Abstract—A complex study of the structure and rock composition of an exploited oil and gas field on the Yamal Peninsula (Russia) has been performed. The experimental equipment, based on an original deep ground-penetrating radar (GPR) GROT 12, included also a seismic sensing complex. GPR transects and hodograph images have been obtained. The GPR data are compared with seismic data in the general processing system. This complex study of the electromagnetic and acoustic parameters of a layered deposit to actual depths of more than 500 m has been performed for the first time in the engineering practice. The key advantage of the electromagnetic method over the seismic method (higher sensitivity to changes in the saturated bed content (water, oil, gas, condensate) over depth) is implemented.
Keywords: ground-penetrating radar (GPR), transect, hodograph image, seismogram, radarogram, ultra-wideband pulses, permafrost, common depth point (CDP), common source point (CSP)
