Abstract

At present, sounding methods based on the effect of electromagnetic pulses on the environment are widely used for marine exploration of hydrocarbon deposits. The exploration is performed using research systems with special equipment fixed in the water column. The goal of this work is to develop equipment and methods for marine electrical prospecting that would allow reliable predictions of petroleum fields in the underlying environment with reduced labor intensity of the necessary surveys. For this purpose, a subsurface array for marine electrical prospecting during vessel movement is proposed. The effective frequencies, current strengths in cables, and the size and efficiency of the array are determined using both the theoretical knowledge of the operation of similar arrays in similar environments and numerical simulation of the developed array. The 3D finite element method is used for mathematical modeling.
