Tests provide further development toward an EM streamer: Towed streamers collect EM and seismic data simultaneously

摘要

During 2009, Petroleum Geo-Services (PGS) successfully tested a novel method of conducting marine controlled-source electromagnetic (CSEM) surveys. The new approach to electromagnetic (EM) surveying has the objectives of aligning EM survey operations with those of seismic operations, improving EM data sampling, and broadening the application of EM technology for geophysical surveying. Building on the information gained from tests in 2009, a new suite of data was acquired during the summer of 2010 to further the development.
