Subbasalt imaging has gained significant interest in the last two decades, driven by the urge
to better understand the geologic structures beneath volcanic layers, which can be up to …

We have developed an approximation to the Hessian for inversion of 3D controlled source
electromagnetic data. Our approach can considerably reduce the numerical complexity in …

In this study we demonstrate how incorporating controlled source electromagnetic (CSEM)
and magnetotelluric (MT) data in the velocity model building improves seismic depth …

The most utilized technique for exploring the Earth's subsurface for petroleum is reflection
seismology. However, a sole focus on reflection seismology often misses opportunities to …

Marine controlled-source electromagnetic (CSEM) method is a non-invasive offshore
technique used, in association with magnetotelluric and seismic data, for the study of the …

In this paper we explore the West Africa South America analogue proven by the Jubilee and
Zaedyus discoveries in Ghana and French Guiana, respectively. Instead of the Turonian …

For the first time in 3D controlled source electromagnetic data inversion, we explore the use
of the Newton and the Halley optimization methods, which may show their potential when …

New technologies can aid explorationists in the quest to find hydrocarbons in frontier areas.
The Kutch-Saurashtra basin offshore the west coast of India has not been explored …

Seismic sub-basalt imaging is challenging and often leaves remaining uncertainties about
the sub-basalt structures. This paper considers how the marine controlled source …
