward placing the Une formation of the well on extended production test. The well will now be shut in while an application is made to the ministry of mines and energy in Colombia to put the well on an extended test. This application approval is expected to take four to six weeks, at which time the well can be put back on production and oil from the extended test sold to market.
