The Company has 100% working interest in the block and is the operator.
Ronald Pantin, Chief Executive Officer of the Company commented: “this is an important exploration discovery for Pacific Rubiales and demonstrates the potential of both the Guama block and Lower Magdalena basin where the Company has a large exploration acreage position and is looking to increase its gas reserves to support its initiative to develop an LNG export market in the future.”
The Cotorra-1X well was drilled as an exploratory well after an earlier exploration success on the block, the Pedernalito-1X well drilled in 2010. The well targeted Porquero Medio sands and silts of Miocene age, a low-permeability play successfully tested by Pedernalito-1X. Cotorra-1X was drilled to a total depth of 7210 feet in mid-January. The petrophysical evaluation showed a total of 40 feet of net pay, with average 20% porosity.
The well was perforated only in the deeper pay zone, across two intervals; leaving overlying pay zones untested for further evaluation.
After clean-up while flowing through a 1/2″ choke, Cotorra-1X reached a maximum gas flow rate of 7.5 MMcf/d and 370 bbl/d 56 degrees API condensate, followed by a three-stage isochronal and one extended flow test through 12/64″ choke which flowed at 2.6 MMcf/d and 121 bbl/d condensate at 3137 psi well head pressure.
During the month, the Company also completed drilling the Apamate-2X exploration well on its 100 percent owned and operated La Creciente Block. The well failed to test hydrocarbon flow at economic rates and was plugged and abandoned.

Hyperdynamics Corporation today announced the Sabu-1 exploration well offshore Republic of Guinea was drilled to a total subsea depth of 2,224 meters, putting the well near the top of Cretaceous age sediments, and that the next string of 13-3/8 inch casing was successfully set.
Following retesting of the blowout preventer, the well was drilled to a depth of 2,304 meters. Drilling equipment problems were encountered, and drilling has been suspended while repairs are made. The delay is estimated to be approximately one week.
The Houston based company expects to test prospective upper Cretaceous sandstone reservoirs while it drills the Sabu-1 well to a total subsea depth of about 3,600 meters.
Ocean Endeavor completes seismic survey
Hyperdynamics also announced that the CGGVeritas Ocean Endeavor has completed acquisition of the 4,000-square-kilometer 3D seismic program in the deeper water portion of its concession offshore Guinea. Processing of the 3D data set is in progress, with the first preliminary time section results expected in March 2012.
Hyperdynamics operates the Guinea concession with a 77 percent participating interest, with the remaining 23 percent held by Aberdeen-based Dana Petroleum, a wholly owned subsidiary of the Korean National Oil Company. The well is operated through AGR, a well management company.

September 5th, 2011, Det norske oljeselskap ASA presented a plan for development and operation (PDO) of Jette to the Minister of Petroleum and Energy, Ola Borten Moe. The PDO was submitted on behalf of the partners in the Jette Group, which in addition to Det norske as operator, includes Petoro, Dana Petroleum and Bridge Energy.
Aldous Senior Vice President Projects, Bård Atle Hovd, says this is an important step towards developing Jette.
– We have now signed the third and final contract for the development phase. As soon as we receive the Ministry´s approval, we will embark on our first field development. We wish for a fast track development, enabling us to produce oil from Q1 2013
Jette is located in blocks 25/7 and 25/8, in the mid part of the North Sea. The field, which lies at a depth of 127 meters, will be produced with two horizontal wells, tied back to the Jotun floating production, storage and offloading vessel (FPSO).
Det norske has signed supplier agreements with three contractors. Cameron has been selected to supply the subsea production system. They will, amongst other, fabricate the X-mas trees and protective structures.
Subsea 7 will be responsible for engineering, procurement, fabrication and installation of a 6 kilometer flexible flowline and jumpers, installation of a 6 kilometer integrated services umbilical, X-mas trees and protective structures. They will also supply diver assisted tie-ins.
Aker Solutions is given the assignment to fabricate the 6 kilometer integrated services umbilical.
