Marine Controlled-Source Electromagnetic Method (CSEM) is a detection technology profoundly used for marine seismic assistant and reservoir estimation, especially for hydrocarbon exploration. However, the recor
Controlled Source Electromagnetics (CSEM) is a marine geophysical method mapping the subsurface resistivity. A horizontal electric dipole source (HED) is towed across a grid or line of seabed receivers while emitting an electromagnetic field, with a predefined frequency content. The EM signal propagate...
Interpretation of marine controlled source electromagnetic data is potentially influenced by bathymetry. Electromagnetic field strength and direction can be affected by small changes in water column depth. The propagation of electromagnetic fields in complex 3D geo-clcctrical setting cannot be understood by...
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...
Marine controlled-source electromagnetic method (MCSEM), utilizing a horizontal electric dipole source towed close to the seafloor and transmitting an electromagnetic field, is sensitive to horizontal resistors embedded in conductive seabed (Constable and Srnka, 2007). The gas hydrates are orders of mag...
The controlled-source electromagnetic (CSEM) methods can be used to provide a resistivity map of the subsurface structure in geophysical exploration (Mulder et al., 2007). This method has been widely adopted in the application of mineral exploration, environmental study, ground water exploration and...
Method for separating responses of multiple transmitters m a controlled source electromagnetic survey by using mutually orthogonal transmitter waveforms and transforming the combined response to the frequency domain ( 144 ) The mutual orthogonality can be based disjoint frequency spectra or on phase ...
The method for correcting the phase of measured electric signals or magnetic signals of field data from a controlled source electromagnetic survey (CSES) by comparing the measured field data corresponding to a selected frequency to the simulated data for various signal source receiver offsets () and...
