Pacific Rubiales Announces a 45% Increase in Certified Total Prospective Resources and a 62% Increase in Certified Contingent Resources, in an Evaluation of its Exploration Blocks

TORONTO, Aug. 19, 2014 /PRNewswire/ - Pacific Rubiales Energy Corp. (TSX: PRE) (BVC: PREC) (BOVESPA: PREB) announced today the results of an independent resource evaluation for 36 of the Company's 60 exploration blocks in Colombia, Peru, Brazil, Guyana, Guatemala and Papua New Guinea ("PNG"). The 2014 resource evaluation was prepared by Petrotech Engineering Ltd. ("Petrotech") with an effective date of March 31, 2014 (the "2014 Resource Report").

The 2014 Resource Report selection of the 36 exploration blocks was based on a minimum criterion of 20 MMbbl of oil or equivalent of Pmean Resources, per block.

The 2014 Resource Report contains estimates of low case, best case, high case and Pmean case for both Contingent and Prospective Resources (see section "Resources" in the Legal Advisories for further information).

The following comparison is done on the best case estimates of the 36 exploration blocks evaluated in 2014 against the best case estimates of the 32 exploration blocks evaluated in 2012 (subject to no minimum criteria).

The 2014 Resource Report shows that the best case estimates of 36 exploration blocks totaling the sum of the gross Prospective Resources ("total" prospects plus leads) attributed to the Company have grown 45% to 6.2 Bboe from 4.3 Bboe of the best case in 2012, and the best case estimates of total gross Contingent Resources have grown 62% to 272 MMboe from 168 MMboe of the best case total Contingent Resources estimated in 2012.

José Francisco Arata, President of the Company commented:

"The 2014 certified Resource Report illustrates the Company's continued success in growing and expanding its resource portfolio in Latin America. Access to a large and diversified resource base feeds future reserves growth which in turn provides the future production of a successful E&P Company like Pacific Rubiales."

Highlights on the best case estimates of gross unrisked Prospective Resources and gross Contingent Resources:

  • 6,240 MMboe of total Prospective Resources (including 1,392 MMboe in prospects plus 4,848 MMboe in leads), representing an increase of 45% compared to the 2012 evaluation.
  • The total Prospective Resources are contained in 166 opportunities (82 prospects and 84 leads) on 36 evaluated blocks in six countries.
  • The total Prospective Resources are estimated to include 5,805 MMbbl of oil and natural gas liquids (93%), and 2.6 Tcf (435 MMboe) of natural gas (7%).
  • 22% or 1,392 MMboe (63% light and medium oil, 27% heavy oil, 10% natural gas) of the total Prospective Resources are in prospects, an increase of 7% from 1,302 MMboe in 2012.
  • 78% or 4,848 MMboe (79% light and medium oil, 15% heavy oil, 6% natural gas) of the total Prospective Resources are in leads, a 62% increase from 2,989 MMboe in 2012, largely reflecting new exploration blocks acquired in 2013 and new leads defined on seismic surveys.
  • 40% of the total Prospective Resources opportunities are in Peru, 25% in Colombia, 21% in Guyana, 12% in Brazil, 1% in Papua New Guinea and 1% in Guatemala.
  • 272 MMboe of total gross Contingent Resources, a 62% increase from 168 MMboe in 2012, mainly due to acquisitions and advancement from Prospective Resources through successful exploration drilling.

Contingent Resources

The best case estimate of total gross Contingent Resources is 272 MMboe (low case estimate of 35 MMboe, high case estimate of 584 MMboe, and a Pmean case of 256 MMboe). Approximately 61% or 165 MMboe of these resources are in Peru with the bulk in Block Z-1 (estimated to contain 893 Bcf or 159 MMboe of natural gas) and 7 MMbbl (light and medium oil) in Block 126. Additional Contingent Resources are in blocks CPO-17 in Colombia (80 MMbbl of heavy oil), in the Karoon blocks in the Santos basin Brazil (24 MMbbl light and medium oil), with the remainder in the PPL-237 Block in PNG (2.4 MMboe comprised of approximately 13 Bcf of natural gas and 0.3 MMbbl of natural gas liquids).

