Geographical Segment Reporting

The Company divides ¡ts business into four geographical segments-Chile, Colombia, Brazil and
Argentina-that correspond to its principal jurisdictions of operation. Activities not falling into these
four geographical segments are reported under a separate corporate segment that primarily
includes certain corporate administrative costs not attributable to another segment. For the six
month period ended June 30, 2013, the Chilean segment contributed US$82.9 million, or 51.5%, of
GeoPark revenues, the Colombian segment contributed US$77.2 million, or 48.0%, of revenues and
the Argentine segment contributed US$0.7 million, or 0.5%, of revenues.

In the description of results of operations that follows, the “Other” operations reflect non-Chilean
and non-Colombian operations, primarily consisting of Argentine, Brazilian and corporate head
office operations.

In 2012 the Company has accounted for the results of its operations in Colombia since the
acquisition dates which occurred during the first quarter of 2012. Including the Colombian
acquisitions on a proforma basis (i.e. for the whole of the first quarter), Revenues and Adjusted
EBITDA would have been US$24 million and US$8 million higher during the first quarter of 2012,
respectively.

The following table summarizes certain financial and operating data.

Net revenue increased 31.8% to US$160.8 million (1H 2013: US$122.0 million)
The increase in net revenue is explained by:

e An iincrease of US$60.6 million in oil deliveries

e Aniincrease of US$1.9 million from the realized price for gas sold;

partially offset by:

e A decrease of US$8.1 million in gas deliveries, and
e A decrease of US$15.6 million from the realized price for oil sold.

Net revenue attributable to the operations in Chile decreased by 2.9% to US$82.9 million,
representing 51.5% of total consolidated revenues (1H2012: US$85.3 million; 69.9% of total
consolidated revenues).

Sales of crude oil increased by 16.4% to 883 mbbl (1H2012: 758 mbbl), mainly due to new
discoveries in Tobifera formation. This was partially offset by (i) a decrease in the average realized
prices per barrel of crude oil of US$8.2 per barrel, or 9.1%, to US$81.4 per barrel (1H2012:
US$89.6 per barrel), of which US$2.8 per barrel was attributable to oil quality discounts and the
remaining to WTI variation, and (ii) a reduction in Chilean gas sales in an amount of US$6.1
million, or 35.7%, to US$11.0 million (1H 2012: US$17.1 million). The lower gas sales resulted
from reduced drilling activity for gas prospects, as we focused on oil prospects and the temporary
shutdown in the Methanex Plant, where GeoPark delivers its gas. During the shutdown, which
started at the end of April 2013, the Company delivered to Methanex a reduced volume of gas of
approximately of 11.5 mmcfpd. The Company has been informed by Methanex that the plant will
reassume activities by the end of September 2013.

Net revenue attributable to the operations in Colombia was US$77.2 million, representing 48.0% of
total consolidated revenues (1H2012: US$36.0 million; 29.5% of total consolidated revenues).

GeoPark Results

Sales of crude oil increased by 199% to 906 mbbl (1H2012: 303 mbbl), due to the development of
the Max and Tua fields and the discoveries of the Tarotaro and Potrillo fields. This was partially
offset by a decrease in the average realized prices per barrel of crude oil from US$107.9 per barrel
to US$79.7 primarily as a result of a change in the Company’s commercial strategy whereby the
Company had been historically delivering all its Colombian production at Coveñas, while in 2013 the
Company started selling part of its production at the wellhead. Consequently the selling price has
been reduced and the transportation costs (Selling Expenses) have been reduced by a similar
amount. In addition the Vasconia marker decreased 32% in 1H 2013 in respect of 1H2012.

Production costs increased 48% to US$81.1 million (1H2012: US$54.7 million), primarily as the
result of the incorporation of full six months of the Colombian operations into the Company’s
results, which resulted in revenue mix to be 93.2% oil and 6.8% gas.

Operating costs per boe increased to US$10.5 per boe (1H2012: US$8.1 per boe). This increase
was driven by an increase in well and facilities maintenance, primarily pulling costs increase of
US$1.5 million recorded therein and the continuing change in revenue mix (particularly influenced
by the Methanex shutdown) from gas to oil, which has higher production costs than gas. In the first
six months of 2013, the revenue mix for Chile was 87% oil and 13% gas, whereas for the same
period in 2012 it was 80% oil and 20% gas.

Operating costs in Colombia increased 106% primarily due to the increase in production. However,
operating costs per boe in Colombia decreased to US$24.7 per boe (1H2012: US$36.6 per boe),
with the increased production resulting in a dilution of fixed costs.

well in the Fell Block for US$3.6 million, one well in the Tranquilo Block for US$1.1 million, seismic
and others in Otway Block for US$ 4.1 million, and three wells in Colombia for US$3.0 million), as
compared to US$8.5 million (two wells in the Fell Block for US$5.9 million and drilling costs
associated to four wells in Colombia for US$ 2.6 million) in such write-offs in the same period in

sales in Colombia taking place at wellhead, which reduces transportation costs but also reduces
selling prices for similar amounts. Lower prices offset higher volumes sold. In the Chilean
operations, selling expenses were 6% lower compared to the same period of the prior year. In 2012
in Chile selling expenses included penalties associated with the ‘deliver or pay” clauses in the gas
sales agreement.

