METHOD FOR GAS DEPOSIT MONITORING Russian patent published in 2007 - IPC G01V7/00 

FIELD: geophysical industry, particularly use of gravitational prospecting methods for gas deposit development control.

SUBSTANCE: method involves performing periodical observation of gravity change in gravimetric points by arranging two point types, namely basic and regime ones, within the limits of gas deposit, wherein basic gravimetric points are arranged within production well cluster and adapted to determine extracted gas volume, reservoir pressure drop and gas-water surface movement from data obtained during development survey, and regime gravimetric points are located in deposit areas not drained by production wells; determining dependence between gravity change and above development parameters from periodical observations in basic points; using the obtained dependences to determine current gas reserves in deposit, gas distribution and fluid mass movement over total deposit area from determined gravity in regime points.

EFFECT: increased reliability and efficiency of gravitational gas deposit development control in time and volume.
