GCHD technology is mainly used to predict the geochemical properties of the reservoir in depth (oil, condensate or gas etc.). It applies the proprietary acid extraction technique with gas chromatographic analysis to detect the concentration of sorbed soil gas (C1-C5) in surface soil or sediments. The origin and composition of the migrated (or reservoired) hydrocarbons can be inferred from the hydrocarbon ratios and isotopic analysis.

Petroleum exploration surface geochemical surveys can be used to map the light hydrocarbons expressed through microseeps from active petroleum and natural gas reservoirs at depth.
The integration of multi - disciplinary information in Geology, Geophysics, Geochemistry and Geo - microbiology can significantly improve the accuracy and reliability of prospect identification
GMHD is a new generation of hydrocarbon detection technology. It is widely applied to predict the occurrence and distribution of oil & gas accumulations at
