Commenting, James F. Park, CEO of GeoPark, said: “With solid fourth quarter results, GeoPark has
completed another successful year of record operational and financial growth, proven execution, and
strategic positioning to open future opportunities. For the seventh consecutive year, key performance
indicators of production, reserves and cash flow recorded important gains – and we further expanded our
business platform into major hydrocarbon regions in Latin America. Our asset base now consists of 29 blocks
in ten hydrocarbon basins in four countries with a rich mix of exploration, development, production, and
unconventional resource opportunities and supported by a current production of over 20,000 boepd and
reserves of 70 million boe (2P).

Our Chile business continues to build value with increased oil production (up 14%) from our successful
drilling program in the Tobifera formation on the Fell Block. On our new Tierra del Fuego acreage across the
Magellan Strait (similar geological play as the Fell Block), we just completed a 1,500 sqkm 3D seismic
survey, put a new gas field discovery on production and initiated a continuous 15-17 exploration and
development well drilling program.

Our Colombia business, in our first full year,
continued on a high growth trajectory with
bottom-line production and reserve
improvements; up 89% and 45%

NT respectively. Block Llanos 34, operated by
GeoPark, led the charge with four new oil field
discoveries – and, we are now carrying out an
18-23 well drilling program to develop these
fields and to explore new prospects on our
Colombian assets.

We established a Brazil business in 2013,
following our risk-balanced approach, by
assembling an asset portfolio (ten blocks
through an acquisition and two competitive

; bidding rounds) with secure production and
ida E cash flow, attractive exploration potential and
poros a partnership with Petrobras. We also
acquired an experienced Brazilian technical
team to manage our assets and further
expand in Brazil – one of the world’s highest-
potential hydrocarbon countries.

Our balance sheet was strengthened during
2013 with a successful placing (substantially
over-subscribed) of a $300 million
international bond. We have cash on hand
oa Pa PA, and our Adjusted EBITDA has continued to
grow (up 38%) to support our organic
investment program. In early 2014, we made
an important transition to the New York Stock
Exchange – not only raising funds
(approximately $100 million) for our

expansion but also reaching a wider audience of investors to join us on our journey forward.

We continue to invest in building our team and know-how and believe this has created a differentiating
capability. We have strong technical, operating and financial teams in each country of operation supported
by a seasoned corporate team. Our biggest strength remains a team united by a culture of commitment,
hard work and heart.

We see Latin America as a region of unusual opportunity and are excited about expanding our footprint in
the countries where we currently have operations – as well as establishing a platform in Peru. Our focus is to
continue to build a balanced portfolio with lower-risk cash-flow generating properties, mid-term
development projects and longer term assets with attractive upside potential – working with our strategic
partners including LG, Tecpetrol and the IFC.

We are on target to continue our strong and steady 15-20% growth pace for 2014 – supported by a self-
funded $220-250 million work program – including the drilling of 50-60 new wells, balanced between
exploration (40%) and development (60%) targets and approximately between Chile (60%), Colombia
(35%) and Brazil (5%). This is a largely discretionary program and can be adjusted to accommodate new
opportunities or needs.

Our consistent operational and financial track record, supported by our 2013 results, and our outlook for
2014 give us the confidence to reach our objective of building the premier upstream independent company
in Latin America.”

CONSOLIDATED OPERATING PERFORMANCE

Production: Consolidated production increased by 37% in 4Q2013 to 14,548 boepd. This growth was led
by 50% increase in consolidated oil production, mainly coming from higher oil production in the Colombian
operations. In addition, gas production decreased by 3% to 15,662 mcfpd.

Net Revenue: Consolidated net revenues increased by 29% to $87.8 million in 4Q2013.

Consolidated Oil Revenues: Consolidated oil revenues increased by 27% to $80.2 million in 402013 mainly
resulting from increased production, partially offset by an 8% decrease in the average realized price of oil
per barrel to $80.3.

Consolidated oil revenues represented 91% of total revenues in 4Q2013 (93% in 4Q2012).

Consolidated Gas Revenues: Consolidated gas revenues increased by 50% to $7.6 million in 4Q2013 mainly
due to higher average realized sales prices, partially offset by the slight decrease in gas production. The

average realized gas sales price increased 47% to $5.8 per mcf in 4Q2013 vs. $4.0 per mcf in 4Q2012.

Gas revenues represented 9% of total revenues in 4Q2013 (7% in 4Q2012).

