Ivanhoe Energy announces major technical breakthrough in its HTL (Heavy-to-Light) heavy-oil upgrading process

<< New configuration lowers capital and operating costs for HTL heavy-oil projects >>

Dr. Michael A. Silverman, Executive Vice President, Technology, of Ivanhoe Energy Inc. (TSX: IE; NASDAQ: IVAN), today announced a major technical breakthrough in the ongoing enhancement of the company's proprietary HTL (Heavy-to-Light) technology.

The breakthrough was achieved through a new process configuration developed by Ivanhoe Energy's in-house technical team at the company's newly commissioned Feedstock Test Facility in San Antonio, Texas. It confirms that the HTL technology now enables the production of "bottomless" synthetic crude oil through a simplified operation that delivers lower capital and operating costs. The benefits of this breakthrough will be realized in all of Ivanhoe's HTL heavy-oil projects, including the Tamarack Project in Canada, the Pungarayacu Project in Ecuador and additional target opportunities that have been identified in the Middle East, Asia, Africa, Latin America and Canada.

Corridor Successfully Fractures and Completes the McCully L-38 and P-47 Wells

Corridor Resources Inc. (TSX:CDH) reported the initial results of fracturing and flow-testing of the McCully L-38 and P-47 wells located in the northeastern segment of the McCully natural gas field in southern New Brunswick. The wells were fractured with liquid propane followed by flow-back and initial flow test operations. This was the first time that fracturing with propane was conducted in the McCully Field, as completion operations in previous years had mainly used combinations of water and methanol as the frac fluid. The positive results (described below) are attributed partially to reservoir characteristics and partially to the successful application of propane as the frac fluid. Corridor's technical staff is reviewing seismic and other data to identify a number of additional drilling locations in the vicinity of these wells for potential inclusion in the 2010 drilling program.

Petrominerales Ltd. ("Petrominerales" or the "Company") (PMG), a 67% owned subsidiary of Petrobank Energy and Resources Ltd. ("Petrobank") (TSX: PBG), announces that the Boa-1 exploration well is producing at over 6,000 bopd of 19 degree API oil at less than 1% water cut from the Lower Sand 1 formation.

The Lower Sand 2 tests encountered non-commercial quantities of hydrocarbons.

We are currently drilling the Corcel-A2 side-track, targeting the structurally highest point of the Corcel A structure to access by-passed Mirador and Guadalupe pay. We have reached the top of the Mirador formation and are preparing to run intermediate casing. We expect to have the well on production by the end of September.
