SURVEYING USING VERTICAL ELECTROMAGNETIC SOURCES THAT ARE TOWED ALONG WITH SURVEY RECEIVERS

摘要

A system to perform a marine subterranean survey includes at least one vertical electromagnetic (EM) source and at least one EM receiver to measure a response of a subterranean structure that is responsive to EM signals produced by the vertical EM source. At least one tow cable is used to tow the EM source and EM receiver through a body of water.