Costs: Consolidated production costs increased by 23% to $49.8 million in the 4Q2013, mainly resulting
from total increased production. Improved fixed cost absorption led production costs per barrel to decrease
10% from $41.6 per boe to $37.2 per boe.

Consolidated exploration costs decreased from $6.1 million in 402012 to $0.2 million in 4Q2013, primarily
as a result of lower write-offs in Chile (no exploratory wells expensed in 4Q2013).

Consolidated administrative costs increased by 84% to $14.5 million in 4Q2013, primarily as a result of (i)
increased staff costs, mainly in the Colombian operations and at the corporate level; (ii) higher costs related
to the start-up of the Brazilian operations; and (iii) new business costs.

Consolidated selling expenses decreased by 47% to $4.7 million in 402013, mainly driven by reductions in
Colombian selling expenses.

Adjusted EBITDA: Consolidated Adjusted EBITDA increased by 55% to $41.4 million in 402013. The
increase was mainly driven by higher production and revenues, partially offset by higher administrative
costs.

Consolidated Adjusted EBITDA per boe increased by 13% to $30.9 per barrel in 402013.

ANALYSIS BY BUSINESS SEGMENT

Operations in Chile

In Chile, GeoPark is the first and the largest non-state controlled oil and gas producer. Operations began in
2006 in the Fell Block and have evolved from having a non-operated, non-producing interest to a fully-
operated and producing asset with 45.1 mmboe of 2P PRMS reserves certified by DeGolyer and McNaughton
(“DEM”) as of December 31, 2013 and an average production of 6,748 boepd during the year. In addition,
the Company operates five other hydrocarbon blocks in Chile with significant prospective resources.

Key Indicators 4Q2013 4Q2012 % Chg.
Oil production (bopd) 4,160 3,879 7%
Gas production (mcfpd) 15,526 16,006 -3%
Average net production (boepd) 6,748 6,546 3%
Net Revenues ($ million) 38.1 32.7 17%
Adjusted EBITDA ($ million) 22.8 17.2 33%

Production: Production in Chile grew by 3% reaching 6,748 boepd and which included a 7% increase in oil
production. Oil production growth in Chile is mainly driven by development of fields producing from the
Tobifera formation in the Fell Block.

Net Revenue: Net revenue attributable to the operations in Chile increased by 17% to $38.1 million for
4Q2013, representing 43% of consolidated revenues, compared to 48% in 4Q2012.

Oil revenues increased by 11% to $30.5 million in 402013, due to higher production and higher average
realized oil price per barrel.

The average realized oil price increased by 8% to $86.1 per barrel in 402013, mainly attributable to an
increase of approximately 10% in average WTI prices.

Oil revenues represented 80% of total revenues in Chile in 402013, as compared to 84% in 4Q2012.

Gas revenues increased by 50% to $7.6 million in 492013 mainly due to an increase of 47% in the average
realized gas price resulting from higher world methanol prices and an improved agreement with the

Company’s gas purchaser, Methanex. Gas revenues represented 20% of total revenues in Chile in 4Q2013,
as compared to 16% in 4Q2012.

Costs: Production costs in Chile in 402013 increased by 5% to $17.8 million in 4Q2013, in line with
production growth in the quarter.

Exploration expenses in Chile amounted to $0.1 million in 4Q2013 compared to $6.0 million in 402012,
mainly due to lower write-offs.

Administrative costs in Chile in 4Q2013 decreased to $4.3 million from $4.5 million in 4Q2012. Selling
expenses in Chile decreased from $1.4 million in 402012 to $0.9 million in 4Q2013.

Adjusted EBITDA: Adjusted EBITDA in Chile increased by 33% to $22.8 million in 402013, mainly driven
by revenue growth.

Adjusted EBITDA per boe increased by 29% to $36.7 per boe in 4Q2013 ($28.5 per boe in 4Q2012) due to
higher average realized sales prices and a higher percentage of oil in the production mix.

Operational Performance:
+ Development well Cerro Sutlej 2 in the Fell Block (GeoPark operated with a 100% WI) drilled to a
depth of 10,390 ft and tested oil in the Tobifera formation. The well resulted productive and tested
125 bopd.
+ Development well Yagan Norte 2 on the Fell Block (GeoPark operated with a 100% WI) was installed
with an electrical submersible pump (first reported ESP in the Magellan Basin in Chile) and tested
560 bopd during the pilot program.

