CGX hunt for oil reveals plausible leads

CGX announced last Thurs-day that the geomicrobial survey on its Berbice Block identified more than 20 anomalous leads, one of which is approximately 40 square kilometres.
'We are currently preparing to shoot a 200 km 2-D seismic program to identify the depth and thickness of the source of the micro seepage of hydrocarbons that are associated with several of the larger anomalies," a statement from the company said.
In October, 8,000 soil samples were taken in the Berbice onshore block by CGX and every other sample was analysed for microbes that flourish in the presence of hydrocarbon seepage.
The statement said 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) are indicated as associated with many of the microbial anomalies by the sorbed gas analysis, the statement also said.
CGX said the highly acidic nature of the soil in the area limited the effectiveness of gas analysis from the current shallow soil samples but one set of deeper samples indicates better concentration of hydrocarbons.
CGX plans a limited number of deeper sampling sites to be done simultaneously with the planned seismic.
"We are now in the process of finalising our integration of the geochemical study with our reprocessed aero magnetic data", Warren Workman, Vice President of Exploration is quoted as saying.
"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 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, owned 85.5% by CGX. Additional financing is to be acquired by CGX to proceed with the 2-D seismic programme.
CGX Energy Inc is a Canada-based oil and gas exploration company.
