  • Method of conducting a seismic survey
    Patent number: 9030909
    Abstract: A method of conducting a seismic survey of an area including a region of high seismic velocity regimes in a shallow overburden. According to the method, a zone is identified in which the boundary of the high seismic velocity region has a substantially constant critical angle and a course is plotted through the identified zone. A zone based directional seismic source is applied sequentially, with a directivity angle equal to or close to the measured critical angle. The response is detected using receivers.
    Type: Grant
