5 Industry Dynamics Over 50% of Top 50 oil companies are NOC’s (Source: Petroleum Intelligence Weekly) NOCs control as much as 94% of world’s oil and gas reserves (Source: Oil & Gas Journal, February 2, 2009) International projects are mostly targeting oil prospects, while U.S. projects generally focused on natural gas Technical advances such as 3-D seismic, hydraulic fracturing and horizontal drilling are bringing new activity in regions with known hydrocarbon systems U.S. shale plays still active and profitable with E&P expenditures expected to rise by 13% in 2010 Increasing demand for seabed seismic data acquisition (Transition Zone, Ocean Bottom Cable and 4D) 45% of companies surveyed by Barclays indicated an increase in 2010 exploration spending Source: Barclays Capital – The Original E&P Spending Survey , December 16, 2009.

7 Global Seismic Crew Count (Includes Onshore and Offshore) Seismic Crew Data Source: IHS Energy. * Counts for the CIS are based on partial data. There are an estimated 340 crews currently working in the CIS. Far East counts include only partial data for China and India. International seismic work represented 83% of total market, driven by NOCs and IOCs primarily targeting oil Total working crew count in U.S. increased by 8% in June 2010 from June 2009. U.S. E&P spending in 2010 expected to increase 11%; international E&P spending expected to increase 10%, mostly due to higher exploration capital spending from NOCs(1) Geokinetics currently has working crews in U.S., Canada, Africa, Latin America and Far East. 1.
