Understanding the major controlling factors on the horizontal resistivity-depth trends of sedimentary rocks in any given basin around the world are interesting from both scientific and commercial perspectives. Hence, we propose a workflow that combin

We present a structural smoothing regularization scheme in the context of inversion of marine controlled-source electromagnetic data. The regularizing hypothesis is that the electrical parameters have a structure similar to that of the elastic parame

This paper presents the theory to eliminate from the recorded multi-component source, multi-component receiver marine electromagnetic measurements the effect of the physical source radiation pattern and the scattering response of the water-layer. The

Marine controlled-source electromagnetic (CSEM) surveying, also called seabed logging, is a technique for finding resistive layers in the subsurface, which can be hydrocarbon-saturated reservoirs. The EM signal from the horizontal electric dipole sou

Cross-property relations are useful when some rock properties can be measured more easily than other properties. Relations between electrical conductivity and seismic velocity, stiffness moduli, and density can be obtained by expressing the porosity

CSEM inversion for large 3D models is computationally very intensive, making the use of advanced inversion algorithms like Gauss-Newton particularly challenging. To overcome this problem model compression techniques can be applied. By decreasing the
