PETROLIFERA PETROLEUM ANNOUNCES COMPLETION AND RESULTS OF LONG TERM TEST OF
BRILLANTE SE 1X WELL ON ITS 100 PERCENT-OWNED SIERRA NEVADA LICENSE IN UPPER
MAGDALENA BASIN ONSHORE COLOMBIA

CALGARY, Sept. 20 /CNW/ - Petrolifera Petroleum Limited (PDP-TSX) announces that it has concluded the flowing phase of a long term test of its Brillante SE-1X well in its 100%-owned Sierra Nevada License, Colombia. The 21-day extended flow test of the upper portion of the Cienaga de Oro ("CDO") reservoir was completed at 0630 hrs on Saturday, September 18th. Total recovery during the test equaled the government permitted volumes of 66 MMSCF of natural gas, 284 barrels of 57.3 degree API gravity condensate, and 28 barrels of water. Government permitted production rates during the final 24-hours of the flow period were 3.1 MMSCF of natural gas, 19.0 barrels of condensate, and 1.1 barrels of water.

Final analysis of the bottom hole pressure data is pending acquisition and recovery of bottom hole gauges within the next 42 days. That analysis will provide the technical basis for all future conclusions and estimates of reserves and resources. Nevertheless, it is appropriate to point out at this time that no flowing wellhead pressure loss was experienced during the flow test. The flowing wellhead pressure increased from 1,016 psi to 1,055 psi, while the daily natural gas production increased slightly from 3.0 to 3.1 MMSCF per day.

No reduction in wellhead flowing pressure or natural gas rate indicates that no limits to the CDO reservoir were encountered during the 21-day flow period. Management is extremely pleased with the results to date and on this basis, plan to implement an early production scheme that will allow for the production and sale of modest amounts of natural gas until a full development is completed.

Petrolifera Petroleum Limited is a Calgary-based crude oil, natural gas and natural gas liquids exploration, development, and production company with interests in eleven concessions or licenses in Argentina, Colombia, and Peru.

Forward Looking Information:

This press release contains forward looking information including, but not limited to, the planned implementation of an early production scheme for the recovery of natural gas from the CDO reservoir in the Brillante SE-1X well and anticipated increases in reserves and resources as a result of the long term testing of the Brillante SE 1X well. Forward looking information is not based on historical facts but rather on Management's expectations regarding the company's future growth, results of operations, production, future capital and other expenditures (including the amount, nature and sources of funding thereof), competitive advantages, plans for and results of drilling activity, environmental matters, business prospects and opportunities and expectations with respect to general economic conditions. Such forward looking information reflects Management's current beliefs and assumptions and is based on information currently available to Management. Forward looking information involves significant known and unknown risks and uncertainties. A number of factors could cause actual results to differ materially from the results discussed in the forward looking information, including but not limited to, risks associated with the oil and gas industry (e.g. operational risks in development, exploration and production, unavailability of or delays in receipt of required equipment, permits or authorizations, delays or changes to plans with respect to exploration or development projects or capital expenditures; the uncertainty of reserve estimates; the uncertainty associated with geological interpretations; the uncertainty of estimates and projections in relation to production, costs and expenses and health, safety and environment risks), the risk of commodity price and foreign exchange rate fluctuations, the uncertainty associated with negotiating with foreign governments and third parties located in foreign jurisdictions and the risk associated with international activity. Certain approvals and/or permits are required in order to proceed with planned development and production of the Brillante SE 1X well and timing of receipt of these approvals and permits will impact the timing for implementation of the early production scheme and subsequent development plan for production of natural gas at Brillante. Additional risks and uncertainties associated with Petrolifera's future plans are described in Petrolifera's Annual Information Form for the year ended December 31, 2009. Although the forward looking information contained herein is based upon assumptions which Management believes to be reasonable, the company cannot assure investors that actual results will be consistent with this forward looking information. This forward looking information is made as of the date hereof and the company assumes no obligation to update or revise this information to reflect new events or circumstances, except as required by law. Because of the risks, uncertainties and assumptions inherent in forward looking information, prospective investors in the company's securities should not place undue reliance on this forward looking information.
