GeoPark Announces Independent Exploration Potential Evaluation of Latin American Portfolio of 770 Million - 1.5 Billion BOE

SANTIAGO, Chile, July 6, 2015 /PRNewswire/ -- GeoPark Limited ("GeoPark") (NYSE: GPRK), the Latin American oil and gas explorer, operator and consolidator with operations and producing properties in Colombia, Chile, Brazil, Argentina and Peru^[1], announced today the results of an independent audit of the Company's exploration resources as of December 31, 2014, prepared by Gaffney, Cline & Associates ("GCA").

GeoPark has interests in 31 blocks, covering over six million acres, in 12 proven hydrocarbon basins, in five Latin American countries, with a risk-balanced mix of production, development, exploration and unconventional resource opportunities. GeoPark's current production is approximately 19,500 BOEPD and oil and gas reserves (including Peru), as of December 31, 2014 certified by DeGolyer & MacNaughton, include proven (P1) reserves of 63 MMBOE, proven and probable (2P) reserves of 122 MMBOE, and proven, probable and possible reserves (3P) of 221 MMBOE. DeGolyer & MacNaughton has estimated the Net Present Value (NPV10) of GeoPark's 2P reserves to be $1.7 Billion (using a forward oil price curve beginning at $50 per barrel for 2015).

GCA's audit was focused on the evaluation of new prospective exploration resources covering 98% of GeoPark's total exploration resources beyond its known and certified oil and gas proven, probable and possible reserves.

Year End 2014 Exploration Resource Audit Highlights

• 768 to 1,465 MMBOE of total exploration resources (including 220 to 597 MMBOE in unconventional oil resources)
• Total exploration resources are contained in 148 opportunities (112 prospects, 30 leads, 4 plays and 2 unconventional projects) on 31 evaluated blocks in five countries
• Total exploration resources (best case) include 634 MMbbl of oil (94%) and 251 BCF (42 MMBOE) of natural gas (6%)
• 38% or 257 MMBOE of the total conventional exploration resources (best case) are in prospects and 35% or 238 MMBOE are in leads and plays. Unconventional resources represent 27% or 181 MMBOE of the Company's total exploration resources

Commenting, James F. Park, CEO of GeoPark, said: "This exploration resource estimate confirms the extent, depth and potential of GeoPark's in-house project inventory and the running room we have for continued organic growth. In addition to our already-discovered and significant oil and gas reserve base (with 2P reserves over 122 million BOE), we own a big mix of assets with the potential for finding 770 million to 1.5 billion BOE of new oil and gas reserves. These represent attractive assets, located in proven hydrocarbon basins with existing infrastructure, and which are managed by GeoPark's geoscience and operations team, with our 70+% drilling success rate since 2008 and consistent nine year growth track record."

2014 Year End Resources Summary

GeoPark engaged GCA to prepare an independent resource audit of GeoPark's exploration properties as of December 31, 2014. The audit covered 98% of GeoPark's total exploration opportunities.

The table below represents the low, best, high and mean total oil and gas resources by country at GeoPark's Working Interest (WI) as of December 31, 2014:

Further detail is provided in the attached Appendix.

(*) Unconventional includes shale oil resources in Fell Block and in Campanario Block. In case the Estratos con Favrella unconventional shale oil resources (Fell Block) prove to be commercial, the range of the final oil recovery factor assumed by GeoPark's management for the calculation above considers: Low: 0.8%, Best: 1.26%, High: 2%, and Mean: 1.35%. The GCA audit did not cover the above recovery factors and only included an evaluation of original oil in place.

Readers are cautioned that the exploration resources disclosed in this press release are not necessarily indicative of long term performance or of ultimate recovery. Unrisked prospective resources are not risked for change of development or chance of discovery. If a discovery is made, there is no certainty that it will be developed or, if it is developed, there is no certainty as to the timing of such development. In this news release risked prospective resources have been risked for chance of discovery but have not been risked for chance of development. If a discovery is made, there is no certainty that it will be developed or, if it is developed, there is no certainty as to the timing of such development.

The accuracy of any resource estimate is a function of the quality of the available data and of engineering and geological interpretation.  Results of drilling, testing and production that postdate the preparation of the estimates may justify revisions, some or all of which may be material.  Accordingly, resource estimates are often different from the quantities of oil and gas that are ultimately recovered, and the timing and cost of those volumes that are recovered may vary from that assumed

The following classification of resources was used:

• Low Estimate means there is at least a 90 percent probability (P90) that the quantities actually recovered will equal or exceed the low estimate.
• Best Estimate means there is at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate.
• High Estimate means there is at least a 10 percent probability (P10) that the quantities actually recovered will equal or exceed the high estimate.
• Mean is the mean field size or arithmetic average estimate of the quantities that will actually be recovered.

Prospective Resources are those quantities of petroleum that are estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects.  Prospective Resources have both an associated "chance of discovery" and a "chance of development" (per PRMS).  Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates, assuming their discovery and development, and may be sub-classified based on project maturity. 

There is no certainty that any portion of the Prospective Resources will be discovered.  If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources.  Prospective Resource volumes are presented as unrisked.  The risk or chance of finding a minimum hydrocarbon volume that can flow to surface is presented as Geological Chance of Success (GCoS).

Rounding amounts and percentages: Certain amounts and percentages included in this press release have been rounded for ease of presentation. Percentage figures included in this press release have not in all cases been calculated on the basis of such rounded figures, but on the basis of such amounts prior to rounding. For this reason, certain percentage amounts in this press release may vary from those obtained by performing the same calculations using the figures in the financial statements. In addition, certain other amounts that appear in this press release may not sum due to rounding.
