Petrominerales Achieves Record 3Q Results

Petrominerales reports a record third quarter 2007 financial and operating results fueled by an 87% increase in year-over-year production to 4,522 bopd and a $56.62 per barrel operating netback, a reflection of high world oil prices, our high quality assets, and Colombia's superior fiscal regime. Production has now increased to 8,130 bopd excluding Corcel-2 production. Our Corcel-2 well was tested from the initially completed perforation intervals over a 24-hour period at rates increasing to 3,100 bopd on natural flow.

Operational Update:

Third quarter 2007 production averaged 4,522 bopd compared to 2,848 bopd in the second quarter of 2007. The increase is mainly due to the Corcel-1 discovery well that was placed on an extended six-month production test, initially at 4,000 bopd increasing to current rates of over 4,500 bopd. Production has averaged 8,130-bopd to-date in November 2007 excluding test results from the Corcel-2 well. Significant further production additions are expected as a result of the recently drilled Corcel-2 well and our ongoing drilling programs at Corcel and Orito.
