Pacific Rubiales Energy Corp news release with annotations

TORONTO, Feb. 25 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE; BVC: PREC) announced today, together with its joint venture partner Petrodorado Ltd. (a wholly owned subsidiary of Cap-Link Ventures Ltd. (TSXV:CAV)), the successful completion of a new discovery well (ME-1) as a Mirador producer in the Moriche block, located in the Llanos basin of Colombia.

Mr. Ronald Pantin, Chief Executive Officer, commented: "We are very pleased with the success of the first well drilled as part of the 2010 exploratory program for the block. The fact that the first well drilled this year resulted in a commercial discovery confirms our optimism as to the hydrocarbon potential of the block. We look forward to the drilling of the second well in the same structure at the earliest possible opportunity to optimize hydrocarbon recovery."

Mauritia East Prospect (Moriche Block) ME-1:

The directional well was drilled to a total measured depth of 10,182 feet with the primary target of Mirador (9531 feet to 9770 feet measured depth, true vertical depth of 9130 feet). The well encountered a net oil column of 32 feet (true vertical depth) with 21.3% porosity and oil saturation of 71.3%, based on petrophysical analysis. The well was tested with two different pump systems; the jet pump yielded a peak oil rate of 650 barrels of oil per day (bopd) of 14 degree API oil, while the Electric Submersible Pump (ESP) yielded a peak oil rate of 693 bopd of 14 degree API oil. The well will be completed with an ESP and put into production within the next 40 days. A second well is scheduled to be drilled on the same structure during the second quarter of 2010.

As previously announced, Petrodorado acquired from the company a 49.5% working interest in the Moriche Block - Mauritia East Prospect, located in the Llanos Basin of Colombia. In exchange for this working interest, Petrodorado agreed to fund 100% of the total investment for the current exploratory phase for the block, equal to US$5.53 million. The company retains a 37.5% working interest in the Mauritia East Prospect.

Pacific Rubiales, a Canadian-based company and producer of natural gas and heavy crude oil, owns 100 percent of Meta Petroleum Corp., a Colombian oil operator which operates the Rubiales and Quifa Blocks in the Llanos Basin in association with Ecopetrol S.A., the Colombian national oil company. Pacific Rubiales also owns 100% of Pacific Stratus Energy which operates the rest of the production fields in Colombia. The company is focused on identifying opportunities primarily within the eastern Llanos Basin of Colombia as well as in other areas in Colombia and northern Peru. Pacific Rubiales has a current net production of over 55,000 barrels of oil equivalent per day (after royalties), with working interests in 32 blocks in Colombia and Peru.

Information in this press release expressed in barrels of oil equivalent (boe) is derived by converting natural gas to oil in the ratio of six thousand cubic feet (Mcf) of natural gas to one barrel (bbl) of oil. Boe may be misleading, particularly if used in isolation. A boe conversion ratio of 6 Mcf: 1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
