Suroco Energy Inc. Announces Cohembi-3 Well on Production at 1852 Barrels Per Day

CALGARY, ALBERTA--(Marketwire - May 24, 2011) -


Suroco Energy Inc. (TSX VENTURE:SRN) ("Suroco" or the "Corporation") is pleased to announce that the second appraisal well of the Cohembi oilfield in the Suroriente Block in Colombia has been placed on production at approximately 1852 barrels per day. The Corporation holds a 15.8% working interest in the Suroriente Block.

Mr. Alastair Hill, the Corporation's President and Chief Executive Officer commented, "Cohembi-3 is the third successful well in our multi-well appraisal and development drilling program in the Pinuna and Cohembi fields and with the Cohembi-3 well now tied-in, the total Cohembi field production from the three producing wells is stabilizing at approximately 4580 barrels per day (approximately 667 barrels per day net to the Corporation after royalty). The initial appraisal drilling of Cohembi has been very successful with each successive well encountering thicker, better quality reservoir which has proven to be oil-bearing throughout with no evidence of an oil-water contact. The drilling program will now shift over to the Pinuna oil field where we expect to commence drilling the Pinuna-4 well in early June."

Cohembi-3 Well Results

The Cohembi-3 well commenced production on May 14, 2011 with a variable speed electric submersible pump, and from May 17 to May 22, 2011 produced at an average rate of approximately 1852 barrels of 18 API gravity oil per day (approximately 270 barrels of oil per day net to the Corporation after royalties) with no significant water production. The producing pressure and oil quality confirm that Cohembi-3, which offsets the Cohembi-1 well by approximately 1.0 kilometre, is producing from the same large Villeta N oil pool as the Cohembi-1 and Cohembi-2 wells. Oil production from the Cohembi N oil field averaged approximately 4580 barrels per day (approximately 667 barrels of oil per day net to the Corporation after royalty) from May 17 to May 22, 2011, with no significant water observed in any of the three wells.

Cohembi Oil Field Development Planning

Delineation drilling of the Cohembi oilfield will continue in the second half of 2011, with the objective of determining the areal extent and geometry of the accumulation to allow finalization of the field development plan. The Corporation and its partner are together evaluating the feasibility of how the ultimate recovery might be improved by water injection. Part of that work involves analysis of the N sand core which was acquired in the Cohembi-2 well. The analysis results of this core indicates that the reservoir is very high quality, with average permeability of 3,500 millidarcies and average porosity of 25% for the 13 plug samples that were evaluated. Special core analysis designed to evaluate reservoir performance under water injection will commence in the near future.

The Corporation is a Calgary-based junior oil and gas company, which explores for, develops, produces and sells crude oil, natural gas liquids and natural gas in Colombia and Western Canada. The Corporation's common shares trade on the TSX Venture Exchange under the symbol SRN.
