Exploration Update: Kangaroo-2 well tests 3,700 bbl/d light oil from first test intervals, in offshore Santos Basin, Brazil, and successful exploration wells drilled in Colombia and Peru
Dec 23, 2014

TORONTO, Dec. 23, 2014 /CNW/ - Pacific Rubiales Energy Corp. (TSX: PRE) (BVC: PREC) (BOVESPA: PREB) provided today an exploration update highlighted by initial test results in the Kangaroo-2 appraisal well, located in the shallow offshore, Santos Basin, Brazil.

The Kangaroo-2 appraisal well was drilled in Block S-M-1165, approximately 300 meters (943 feet) up-dip from the Kangaroo-1 discovery well, and confirms a 820 foot gross (442 foot net) oil column in Cretaceous and Paleocene aged reservoirs in the structure. 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.   

As announced in a news release yesterday by Karoon (see Karoon website: "Kangaroo-2 Appraisal Well Progress Report No. 6"), production testing was conducted over a 36 hour flow period across an initial 27 metre (89 foot) lower interval in the target reservoir. A maximum oil flow rate of 3,360 bbl/d (stabilised rate of 2,300 bbl/d) was achieved through a 44/64" choke with a flowing tubing pressure of 690 psi and a gas-oil-ratio ("GOR") of 620 cf/bbl. Following a 57 hour shut-in pressure build-up period, a second test was conducted with an additional 40 metres (131 feet) opened to flow. In this second test, a maximum flow of 3,700 bbl/d (stabilised rate of 3,300 bbl/d) 38° API oil was attained through a 1" choke with a flowing tubing pressure of 430 psi, a GOR of 650 cf/bbl, with no CO2, H2S, sand or water produced, over a 12 hour test period.

A third test of intervals higher in the reservoir is expected to commence within the next seven days. A decision on a potential side-track program will be made following the completion of testing in the well bore. Karoon is evaluating commercial options and early production strategies for the Kangaroo structure, as a result of these tests.

Following completion of all operations in the Kangaroo-2 well, the rig will move to drill the separate Kangaroo West prospect, located approximately 4.5 kilometres from Kangaroo-2, on the western side of the Kangaroo salt structure.

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

"We are very pleased with the flow results of the first test interval in the Kangaroo-2 appraisal well, which confirms the significant discovery status of the Kangaroo prospect on our blocks in the offshore Santos Basin, in Brazil. Testing is ongoing, but initial 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 are looking forward to the results of the additional production testing in Kangaroo-2, and the drilling of the separate Kangaroo West prospect in early 2015.

"The results from Kangaroo-2 complete a very successful year of exploration for the Company. Over 10,000 bbl/d of new net light oil production in Colombia and Peru have been delivered through the drill bit this year from successful exploration wells and we have additional barrels behind the pipe from recently drilled wells. These results demonstrate the quality and value of our exploration portfolio and contribute to our net production which is expected to exit the year at between 151 to 152 Mboe/d."

Exploration Update

Peru – Block 131 (30% working interest)

The Los Angeles-1X well commenced extended testing of the Cushabatay formation on September 18, 2014.  The well and operations on Block 131 are operated by Cepsa S.A., who holds the remaining 70% working interest. As of December 18, 2014 the well was producing 2,157 bbl/d of 45° API oil with a 0.01% water cut, GOR of 29 cf/bbl, flowing naturally on a 32/64" choke, with a well head pressure of 235 psi.  Over the last three months of the long-term production test, the well has produced over 185.5 Mbbl of oil at an average rate of 2,090 bbl/d.  Since discovery, the well has produced a total of 233 Mbbl of oil.

The Los Angeles Noi-3X exploration well spud on December 6, 2014. The well is currently drilling ahead at 5,858 feet with a planned TD of 8,855 feet in the Copacabana Formation. The primary target of this well is the Ene Formation with a secondary target in the Cushabatay Formation.

Colombia – Guatiquia Block (100% working interest)

The Ardilla-1 exploration well spud during the third quarter of 2014. The well reached a TD of 12,825 feet on October 19, 2014. Petrophysical interpretation indicated the presence of 71 feet of net pay including seven feet in the Mirador, 17 feet in the Guadalupe and 44 feet in the Lower Sandstone-1 Unit (with no water contact present). The well was cased and perforated in the upper 14 feet of the Lower Sandstone-1 Unit. Production with an electrical submersible pump commenced on November 7, 2014.  Since then, the well has produced a total of 86 Mbbl of 21° API oil at an average rate of 2,038 bbl/d and an average water cut of 5.7%.

The Avispa-2 appraisal well spud on December 14, 2014 and is expected to reach total depth in early 2015.

The Gulupa-1 exploration well spud during the fourth quarter of 2014.  The well reached a TD of 10,650 feet on November 29, 2014. The well was cased and perforated in the upper six feet of the Guadalupe Formation. Testing with coiled tubing and nitrogen commenced on December 15, 2014. The well produced a total of 246 bbl of 14° API oil prior to shut-in for a pressure build up on December 17, 2014.  Over the flow test period, the well produced at an average rate of 114 bbl/d with an average water cut of 37%, average choke size of 55/64" and average tubing head pressure of 114 psi. Pending the results of pressure transient analysis of the pressure build up data, the well may be perforated in the Mirador formation to test other potential pay zones.

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.
