PROVIDING COMMUNICATIONS REDUNDANCY USING ONE OR MORE LOOP CONNECTIONS IN A SUBTERRANEAN SURVEY SYSTEM

摘要

A subterranean survey system includes a sensor string having a communications link and a plurality of survey sensors connected to the communications link. The sensor string has a loop connection to provide communications redundancy, and the survey sensors are used to detect signals affected by a subterranean structure. A first router is connected to the sensor string, and a transport network is connected to the first router. The first router communicates data from the survey sensors over the transport network.
