Controlled source electromagnetic (EM) methods represent a unique set of geophysical experiments which can be used to determine the properties and state of the deep continental crust. Unlike natural source EM methods, an artificial EM source technique can be designed to optimize resolution and minimize...

Electromagnetic methods that utilize controlled sources have been applied for natural resource exploration for more than a century. Nevertheless, concomitant with the recent adoption of marine controlled-source electromagnetics (CSEM) by the hydrocarbon industry, the overall usefulness of CSEM methods on la...
Controlled-source electromagnetics (CSEM) is an active geophysical technique sensitive to the electrical resistivity of the subsoil, with the peculiarity that the source producing the electromagnetic signal is a man-made device. It has been largely applied for offshore environments in hydrocarbon explora...
Controlled-source electromagnetic surveying was conducted to identify underground faults and potential water hazards that could affect the construction of the Jiutianshan High-speed Railway Tunnel in the Qinling Mountains, western China. The transmitter length was 978 m, and the receivers were positioned...

Three dimensional inversion of Marine Controlled Source Electromagnetic data (MCSEM) data is complex. Achieving an acceptable outcome in a reasonable time frame requires considerable manual input to the problem. We proposed a methodology for preconditioning the inversion for integral equation approximated ...