Operations in Colombia

In Colombia, following the acquisitions of Winchester, Luna and Cuerva in early 2012, GeoPark has working
interests in 10 hydrocarbon blocks. Average production for the year 2013 reached 7,725 boepd and as of
December 31, 2013, 2P PRMS reserves certified by DUM were 16.5 mmboe.

Key Indicators 4Q2013 4Q2012 % Chg.
Oil production (bopd) 7,717 4,018 92%
Gas production (mcfpd) 48 54 -11%
Average net production (boepd) 7,725 4,027 92%
Net Revenues ($ million) 49.3 35.6 38%
Adjusted EBITDA ($ million) 21.8 10.2 113%

Production: Colombian oil production increased by 92% to 7,717 bopd in 4Q2013, mainly as a result of
successful exploration and development efforts on Block Llanos 34 operated by GeoPark.

Net Revenue: Net revenues in Colombia increased by 38% to $49.3 million in 402013, mainly attributable
to increased oil production, partially offset by a decrease in the average realized price per barrel of crude oil.
The Colombian operations represented 56% of the total consolidated revenues as compared to 52% in
4Q2012.

The average realized price decreased by 16% to $77.4 per barrel in 4Q2013. During 2013, the Company
started selling part of its oil production at the well-head with higher commercial discounts, as opposed to
transporting it to different delivery points. This led to lower selling expenses that offset the lower selling
prices and had no impact in the overall Adjusted EBITDA.

Costs: Production costs in Colombia increased by 51% to $31.9 million in 402013, primarily due to the
increase in production. Improved fixed cost absorption led production cost per barrel to decrease 21% to
$44.8 per barrel.

Administrative costs in Colombia in 4Q2013 increased by 111% to $6.5 million compared to $3.1 million in
4Q2012, resulting mainly from increased staff and other costs related to the legal restructuring of the local
company organization.

Selling expenses in Colombia in 4Q2013 decreased by 50% to $3.7 million as explained above.

Adjusted EBITDA: Adjusted EBITDA in Colombia increased by 113% to $21.8 million in 402013, as
compared to $10.2 million in 402012, reflecting successful exploration and development operations.

Adjusted EBITDA per boe increased by 11% to $30.6 per boe in 4Q2013 vs. $27.6 per boe in 4Q2012,
influenced by lower production costs per boe resulting from increased efficiency.

Operational Performance:

e Exploratory well Aruco 1 on the Llanos 34 Block (GeoPark operated with a 45% WI), was drilled to a
depth of 10,705 ft and is currently under completion.

e Exploration well Tigana Sur 1 on the Llanos 34 Block (GeoPark operated with a 45% WTI), was drilled
to a depth of 12,113 ft in the Guadalupe formations and is currently producing approximately 1,390
bopd gross.

e Exploration well Tigana 1 on the Llanos 34 Block (GeoPark operated with a 45% WI) was drilled and
tested in the Mirador formation. The well is currently producing approximately 2,126 bopd gross of
20.2 degree API. In addition, the deeper Guadalupe formation was tested with a rate of
approximately 1,465 bopd gross.

Operations in Brazil

During 2013, GeoPark agreed to acquire Rio das Contas from Panoro Energy for a total cash payment of
$140.0 million, resulting in a 10% working interest for GeoPark in the BCAM 40 Concession, including the
shallow depth offshore Manati and Camaráo Norte Fields, in the Camamu Almada Basin in the State of
Bahia.

The Manati Field, which is in the production phase, is operated by Petrobras (with a 35% working interest),
in partnership with Queiroz Galváo Exploracáo e Producáo or QGEP (with a 45% working interest), and
Brasoil (with a 10% working interest). On March 26, 2014, the ANP approved the acquisition.

Additionally, the Company participated in the Bidding Rounds 11 and 12 organized by the ANP in Brazil in
2013, and was awarded nine new onshore concessions in the Reconcavo, Potiguar, Parnaiba and Sergipe-
Alagoas Basins. Two out of the nine concessions agreements are pending to be signed with the ANP.

GeoPark has continued to strengthen its technical team in Brazil and appointed Dimas Coelho, a former
exploration manager of Petrobras, to be Country Director.

In September 2013 the Company signed a strategic alliance with Tecpetrol to jointly identify and study and
potentially acquire upstream oil and gas opportunities in Brazil

Operations in Argentina

Operations in Argentina represented less than 1% of consolidated net revenues and 3% of consolidated
Adjusted EBITDA in 4Q2013.

