GeoPark Holdings Ltd. said it participated in three discoveries in the Llanos basin in Colombia.
The Max-1 well on the Llanos 34 block is testing 1,220 b/d of 15° gravity oil with 18% BS&W from the Guadalupe formation on an electric submersible pump. More tests are needed to determine expected and stabilized production rates. GeoPark operates the block with a 45% working interest.
Max-1 went to a TD of 11,505 ft. The Gacheta formation at 11,054-062 ft and 11,065-080 ft flowed at the rate of 149 b/d of 35.8° gravity oil on a 35-hr test. Guadalupe at 10,600-625 ft flowed 323 b/d of fluid with 6% BS&W for an average of 304 b/d of 14.8° gravity oil.
The Guadalupe at 10,456-490 ft averaged 299 b/d of fluid with 10% BS&W for an average 276 b/d of 14° gravity oil. The Mirador at 10,300-310 ft and 10,320-336 ft made 637 b/d of fluid, 75% BS&W, on a jet pump on a 26-hr test for an average 159 b/d of 22.8° gravity oil.
The Tua-1 discovery well on Llanos 34 is testing at 1,723 b/d of 18.2° gravity oil with less than 0.5% BS&W from Mirador on ESP. More tests are needed. The Guadalupe formation also tested heavy oil.
Delineation drilling at both discoveries is to start in the third quarter subject to regulatory and partner approval.
On Llanos Block 32 the P1 Energy-operated Maniceno-1 exploratory well went on production in July 2012 at 3,000 b/d of 28° gravity oil. The Samaria-1 exploratory well, drilled in June with potential oil pay in Mirador, Guadalupe, and Gacheta, is to be tested this month. GeoPark has a 10% working interest subject to regulatory approval.
On the Parex Resources Inc.-operated Llanos 17 block, in which GeoPark has 36.8% working interest subject to regulatory approval, the Mapora-1 exploratory well is to be plugged and abandoned and the Celeus-1 exploratory well finished drilling in April with potential oil pay in the C7 and Gacheta formations. Tests are planned for July 2012.