Net Financial Results

Financial loss increased 180% to US$20.6 million (1H2012: US$ 7.3 million), due to the accelerated
amortization of debt issuance costs incurred in connection with the redemption of the Notes due
2015 in an amount of US$8.6 million following the issuance of the Notes due 2020 in the six-month
period ended June 30, 2013, the incorporation of a full six months of Colombian operations in the

Profit before income tax decreased by 41% to US$21.3 million (1H2012: US$36.2 million),
primarily influenced by the occurrence of two non-recurring items: (1) accelerated amortization of
debt issuance costs described above for US$8.6 million; and (2) a bargain purchase gain on
acquisition of subsidiaries of US$8.4 million as a result of the acquisitions of Winchester and Luna
registered in the six-month period ended June 30, 2012.

Income tax decreased 35% to US$7.1 million (142012: US$10.9 million). The effective tax rate
was 33% (1H2012: 30%). The effective tax rate was influenced by the incorporation of full six
months of the Colombian operations in GeoPark’s results, which are subject to a higher tax rate
than the other operations, and the non-recurring tax exempted bargain purchase gain on
acquisition of subsidiaries.

Average net production increased 12% to 13,020 (boepd) for 2Q 2013. In Colombia, total oil
production increased 99.5% to 6,157 bopd and in Chile, total oil production increased 11.8% to
4,595 bopd. The gas production in Chile decreased 50% to 13,248 mcfpd. The lower gas production
resulted from reduced drilling activity for gas prospects, as the drilling activities were focused on oil

prospects and the temporary shutdown in the Methanex Plant.

GeoPark Results

Partially offset by:
. A decrease of US$4.8 million in gas deliveries, and

. A decrease of US$12.0 million from the realized sales prices for oil sold primarily as a result
of the change in the commercial strategy whereby the Company had been historically
delivering all its Colombian production at Coveñas, while in 2013 the Company started
selling part of its production at the wellhead. Consequently the selling price has been
reduced and the transportation costs (Selling Expenses) have been reduced by a similar
amount.

Production Costs

Other 1,140 246 894 363%
Total 42,834 35,306 7.528 21%

Production costs were 21% higher in 2Q 2013 compared to 2Q 2012. The main driver for this
increase was the increase in oil production of 49%.

In Chile, operating costs (production costs less depreciation and royalties) per boe increased 35%
to US$ 10.7 per boe (2Q2012: US$ 7.9 per boe). This increase was driven by an increase in well
and facilities maintenance, primarily pulling costs and the continuing change in revenue mix from
gas to oil, which has higher production costs than gas.

In Colombia, operating expenditures per boe decreased 31% to US$ 25.1 per boe (2Q2012: US$
36.3 per boe), due to an increase in production which resulted in a dilution of fixed costs.

Total 34,362 36,021 (1,659) -5%

Adjusted EBITDA decreased 5% or US$ 1.7 million as consequence of a reduction of US$ 3.4 million
in the Chilean Adjusted EBITDA influenced by lower gas sales and the startup of the Tierra del
Fuego operations and an increase of US$ 1.9 million related to corporate expenses (mainly higher
costs associated with new business developments) and the start-up of Brazilian operations. Both
effects were partially offset by an increase of US$ 3.7 million in the Colombian Adjusted EBITDA.

STRATEGIC HIGHLIGHTS

Risk-Balanced Entry into Brazil

1)

2)

Acquisition of Interest in Manati Producing Gas Field

On May 15, 2013, GeoPark announced it had agreed to acquire Rio das Contas, which holds a
10% working interest in the shallow-depth offshore Manati Field in the Camamu-Almada Basin,
from Panoro Energy for a total cash consideration of US$140.0 million, subject to certain
purchase price and easement adjustments. The Manati Field, which is operated by Petrobras,
the Brazilian national company, is the largest non-associated gas field in Brazil and produces
approximately 9% of the gas produced in Brazil. During the year ended December 31, 2012
and the second quarter of 2013, net production to Rio das Contas was approximately 3,677
boepd and 3,884 boepd, respectively, from the Manati Field. In the year ended December 31,
2012, Rio das Contas generated net income of approximately US$23.2 million and revenues of
approximately US$51.1 million.

The Rio das Contas acquisition will provide GeoPark with a long-term off-take contract with
Petrobras that covers approximately 75% of net proved gas reserves in the Manati Field, a
valuable relationship with Petrobras and an established geoscience and administrative team to
manage the assets and to seek new growth opportunities.

The closing of the acquisition is subject to certain conditions, including approval by the Brazilian
National Petroleum, Natural Gas and Biofuels Agency (“ANP”) and the Brazilian antitrust
authorities. This is expected to occur during the second half of 2013.

Award of Seven Exploration Licenses

On May 15, 2013, following an invitation for bids from the ANP, GeoPark announced it had
been awarded, in an international bidding round, seven new concessions in Brazil, in the
following basins:

e Recóncavo Basin in the State of Bahia: REC-T 94 and REC-T 85 Concessions; and

+ Potiguar Basin in the State of Rio Grande do Norte: POT-T 664, POT-T 665, POT-T 619,
POT-T 620 and POT-T 663Concessions.

GeoPark’s winning bids are subject to confirmation of approval requirements and entry into
concession agreements with the ANP, which is expected to occur in 3Q2013. GeoPark has
committed to invest a minimum of US$ 15.3 million (including bonuses and work program)
during the first three years of the exploratory period. The new concessions cover an area of
approximately 54,850 gross acres.
