Location and background
In the Upper Magdalena Valley, the company, through the acquisition of Pacific Stratus, holds a 50% participating interest in the production from the Puli 7 well, which is operated by Interoil.
Geology
The Puli Block is located in the northern portion of the Upper Magdalena Valley Basin at the Girardot Sub Basin, within a geomorphologic depression that separates the Central from the Eastern Cordilleras of Colombia. This sub Basin is characterized by a high folding resulting in wide synclines and narrow anticlines formed by thrust faulting associated to the deformation front of the Eastern Cordillera.
The petroleum system for the area is composed of shales from the Guaduas Formation acting as a seal, sandstones from the Monserrate Formation and limestones from the Villeta Formation acting as the reservoirs, and organic rich shales from the Villeta Formation as the source rocks.
Production and Reserves
In 2007, average net production from Puli-7 was 115 bbl/d, 133 Mcf/d and 0.2 barrels of water per day, for an accumulated net total production of 76,008 barrels. Net proved producing reserves at Puli-7 amount to 44Mbbl.
