La Cortez announced that Emerald, the operator of the Maranta Block where La Cortez will hold a 20% working interest, has begun drilling operations for the Mirto-2 exploratory well.
The Mirto-2 well will be drilled to an estimated target "measured depth" of 11,604 feet in order to test the Villeta formation N, U, and T sands, which are prolific hydrocarbon producers in the Putumayo basin.
The Maranta block covers an area of 90,459 acres (36,608 hectares) in the foreland of the Putumayo Basin in southwest Colombia. Emerald signed its E&P contract with the Agencia Nacional de Hidrocarburos ("ANH"), Colombia's hydrocarbon regulatory agency, pursuant to which it is exploring the Maranta Block on September 12th, 2006.
The Mirto-1 exploratory well, drilled last year, tested three sands as follows:
A workover job on the Mirto-1 well, which was completed on March 6, 2010, attempted to isolate a water production formation that La Cortez believed was coming into the well through poor cement bonding behind casing, as observed in the "Cement Bond Log". La Cortez concluded that the attempt to isolate the water production formation was not successful; therefore, both the operator and La Cortez have decided to continue producing from the well with a high water cut. The Mirto-1 well is currently producing an average of 120 bopd of 31.5 degrees API with a water cut of approximately 82%.
The Maranta block is adjacent to the recent 20 million barrel proven discovery of the Costayaco field made by Gran Tierra Energy, Inc. ("Gran Tierra").
Having fulfilled its payment obligations to Emerald for the drilling and completion of the Mirto-1 well, La Cortez has asked Emerald to file a request with the ANH for the assignment of the 20% working interest in the Maranta block to La Cortez and to assist La Cortez in obtaining its working interest from the ANH through reasonable means. Emerald will pursue this request as soon as it receives the ANH required support documentation from La Cortez, which is expected to be within the next two weeks.
Andres Gutierrez, President and CEO of La Cortez commented on the announcement, "We are very pleased to announce the initiation of drilling operations in the Mirto-2 well. We hope this well validates our analysis of a significant geological structure and the possibility to increase the company's production rate. We remain attentive to other opportunities in a variety of basins in Colombia that we believe have opportunities to allow La Cortez to build our production base and benefit from upside exploration."
