Pacific Rubiales Provides Second Quarter 2015 Operational Update

TORONTO, July 15, 2015  - Pacific Rubiales Energy Corp. (TSX:PRE.TO) (BVC:PREC) today provided an operational update for its second quarter 2015 operating results, which includes estimates of production and sales volumes, price realizations, and operating netbacks, summarized as follows:

Second Quarter 2015 Results

Total net production for the quarter is expected to be in the range of 151 to 153 Mboe/d, approximately 2% higher than the same period a year ago. This is in-line with the previous quarter, despite the increased pipeline transportation disruptions through the quarter.

The Company reports its sales volumes comprised of produced volumes available for sale, plus purchased diluent volumes (mixed with heavy oil production to form a sales blend), plus oil for trading ("OFT") volumes, plus/minus sales inventory adjustments. Sales volumes can vary significantly from quarter-to-quarter as a consequence of fluctuating diluent and OFT volumes, and significant swings in oil inventories, which are related to the timing of export cargo liftings.

Sales volumes in the second quarter are expected to be in the range of 143 to 146 Mboe/d, a decrease of approximately 7% from the same period a year ago. The OFT volumes are expected to be in the range of 10 to 12 Mbbl/d (compared to 15.5 Mbbl/d in the first quarter 2015). Volumes acquired for dilution were approximately 600 bbl/d (compared to 325 bbl/d in the first quarter 2015).

The Company expects combined realized prices (including natural gas production) in the second quarter to be in the range of $52 to $55 /boe, which is lower as compared to the same quarter a year ago, but in-line with the decline in benchmark prices in 2015. Most of the Company's oil production in Colombia and Peru is exported at prices linked to international oil prices. Both WTI and Brent benchmark oil prices increased approximately 17% (~US$9/bbl) during the quarter.

The decline in global oil prices over the past quarters is partly offset by the cost reductions the Company has been able to achieve in 2015. The Company expects underlying operating cost (including production, transportation and diluent cost) in the second quarter to be in the range of $23 to $26 /boe, which is lower as compared to the same quarter a year ago and slightly higher than the first quarter 2015 as a result of lower sales volumes and a fluctuating Colombian Peso against the U.S. Dollar. The decrease in production costs is sustainable and mainly attributed to the Company's ongoing cost reduction programs. Transportation and diluent costs was comparable to the first quarter of 2015 on a boe basis.

Operating netbacks for the quarter are expected to be higher compared with the prior quarter, impacted by an increase in benchmark oil prices and lower operating costs. Cash operating margins are expected to be approximately 58%. The Company calculates its operating netback for both revenues and costs based on total sales volumes excluding OFT volumes, rather than produced volumes. Note that the adjusted EBITDA margin on OFT volumes is typically $1 to $3/bbl. Total operating costs are reported as a combination of: production, transportation, and diluent costs, plus other costs and overlift/underlift costs. The latter two (other costs and overlift/underlift) largely relate to movements in storage and cargo lifting inventory and can consequently significantly impact total costs either positively or negatively, in any given quarter. This is evident by the significant overlift in the first quarter of 2015 and an underlift in the first quarter of 2014.

General and administrative costs for the quarter are expected to be in the range of $4.00 to $5.00 /boe, a decrease of approximately 29% from the same period a year ago. This is approximately 33% higher than the previous quarter as the significant cost-cutting measures implemented were offset by lower sales volumes.

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, Guyana and Mexico; 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 17, 2015 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.

In addition, reported production levels may not be reflective of sustainable production rates and future production rates may differ materially from the production rates reflected in this press release due to, among other factors, difficulties or interruptions encountered during the production of hydrocarbons.

Unaudited Financial Information

Certain financial and operating results included in this news release such as capital expenditures, production information and operating costs are based on unaudited estimated results. These estimated results are subject to change upon the Company releases the unaudited interim consolidated financial statements for the period ended March 31, 2015, and changes could be material.

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.