Cautionary Note Concerning Forward-Looking Statements

This press release contains forward-looking statements. All statements, other than statements of historical fact, that address activities, events or developments that the Company believes, expects or anticipates will or may occur in the future (including, without limitation, statements regarding estimates and/or assumptions in respect of resource estimates, potential resources and reserves and the Company's exploration and development plans and objectives) are forward-looking statements. These forward-looking statements reflect the current expectations or beliefs of the Company based on information currently available to the Company. Forward-looking statements are subject to a number of risks and uncertainties that may cause the actual results of the Company to differ materially from those discussed in the forward-looking statements, and even if such actual results are realized or substantially realized, there can be no assurance that they will have the expected consequences to, or effects on, the Company. 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, Peru, Guatemala, Brazil, Papua New Guinea or 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; the impact of environmental, aboriginal or other claims and the delays such claims may cause in the expected development plans of the Company 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. Any forward-looking statement speaks only as of the date on which it is made and, except as may be required by applicable securities laws, the company disclaims any intent or obligation to update any forward-looking statement, whether as a result of new information, future events or results or otherwise. 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.

Boe Conversion

The term "boe" is used in this news release.  Boe may be misleading, particularly if used in isolation. For example 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.

For all natural gas resources in Colombia, boe's have been expressed using the Colombian conversion standard of 5.7 Mcf:  1 bbl required by the Colombian Ministry of Mines and Energy, and for all natural gas Resources in Peru, boe's have been expressed using the Peruvian conversion standard of 5.626 Mcf: 1 bbl required by Perupetro S.A.   The boe in Papua New Guinea and Guyana is converted at 6 Mcf: 1 bbl.

Statements related to resources are deemed forward-looking statements as they involve the implied evaluation, based on certain estimates and assumptions that the resources will be discovered (in the case of Prospective Resources) and can be profitably produced in the future. Specifically, forward-looking information contained herein regarding "resources" may include: estimated volumes and value of the Company's oil and gas resources; estimated volumes of Contingent and Prospective Resources and the ability to finance future development; and, the conversion of a portion of Contingent Resources into reserves and Prospective Resources into Contingent Resources.

Resources

Readers should give attention to the estimates of individual classes of resources and appreciate the differing probabilities of recovery associated with each class. Estimates of remaining recoverable resources (unrisked) include Prospective resources that have not been adjusted for risk based on the chance of discovery or the chance of development and Contingent resources that have not been adjusted for risk based on the chance of development. It is not an estimate of volumes that may be recovered. Actual recovery is likely to be less and may be substantially less or zero.

Prospective Resources are those quantities of oil and gas estimated to be potentially recoverable from undiscovered accumulations. There is no certainty that the Prospective Resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the Prospective Resources. Application of any geological and economic chance factor does not equate Prospective Resources to Contingent Resources or reserves. In addition, the following mutually exclusive Classification of Resources were used:

  • Low Estimate - This is considered to be a conservative estimate of the quantity that will actually be recovered from the accumulation. This term reflects a P90 confidence level where there is a 90% chance that a successful discovery will be equal to more than this resources estimate.

  • Best Estimate - This is considered to be the best estimate of the quantity that will actually be recovered from the accumulation. This term is a measure of central tendency of the uncertainty distribution and in this case reflects a 50% confidence level where there is a 50% chance that the successful discovery will be equal to or more than this resources estimate.

  • High Estimate - This is considered to be an optimistic estimate of the quantity that will actually be recovered from the accumulation. This term reflects a P10 confidence level where there is a 10% chance that the successful discovery will be equal to or more than this resources estimate.

  • Pmean Estimate - This is determined using the arithmetic average of the low, best and high case estimates relating to the reservoir volumes, reservoir properties and recovery factors.

Contingent Resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingent Resources have an associated chance of development (economic, regulatory, market and facility, corporate commitment or political risks). The estimates herein have not been risked for the chance of development. There is no certainty that the Contingent Resources will be developed and, if they are developed, there is no certainty as to the timing of such development or that it will be commercially viable to produce any portion of the Contingent Resources.

In this press release total volumes of resources have been expressed for high case estimates, low case estimates, best case and Pmean estimates for both Contingent and Prospective Resources. All estimates of Prospective and Contingent Resources are expressed in gross (WI before royalties) volumes as most royalties payable to the Governments of the various countries in the evaluation are sliding scale and it is not possible to estimate net (WI after royalties) volumes without appropriate production forecasts. The total volumes are arithmetic sums of multiple estimates of Contingent and Prospective Resources, as the case may be, which statistical principles indicate may be misleading as to volumes that may actually be recovered. Readers should give attention to the estimates of individual classes of resources and appreciate the differing probabilities of recovery associated with each class as explained in this section.
