Automation of oil and gas exploration by active seismic electric method

Abstract

The paper considers the issues of automation and improving the performance of the field work by the seismic electric method. It is shown that the measurement scheme used today is not optimal. It leads to a long-term deployment of the measuring installation, as well as the inability to use it in difficult geological and climatic conditions. The authors of the paper propose to use special magnetic antennas for recording the electromagnetic field, which eliminate all the drawbacks of grounded electric dipoles. It is shown that if simultaneously registering the various components of the electromagnetic field, it is possible to estimate the depth of the productive layers. The data of observations of seismic electrical effects in the gas-condensate field for various x, y, z components are given.
