The geological project task was to conduct exploratory geochemical surveys with snow cover (in winter), surface sediments (soils) and surface waters (in summer) to assess the potential of such types of geochemical survey in Nizhnevartovsk district of Khanty-Mansi Autonomous Area.

Complex geochemical anomalies are mainly assigned to the maximum values of seismic waves transit time between B3 and A reflectors (Jurassic sediments), which is the evidence that oil deposits are associated with fringe zones of rocks-collectors of Jurassic sediments.

Geochemical survey

The geochemical survey may be performed in area, as well as, along the seismic lines

.

The geochemical survey along the seismic lines can be

executed simultaneously with seismic exploration works with point spacing of geochemical tests along seismic lines, including sampling while blast-hole drilling by the specialists of the seismic department for placing the explosives.

http://www.geochemistry.ruSlide21

Advantages

:

Such approach to the performing of the works

will significantly increase their informative value, and it will allow not only to study the geological structure, but also to obtain the information related to

oil-and-gas-bearing capacity of subsoil.

The

survey of geochemical samples prior to the seismic exploration works will allow to increase the efficiency of exploration services and determine the local areas for organizing of detailed works and choice of the points of drilling deep wells.Further it will help reducing the costs of exploration

It will considerably

shorten the terms of discovery and development

of the new field of oil and gas.

Apart from the territory of the Western Siberia, geochemical surveys were conducted in areas and license blocks of:

Komi Republic – three license blocks Bashkortostan Republic – one license block Mari El Republic – one license block

Volgograd Region – five license blocks Krasnoyarsk Territory –

two license blocks
