La Cortez Energy, Inc. on Monday provided the following operational update on the work-over activity conducted on the Mirto-1 well.

Maranta Block – Mirto Field

As previously announced, the work-over on the Mirto-1 well was initiated on August 8th, 2011, with the objective to initiate a long-term production test on the Villeta N sand, which is the same zone that is producing in the Mirto-2 well. The work-over operation was completed on August 23rd, and the well was immediately put on production with the following initial results during the period from August 23rd to September 10th: Average gross production before royalties was 334 bopd of 15 degree API oil, with an average Base Sediment and Water (BS&W) of 1.5%. The well is producing by Electro Submersible Pump (ESP), and is stabilizing at 820 psi (flowing pressure at the ESP inlet) which is the expected pressure needed to maintain current production levels. Production on September 10th increased to 343 bopd (gross before royalties) with an average (BS&W) of 0.5%, indicating a continuous reduction in the water cut as expected for this particular reservoir. The well will be placed on long-term production testing with the purpose of monitoring production behavior as well as to gather additional technical data.

The Mirto-2 well continues producing with an average rate of 484 bopd for the year (gross before royalties), and with an average BS&W of 0.7%. The well continues producing from the Villeta N sand with flow pressure stable at 1065 psi, indicating the potential to increase the ESP frequency in order to maintain production levels closer to 500 bopd.

Current production from the Mirto-1 and Mirto-2 wells is 756 bopd gross before royalties, or 151 bopd net (before royalties) to the company, an increase of more than 50% over the year to date average.

Andres Gutierrez, President and CEO of La Cortez, commented on the announcement, "We are very pleased with the initial results obtained from the work-over on the Mirto-1 N sand. The additional production represents a significant increase in net production to the company, and will give us the opportunity to further assess the results of the work-over, and work closely with Emerald Energy Plc. (the operator of the block) to finalize plans for future exploration activity on the block as well as to determine the production potential from the Villeta formation - U sand in the Mirto field."
