METHOD OF ESTIMATION OF PAYLOAD CAPACITY OF NATURAL CRYOGENIC RESERVOIRS Russian patent published in 2015 - IPC G01V9/00 B65G5/00 

FIELD: mining.

SUBSTANCE: definite volume of drainage brines is injected through wells drilled to permafrost depth limited by low permeability deposits. Area of brines flow (S) is measured and at the plotted sections the thickness of watercut stratum is determined in centre of the repressive dome fold to identify the definite (n^th) time moment (h_n). Effective capacity coefficient of the reservoir (n_eff) is determined. Then total thickness of the watercut permafrost (V_total) is estimated considering the ecological safety for the final stage of injection of the drainage brines within the area.

EFFECT: increased authenticity of estimation of payload capacity of the reservoir upon achievement of the ecological safety during brines injection to permafrost.
