METHOD FOR SEISMIC MONITORING WHEN DEVELOPING HYDROCARBON DEPOSITS AT WATER AREAS Russian patent published in 2015 - IPC G01V1/38 

FIELD: physics.

SUBSTANCE: method comprises performing three-dimensional seismic survey and using data thereof to construct a model of the reservoir; predicting the orientation of systems of subvertical cracks and placing producer and injection wells; placing fixed seismic cables at the bottom of the water area over the deposit; detecting seismic traces with elastic vibrations from artificial sources and controlling the process of developing the hydrocarbon deposit based on dynamic and kinematic changes in the detected vibrations when processing the seismic trace. The seismic cables are placed at the bottom of the water area before drilling producer wells. When drilling producer wells, microseismic vibrations excited by the drill bit at the well bottom are detected, during processing of which, based on dynamic and kinematic characteristics, anisotropic properties of the medium in the drilling area are determined, the orientation of the systems of subvertical cracks is refined and the three-dimensional models of the reservoir, the arrangement and drilling path of producer wells, perforation areas and hydraulic fracturing are corrected.

EFFECT: high accuracy of monitoring data.
