СПОСОБ И УСТРОЙСТВО ДЛЯ ОПРЕДЕЛЕНИЯ ПРИРОДЫ ПОДВОДНЫХ РЕЗЕРВУАРОВ

摘要

A system for investigating subterranean strata. An electromagnetic field and a seismic event are applied from the same location and the responses are detected using respective receivers both located at a second location spaced from the first. The responses are combined to identify the presence and/or nature of subterranean reservoir. The refracted wave components are used.
