Kangaroo-2 well flows oil at 3,700 bbl/d from Paleocene intervals, adding to earlier success, in offshore Santos Basin, Brazil

TORONTO, Jan. 6, 2015 /PRNewswire/ - Pacific Rubiales Energy Corp. (TSX: PRE) (BVC: PREC) (BOVESPA: PREB) today provided an update on oil flow test results in the Kangaroo-2 appraisal well, located in the shallow offshore, Santos Basin, Brazil.

The Kangaroo-2 appraisal well is located in exploration Block S-M-1165 and confirmed an 820 foot gross (442 foot net) oil column in Paleocene and Maastrichtian aged reservoirs, announced November 26, 2014. The Company has a 35% participating interest in the wells and five surrounding blocks. Karoon Gas Australia Ltd. (ASX:KAR) ("Karoon")  holds the remaining 65% interest and is operator of the block.   

As announced in a news release yesterday by Karoon (see Karoon's website: www.karoongas.com.au "Kangaroo-2 Appraisal Well Progress Report No. 7"), a production test (DST-2A) was conducted over a 12 hour period through three perforated intervals (combined 230 feet), in the Paleocene A, B and C sandstone reservoirs. A maximum flow rate of 3,700 bbl/d (stabilised rate of 3,450 bbl/d) of 33° API oil was attained through an 88/64" choke with a flowing tubing head pressure of 270 psi, a gas-oil-ratio ("GOR") of 540 cf/bbl, and no water or sand production.

A separate production test (DST-2) was conducted across the 59 foot lower perforated interval in the Paleocene C reservoir. In DST-2, a maximum flow rate of 2,500 bbl/d was attained through a 44/64" choke with a flowing tubing head pressure of 425 psi and a GOR of 450 cf/bbl. The well was then flowed on a 40/64" choke at a stabilised rate of 1,820 bbl/d with a flowing tubing head pressure of 420 psi, and a GOR of 450 cf/bbl. The oil produced in DST 2 was 31° API, with no water or sand. At the end of a main 24 hour flow period, the well was shut-in for a 48 hour pressure build-up period.

Ronald Pantin, Chief Executive Officer of the Company, commented:

"We continue to be very pleased with the results of the Kangaroo-2 appraisal well, which confirms a significant light oil discovery on our blocks in the offshore Santos Basin, in Brazil. Based on the flow rates achieved, analysis by the operator suggests that reservoir characteristics in the structure are excellent and would support flow rates of 6,000 to 8,000 bbl/d in a vertical producing well, and higher rates in a horizontal well bore. We look forward to continuing the exploration and appraisal drilling campaign throughout the first half 2015."

Production testing in the current Kangaroo-2 well bore is now completed and preparations are underway to commence a side-track program to better define resource size and recovery factors, whereby two separate side-tracks will be drilled from Kangaroo-2. Side-track-1 will be drilled to a down-dip location to target potential reservoirs on the eastern side of an interpreted fault. Side-track-2 will be drilled in an up-dip location to test reservoir and hydrocarbon potential towards the salt wall seal. The information from the ongoing operations in Kangaroo-2 will be used in assessing the commerciality of the Kangaroo oil field and for front-end engineering and design work.

Following the completion of all operations in the Kangaroo-2 appraisal well, the rig will be moved to drill the Kangaroo-West-1 exploration well, evaluating a separate prospect approximately 4.5 kilometers on the western side of the Kangaroo salt structure.

Factors that could cause actual results or events to differ materially from current expectations include, among other things: uncertainty of estimates of capital and operating costs, production estimates and estimated economic return; the possibility that actual circumstances will differ from the estimates and assumptions; failure to establish estimated resources or reserves; fluctuations in petroleum prices and currency exchange rates; inflation; changes in equity markets; political developments in Colombia, Guatemala, Peru, Brazil, Papua New Guinea and Guyana; changes to regulations affecting the Company's activities; uncertainties relating to the availability and costs of financing needed in the future; the uncertainties involved in interpreting drilling results and other geological data; and the other risks disclosed under the heading "Risk Factors" and elsewhere in the Company's annual information form dated March 13, 2014 filed on SEDAR at www.sedar.com.

Although the Company believes that the assumptions inherent in the forward-looking statements are reasonable, forward-looking statements are not guarantees of future performance and accordingly undue reliance should not be put on such statements due to the inherent uncertainty therein.

Production test results are not necessarily indicative of long-term performance or of ultimate recovery.

Boe Conversion

Boe may be misleading, particularly if used in isolation. A boe conversion ratio of 5.7 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. The estimated values disclosed in this news release do not represent fair market value. The estimates of reserves and future net revenue for individual properties may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation.