In March 2014, GeoPark informed the Argentine Secretary of Energy of its decision to relinquish 100% of the
Cerro Doña Juana and Loma Cortaderal Concessions to the Mendoza Province. The area covered by those
blocks is 47.9 acres and neither the Cerro Doña Juana nor the Loma Cortaderal Blocks are currently in
production or have any associated reserves.

CONSOLIDATED NON-OPERATING RESULTS AND PROFIT FOR THE PERIOD

Net Financial Expenses: Net financial expenses increased to $6.7 million in 402013 from $2.7 million in
4Q2012, mainly due to higher debt as a result of the 2020 Bond issued for $300 million and which allowed
the Company to reduce its average cost of funding and extend maturities. This was partially offset by higher
interest income related to increased cash and cash equivalents.

Income Tax: Income tax amounted to $2.9 million in 402013 compared to $8.1 million in 402012. This
included the impact of the Colombian acquisitions in such year, partially offset by increased results in the
Chilean and Colombian operations in 4Q2013.

Profit: Profit increased to $9.7 million in 4Q2013, primarily due to increased operating profit in Chile and
Colombia.

BALANCE SHEET

GeoPark’s cash and cash equivalents at year end 2013 amounted to $121.1 million ($48.3 million at year
end 2012), mainly due to cash generation from operations during the year of $140.1 million along with
$164.0 million of funds generated from financing activities, mainly related to the 2020 Bond issued in
February, 2013, partially offset by $221.3 million of net cash used in the Company’s investment activities.

Total Assets as of December 31, 2013, amounted to $846.4 million. Additionally, total capital expenditures
for the year equaled $228.0 million and included $145.7 million in Chile, where the Company drilled 17 wells
and completed more than 1,100 sqkm of 3D seismic surveys, mainly related to the blocks located in Tierra
del Fuego. In Colombia, capital expenditures amounted to $82.3 million and included drilling 22 wells and
over 250 sqkm of 3D seismic surveys.

At year-end 2013, GeoPark’s total financial debt amounted to $317.1 million, which included $300 million
related to the 2020 Bond issued in February 2013.

Shareholders’ Equity reached $366.0 million and included minority interests of $95.1 million, related to LG
International’s participation in the Chilean and Colombian operations. LG International and GeoPark have a
strategic alliance to build a portfolio of upstream assets across Latin America.

CONSOLIDATED OPERATING PERFORMANCE

Production: Consolidated production increased by 20% in 2013 to 13,517 boepd. Consolidated oil
production increased by 48% to 11,113 bopd during 2013, mainly driven by increased production in
Colombia. Consolidated gas production decreased by 37% to 14,419 mcfpd during 2013, mainly resulting
from reduced gas drilling activity and the temporary shutdown of the Methanex plant from April to
September 2013.

On a proforma basis, consolidated production grew to 17,098 boepd in 2013.

Net Revenue: Consolidated net revenue increased by 35% to $338.4 million for the year ended December
31, 2013, primarily driven by increased oil production.

Consolidated Oil Revenues: Consolidated oil revenues increased by 42% to $315.4 million for the year ended
December 31, 2013, mainly resulting from increased production, partially offset by a decrease in the
average realized price of oil per barrel.

The average realized sales price decreased 10% to $81.9 per barrel in the year ended December 31, 2013.

Consolidated oil revenues represented 93% of total revenues in the year ended December 31, 2013 (88% in
the year ended December 31, 2012).

Consolidated Gas Revenues: Consolidated gas revenues decreased by 21% to $22.9 million in the year
ended December 31, 2013, mainly due to lower production, partially offset by higher average gas prices.

The average realized gas sales price increased 25% to $5.0 per mcf in the year ended December 31, 2013.

Consolidated gas revenues represented 7% of total revenues in the year ended December 31, 2013 (12% in
the year ended December 31, 2012).

Costs: Consolidated production costs increased by 39% to $179.6 million for the year ended December 31,
2013, mainly driven by the increase in production during the year, and impacted also by the higher
participation of the oil in the production mix, which has higher production costs than gas (oil production
increased by 48%). On the other hand, increased production generated improved fixed cost absorption,
which positively impacted the production costs per boe.

During 2013, the production mix was 82% oil and 18% gas, as compared with 66% oil and 34% gas for
2012.

Exploration costs decreased by 42% to $16.3 million for the year ended December 31, 2013, primarily
resulting from lower write-offs, with five wells charged to expense in 2013.

