West Africa: Proven experience & results that reduce exploration risk & uncertainty
RSI has conducted numerous projects focused on West African reservoirs in the Upper Cretaceous (e.g. Santonian, Cenomanian) and Lower Cretaceous (e.g. Albian, Aptian). Experience gained during these projects combined with state-of-the art proprietary technologies enable our team to deliver reliable estimates of reservoir properties and potential drilling targets to our clients.

| What our Clients have said about our work: | |||
|---|---|---|---|
|
“We are looking forward to working with the team at Rock Solid Images on this important seismic inversion study. RSI’s knowledge of the rock physics and reservoir properties of these play types in the region, combined with an impressive track record in West Africa was the primary reason for awarding this work. Our expectation is that this study will significantly de-risk our drilling decisions and, ultimately the appraisal of this block.” |
“This work unequivocally demonstrated the impact that rigorous rock physics analysis can make on risk reduction in rank exploration areas such as those that characterize our deepwater West African and Ukrainian exploration portfolios." |

|
“We are pleased that the recently completed Mahogany-3 well has validated the geological and geophysical models we have worked on with the team at Rock Solid Images. The well was drilled in a location identified by OHM Rock Solid Images initial seismic inversion and we particularly look forward to the reservoir property inversion results at the Mahogany Deep formation level which appears at this point to be a separately trapped reservoir and which we will be further appraising in late 2009.” |
“We have collaborated with the Rock Solid Images team on numerous of our exploration initiatives in West Africa, including Ghana’s Jubilee Field. We have been impressed with their commitment to technical excellence and customer satisfaction and are pleased to select them for this important role.” Kenny Goh, Kosmos Energy Senior Vice President and partner, and Robin Sutherland, Tullow Exploration Manager |

Rock Physics
- West Africa regional library of modeled shear Wave velocity logs
- Regional knowledge applied to every well by recognized experts in the field
- Comprehensive software package for modeling and analysis, iMOSS®, to determine the seismic signatures of reservoir properties
Seismic & Well Data Conditioning
- Geophysical Well Log Analysis (GWLA®) for quantitative interpretation purposes
- AVATAR® seismic data conditioning to remove or suppress undesirable effects for improved inversion and interpretation results
Pre & Post-Stack Seismic Inversion
- A well-established strategy for predicting reservoir properties such as lithology, porosity and fluids by inverting seismic data for P and S Impedances and their derivatives
- Extended Elastic Impedance (EEI)
Geological Interpretation
- Results put into context with regional expertise
- Advanced Seismic Attribute Calibration and Seismic Facies Analysis
- Combination of impedance, AVO, Hilbert Transform, Spectral Enhancement and other attributes classified using a proprietary neural network technology (LITHANN®)
Electromagnetic (EM/MT), Inversion & Integration with Seismic & Wells (WISE™)
- By integrating complementary and independent sources of information and exploiting the strengths of each, estimates of rock and fluid properties such as hydrocarbon saturation, lithology and porosity can be obtained with greater confidence than from any single data type
- WISE capitalizes on the independent assessment of reservoir prospectivity by integrating the elastic (seismic) and electric (resistivity) properties of the subsurface
