Equatorial Margin Source Rock Study

Geochemical Solutions International, Inc. (GSI)

Geochemical Solutions International Inc. (GSI) has completed a geochemical characterization of potential source rock samples from the Foz do Amazonas, Pará Maranhão, Ceará, and Marajo basins of equatorial Brazil. Samples included in this study represent rift, transition, drift and passive margin sections. This study is designed to evaluate the organic richness, hydrocarbon-generating potential, oil proneness, and thermal maturity level of all potential source rock intervals in each of the four basins in order to assist exploration efforts in the less developed regions. This was accomplished by the detailed geochemical analysis of approximately one hundred and fifty (150) well cuttings and/or core samples. These samples were selected based on total organic carbon (TOC) data from more than 8,500 samples representing more than 180,000 m of section from more than 80 wells.

• Total Organic Carbon (TOC)
  
  
• Rock-Eval Pyrolysis
  
  
• Kerogen Maceral Analysis
  
  
• Vitrinite Reflectance
  
  
• Thermal Alteration Index (TAI), Bitumen Extraction
  
  
• Liquid Chromatography
  
  
• Saturate Hydrocarbon Gas Chromatography
  
  
• (Sat GC), Stable Carbon Isotopes
  
  
• Quantitative Biomarker Analysis (GC/MS).
  

Source rock analyses were performed at Baseline Resolution, Inc. labs in Houston.

Results of the study are presented in both analytical and interpretive formats to insure that all findings are accessible to explorationists and research personnel. All geochemical data is provided in hard copy and electronic format. A synthesis and interpretation of all information is presented in a comprehensive final report describing hydrocarbon source potential, oil proneness and thermal maturity. All geochemical data is also provided in digital format in a database contained on CD, which includes a proprietary data browser to facilitate access.