Administrative costs increased by 62% to $46.6 million in the year ended December 31, 2013. This increase
was primarily due to (i) higher corporate expenses related to the growth strategy of the Company and new
business efforts; (ii) increased staff and other costs in Colombia; and (iii) the start-up of operations in Tierra
del Fuego, Chile.

Selling expenses decreased by 30% to $17.3 million for the year ended December 31, 2013, primarily due
to the change in the selling point of oil in Colombia. In addition, in Chile selling expenses were 24% lower in
2013, primarily resulting from a 2012 delivery or pay penalty paid to Methanex.

Adjusted EBITDA: Adjusted EBITDA increased by 38% to $167.3 million in the year ended December 31,
2013.

Adjusted EBITDA per boe increased by 9% to $33.9 per boe in the year ended December 31, 2013 ($31.1
per boe in the year ended December 31, 2012).

As a reference, Adjusted EBITDA for the year ended December 31, 2013, corresponding to Rio das Contas
(the acquired interest in the Manati field in Brazil) amounted to $31.0 million (unaudited). This amount is
not included in the $167.3 million of Consolidated Adjusted EBITDA reported for the year 2013.

CONSOLIDATED NON-OPERATING RESULTS AND PROFIT FOR THE PERIOD

Net Financial Expenses: Financial expenses increased from $16.3 million in 2012 to $33.9 million for the
year ended December 31, 2013, due to (i) expenses incurred as part of the prepayment of the 2015 Reg S
Bond in February 2013, and (ii) higher debt related to the 2020 Bond issued in February, 2013. These were
partially offset by higher interest income related to increased cash and cash equivalents.

Income Tax: Income tax increased by 5% to $15.2 million for the year ended December 31, 2013.
GeoPark’s effective tax rate for the year 2013 was 30% as compared to 44% in 2012, due to lower losses
from deferred income taxes in 2013 mainly resulting from the effect of currency translation on tax base in
Colombia and Chile, compensated by an increase in current taxes resulting from higher profits in Chile and
Colombia.

Profit: Profit for the year increased by 89% to $34.9 million, as a result of higher operating results partly

offset by increased net financial expenses. Earnings per share increased by 79% to $0.50 per share for the
year ended December 31, 2013, mainly driven by increased profits in 2013.

2P PRMS reserves (without Brazil) grew by 8% to 61.6 mmboe, with a reserve replacement ratio of 199%,

for the year ended December 31, 2013, mainly resulting from new net additions of 9.6 mmboe related to
new discoveries in Chile and Colombia and reduced by 4.9 mmboe related to GeoPark’s 2013 production.
Including the reserves acquired in the Manati field (Brazil), 2P PRMS total reserves for 2013 increased by
23% to 70.2 mmboe.

CAUTIONARY STATEMENTS RELEVANT TO FORWARD-LOOKING INFORMATION

This press release contains statements that constitute forward-looking statements. Many of the forward
looking statements contained in this press release can be identified by the use of forward-looking words

such as “anticipate,” “believe,” “could,” “expect,” “should,” “plan,” “intend,” “will,” “estimate” and
“potential,” among others.

Forward-looking statements appear in a number of places in this press release and include, but are not
limited to, statements regarding the intent, belief or current expectations, regarding various matters,
including expected 2014 production growth and capital expenditures plan. Forward-looking statements are
based on management’s beliefs and assumptions and on information currently available to the management.
Such statements are subject to risks and uncertainties, and actual results may differ materially from those
expressed or implied in the forward-looking statements due to various factors.

Forward-looking statements speak only as of the date they are made, and the Company does not undertake

Information about oil and gas reserves: The SEC permits oil and gas companies, in their filings with
the SEC, to disclose only proved, probable and possible reserves that meet the SEC’s definitions for such
terms. GeoPark uses certain terms in this press release, such as “PRMS Reserves” that the SEC’s guidelines
do not permit GeoPark from including in filings with the SEC. As a result, the information in the Company’s
SEC filings with with respect to reserves will differ significantly from the information in this press release.
NPV10 for PRMS 1P, 2P and 3P reserves is not a substitute for the standardized measure of discounted
future net cash flows for SEC proved reserves.

Adjusted EBITDA is not an IFRS measure and it is possible that it may not be comparable with indicators
with the same name reported by other companies. Adjusted EBITDA should not be considered as a
substitute for operational profit of as a better measure of liquidity than operational cash flow, both of which
are calculated in accordance with IFRS.
