Gas and mercury surveying
The gas and mercury studies are used in geological prospecting in combination with geochemical and geophysical methods for mapping ore bodies and, to a lesser extent, as an indirect method for revealing hydrocarbon deposits and mapping petroleum product plumes. The […]
Radiometric methods
Radiometric studies are carried out on near-surface sediments in combination with lithological, gas and geochemical, and hydrological gas and geochemical methods, usually on shallow boreholes, holes, or “pits”. Radiometric methods include gamma surveying and radonometry (on soils and surface water). […]
Geomicrobiological method
The geomicrobiological method (GMB) is used in combination (or independently) with geochemical studies to identify and localize accumulations of hydrocarbon fluids at depth. The method has been widely developed abroad and it is used in various climatic (including in the […]
Geochemical studies in water areas
Marine geochemical exploration In the search and exploration of oil and gas in the seas (shelf), as well as in lakes (reservoirs), the main geochemical method is gas geochemical surveying in the near-bottom waters and bottom sediments in which, as […]
Comprehensive hydro-gas and geochemical surveying for surface water sources
Hydrogasogeochemical survey Geochemical studies in oil and gas prospecting include anticipatory reconnaissance hydro-gas geochemical surveying at a scale of 1: 500,000-200,000. The hydro-gas and geochemical surveying of surface water ingresses are carried out in summer, less often in winter. The […]
Geochemical studies of deep borehole sections
Downhole Geochemistry The borehole geochemistry methods are conducted for a more rapid and in-depth study of borehole sections, forecasting, and evaluation of oil and gas saturation of potentially productive horizons, as well as studies of formation fluids. One of the […]
Geochemical methods of ore and precious metal deposit prospecting and exploration
Geochemical methods, in comparison with traditional geological and geophysical studies, enable not only to forecast metallogenetic features of the sedimentary section on the structural-tectonic basis but also to rank the forecast sites on reserves and conduct a qualitative assessment of […]
Physicochemical modeling of oil and gas systems
It is carried out on a thermodynamic basis using PC “Selector-C” for solving a wide range of tasks, including: evaluation of different catagenesis degree types of DOM of potentially oil and gas horizons (OGH); identification of DOM oil-production potential in […]
