1 Advanced Data Processing Presented at the Lehman Brothers Investor Day By Nick Bernitsas (Senior VP, GXT Imaging Solutions) December 6, 2007 Houston, Texas USA

2 Today s Discussion An Overview of Data Processing at ION DP in Support of BasinSPANs DP as a Structural Imaging Tool DP for Reservoir (XinChang) [ 2 ]

3 ION s Global Footprint in Data Processing January 2004 Geophysical Service Centers (GSCs) [ 3 ]

4 ION s Global Footprint in Data Processing Today Geophysical Service Centers (GSCs) [ 4 ]

5 Our Global Scale in Data Processing 20+% market share where we have established Geophysical Service Centers Revenues growth of 20+% for several years in a row ~250 total employees at YE07 Large, centralized compute infrastructure projects per year (several over 3,000 sqkm) Broad experience base With (super)majors, independents, NOCs Most offshore basins; many onshore basins GSC Project Experience [ 5 ]

6 Today s Discussion An Overview of Data Processing at ION DP in Support of BasinSPANs DP as a Structural Imaging Tool DP for Reservoir (XinChang) [ 6 ]

7 Seismic from an Oil Company Perspective GXT Prepared to Address the Fundamental Questions Entrapment Gas Cap Oil W ater Seal Rock Reservoir Rock Migration 120 F Generation 350 F The Fundamental E&P Questions How is the petroleum system put together? Do I have a trap? Do I have a reservoir? What fills the reservoir? Addressed via GXT Offerings BasinSPANs Structural imaging - RTM Lithology imaging - Full-wave Fluid detection Full-wave [ 7 ]

8 GXT Data Processing for BasinSPANs Supporting Petroleum System Understanding Since 2001 BasinSPAN programs Multi-client imaging programs Deliver basin-scale understanding of petroleum systems, from the source up Basin evolution and architecture Source rock distribution and migration pathways Potential new play types Not a typical spec product Designed by regional experts with input from underwriters Involves host governments and NOCs at an early stage Incorporates state-of-the-art data processing (PreSDM standard) Includes integrated interpretation Benefits to our customers Holistic, basin-level understanding Mitigates risk of exploration programs Delivers new insights into basin architecture and evolution Benefits for ION Provides valuable experience in new basins that we apply in our proprietary processing projects Fortifies our technical standing with the NOCs and the IOCs involved Enhances expertise to create the technical value propositions for new business lines [ 8 ]

9 Unlocking a Petroleum System CongoSPAN vs. Legacy Libraries (Offshore Angola) km Legacy Products Km 10.0 < CongoSPAN 0 Km 0 Km 10 Km 10 Km 20 Km 20 Km [ 9 ]

16 Seismic from an Oil Company Perspective As One Gets Closer to the Reservoir, P-wave Has Lesser Utility Questions Geology Seismic P-wave Do I have a trap? Structure Where? Very good Do I have a reservoir? Lithology What fills the reservoir? Fluids What? Average Average Entrapment Gas Cap Oil Water Seal Rock Reservoir Rock Migration 120 F Generation 350 F 2480 [ 16 ]

17 Seismic from an Oil Company Perspective Full-wave Provides Additional Reservoir Insight Questions Geology Seismic P-Wave Full-wave Do I have a trap? Structure Where? Very good Excellent Do I have a reservoir? Lithology What fills the reservoir? Fluids What? Average Very good Average Very good Entrapment Gas Cap Oil Water Seal Rock Reservoir Rock Migration 120 F Generation 350 F 2480 [ 17 ]

18 Differences in Acoustic Wave Propagation Full-wave Involves Measuring Both P-waves and S-waves Fluid or Solid Solid Only [ 18 ]

24 Regional Tectonics Impacted XinChang Stress Fields Around Tibetan Plateau Zhang et al. Geology (2004) [ 24 ]

25 Regional Stress Fractures Limited Connectivity Perpendicular to Stress Direction Connectivity mostly in two dimensions Limited fracture network and drainage area per well Connectivity Fast depletion Connectivity Stress direction Stress direction Connectivity [ 25 ]

26 Hydraulic Fracturing A Mechanism for Creating 3D Connectivity Connectivity in all three dimensions Extensive fracture network and drainage area per well Connectivity Slower depletion Connectivity Stress direction Stress direction F R A C J O B Connectivity [ 26 ]

27 Optimizing Reservoir Potential Using Full-wave to Determine Lithology and Fracture Patterns Tfast ~ N-S NNW-NNE Similarity Lineaments (p-wave) Nature s frac. job Tfast ~ E-W Analog to the x851 and x856 wells E-W Deep fracture seated direction fractures: (c-wave) natures frac job Txu24 [ 27 ]
