METHOD OF HYDROCARBON POOL PROCEEDING FROM PRINCIPLE OF PASSIVE ADSORPTION Russian patent published in 2013 - IPC G01V9/00 

FIELD: oil-and-gas industry.

SUBSTANCE: hydrocarbon gases are sorbed by means of nonexpendable sorbents-collectors in soil bores deep to at least 0.5 m. Note here that said sorbents-collectors at elevation of expected productive beds are located in dense grid with spacing of 250-400 m there between while, outside said elevations in loose grid, of 500-800 m. Samples are analysed to accuracy of 1 picogram to extract at least 150 hydrocarbons. Results of the analysis are compared with reference data. Said data is interpolated in algorithm of training and mapping system with the help of analysis of primary components, discriminate analysis and hierarchical cluster analysis. Adapted criteria are used to simulate deposit.

EFFECT: higher accuracy.
