Establishment of domestic technology for marine CSEM survey and future prospects

Abstract

In recent years, Marine controlled source electromagnetic（CSEM）technology has played an effective role to reduce the exploration risk offshore. Meanwhile, the application of Marine CSEM is not always applicable due to its expensive survey cost and difficulty of quality control for data acquisition and analysis. Therefore, the authors constituted the research consortium and advance the Marine CSEM technological development based on the expertise cultivated at university and research institute. In this paper, we discuss the acquisition, processing, inversion, and evaluation of the data obtained during the demonstration survey.
