High oil rate tested at Colombia's Candelilla-2

By OGJ editors
HOUSTON, Feb. 15 -- Petrominerales Ltd., a unit of Petrobank Energy & Resources Ltd., Calgary, reported a production rate of 15,800 b/d of 43° gravity light oil at less than 1% water cut at its Candelilla-2 well on the Guatiquia block in Colombia’s Llanos basin.

Petrominerales also set production casing at its Yenac-1 exploratory well on the Casimena block in the Llanos plains.

Candelilla-2 is producing from 10 ft of perforations in the Lower Sand 3 formation. Well logs indicated 88 ft of potential net oil pay in the Lower Sand 3 and 51 ft of potential net oil pay in three sands in the Guadalupe formation. The Guadalupe intervals will be tested later.

Candelilla-1, first well on the Candelilla structure, flowed naturally at an average sustained 12,400 b/d of 44° gravity light oil since being placed on production Dec. 31, 2009.

Production from the wells is restricted to a combined 27,000 b/d due to flowline limits. An additional 4½-in. flowline will be installed later this week to allow production to increase to current facility capacity of 30,000 b/d of fluid. The facilities are being expanded to handle 45,000 b/d of fluid for Candelilla-2 and Candelilla-3, to spud this week.

Candelilla production will be tied into the Corcel central processing facility in the second quarter of 2010. With the addition of Candelilla-2, company production totals 43,800 b/d.

Meanwhile, logs at Yenac-1 indicate 42 ft of potential oil pay in the Mirador formation. Total depth is 8,334 ft. After Yenac, the first exploration well in Petrominerales’ 13-well Llanos plains exploration program, the rig will move to the Mapache block to spud Mapana-1, the first of 10 exploration wells planned for the Mapache block in 2010.
