Abstract

Summary

The work is devoted to fundamental research aimed at the theoretical justification of an electromagnetic method for extracting electrophysical and structural information on the Bazhenov Formation as a unique oil-bearing stratum. The current lack of a common approach to its development, as well as the poor efficiency of the existing techniques for interpreting conventional geophysical methods data, necessitates the creation of new breakthrough technologies. We propose a method of pulsed sounding, which has a considerable depth of investigation and can be used in both well logging and crosshole measurements for identifying lateral heterogeneities and spatial localization of oil-promising zones in the interwell region. To study the electrophysical properties of the rocks exposed by subvertical, deviated and subhorizontal wells, highly efficient algorithmic and software tools were developed. They enable simulating pulsed sounding data and estimating the resolution of an observation system. We performed the numerical simulation and sensitivity analysis of the signals in typical models of the Bazhenov Formation, and showed that the new sounding method provides the capability of lateral tracking the top and bottom of the Bazhenov Formation, as well as studying the transition zone in the overlying and underlying deposits.
