During October 2003, 8,000 soil samples were taken in the Berbice onshore block in Guyana. At the GeoMicrobial Technologies (GMT) labora-tory in Oklahoma, every other sample was analyzed for microbes that flourish in the presence of hydrocarbon microseepage. Infill analysis of over 1,000 samples in areas of high readings has significantly improved the definition of the leads. Thermogenic hydrocarbons (not Biogenic/Swamp gas) is indicated as associated with many of the microbial anomalies by the sorbed gas analysis.
The highly acidic nature of the soil in the area has limited the effectiveness of sorbed gas analysis from the current shallow soil samples, however one set of deeper samples indicates better concentration of hydrocarbons (less affected by the acidic soil) so CGX plans a limited number of deeper sampling sites will be done in conjunction with the planned seismic.
"We are now in the process of finalizing our integration of the geochemical study with our reprocessed aeromagnetic data", stated Warren Workman, Vice President of Exploration for CGX. "Using the aeromag data, we have identified basement highs and fault structures that may be effective in forming traps to migrating hydrocarbons. We have reviewed the geology associated with the Suriname oil production on trend. The seismic will provide definition as to potential trap on several of our larger Microbial anomalies and tie to our aeromag features."
The 800,000-acre Berbice block is held by ON Energy Inc., a Guyanese registered company, currently owned 85.5% by CGX. Additional financing will be required within ON Energy to proceed with the 2-D seismic program. CGX will support that financing as it evolves.
