Abstract

A material improvement of oil recovery can be achieved through application of new approaches to survey the state of geological formations, features of oil fields and operation of producing wells. To monitor the state of fields, reservoir rocks and wells it is reasonable to apply innovative seismic technologies featuring high promptness of survey and providing new information allowing substantially extend the range of geological and production solutions. Presented are examples illustrating the efficiency of integration of innovative SVSL and SLEC seismic technologies and new types of geological models resulting in improved oil recovery. By way of example three models describing urgent geological effects are considered in detail: 1) geodynamics of lunisolar solid-sate tides controlling compaction and decompaction of geological formations and changes in its fracturing; 2) subvertical intensively fractured zones which have deep-seated roots and are forming basic vertical and horizontal fluid streams in reservoirs, particularly, in pay zones; 3) correlation between the steady-state characteristics of microseismic emission of rocks and fluid saturation type (analog of ANCHAR effect). These models are applied to interpretation of observed fields of microseismic emissions and scattered seismic waves to study the situation on the oil field under production and to monitor the efficiency of IOR operations
