2007 Year-end Update: Key Messages

Significant investment in people, infrastructure and drilling during 2007 has established the foundation for future growth in production, reserves and value.

New reserves evaluation by D&M demonstrates the success of GEOPARKs technical team since the IPO.

2007 production reached 2,300 boepd at year-end, below expectations. However, reservoir studies conducted over the past 6 months give greater confidence in future growth. Current production is approximately 2,830 boepd net.

New long term gas sales contract secures the long term commercial development of the Fell Block in Chile.

GEOPARK has an ambitious US$57MM capex programme planned for 2008 encompassing 17-20 new wells and new facility construction primarily focused on Fell Block.

Tranquilo Block acquisition doubles net acreage position in Chile providing new avenues for organic growth and enhancing GEOPARKs leading position in Chile.

Net revenue increased 83% to US$11M in 2007.

Despite a 6 month delay in the start-up of the drilling program due to the late arrival of the drilling rig, oil and gas production in Chile and Argentina increased by 56% from approximately 1,470 barrels of oil per day equivalent (boepd) in January 2007 to approximately 2,300 boepd at the end of December 2007 .

GEOPARK benefited from stronger oil and gas prices resulting from contract renegotiations and market factors.

2007 Exploration costs includes US$4,5M of write off of dry wells.

Administrative and other operating cost include US$4M of shares awards and stock option plan granted to employees in 2006 at IPO (US$2.5M in 2006).

Financial income includes US$1.0M of exchange gains in Chile and US$0,9M of interest earned on cash balances.

Financial expenses arise mainly from interest losses (US$1.8MM) and exchange rate losses in Argentina.

D&M preliminary report reflect a migration of contingent resources into P3 reserves

Improved well performance by reservoir stimulation and further appraisal drilling has the potential to migrate P3 reserves to P1 and P2 categories

Reservoir studies and stimulation testing are underway with results expected during 2008

Additional contingent resources added to the south

Original MOU signed by both parties in Q1 2007

Alliance involves 4 main components:

Long term (10 years) gas supply contract. Term Sheet signed October 2007.

New gas price formula resulting in more advantageous pricing of gas for GEOPARK and a volume bonus directly linked to volumes above 18 mmcfd. Gas price over US$5/mcf achieved in Q1 2008. New price positively impacts reserve volumes and valuations

Gas Pre-Sale Agreement: US$ 40 million of gas to be sold in advance

Strategic partnership to acquire new blocks for gas exploration in Chile

The Methanex Agreement substantially de-risks exploration for gas on the Fell Block and financially underpins GEOPARKs medium term exploration and development activities

Methanex Strategic Alliance

18

Conclusions

GEOPARK intends to aggressively explore, appraise and develop its highly prospective acreage in Chile. This will involve a 17-20 well drilling programme with a capex of US$57 million.

Management is actively pursuing a solution to the reservoir performance issue which has so far constrained gas production in the Santiago Norte Grande accumulation in the Fell Block. Resolution of this issue is expected to have important implications for reserves and production during the next 12 months.

The recent acquisition of a 30% working interest in the high potential Tranquilo block (and operatorship) doubles GEOPARKs net acreage position in Chile.

SPEED

Safety, Prosperity, Employees, Environment and CommunityDevelopment

Our long term success in creating value is enhanced and measured by our collective achievement in each of these areas.

Safety Creating a safe and organized workplace ensuring that everyone returns home from work everyday without injury

Prosperity Performing with effort, quality and beyond our commitments to continuously build market value. Only a financially healthy company can provide benefits for others

Employees Providing the opportunity for employees to grow professionally, contribute and share in the success of the company

Environment - Leaving the environment in the same or better natural condition than when it was encountered

Community Respecting and protecting the region, laws, customs and people where we work and creating real and sustainable opportunities and benefits for the local communities
