A meaningful solution to an inversion problem should be composed of the preferred
inversion model and its uncertainty and resolution estimates. The model uncertainty …

Electromagnetic methods that utilize controlled sources have been applied for natural
resource exploration for more than a century. Nevertheless, concomitant with the recent …

Electromagnetic (EM) imaging aims to produce large-scale, high-resolution soil conductivity
maps that provide essential information for Earth subsurface exploration. To rigorously …

Wells and boreholes are routinely steel-cased in oil and gas fields and geological storage
sites. There have been a number of studies on the effects of a steel-cased well on various …

Controlled-source electromagnetic (CSEM) measurements are complementary data for
magnetotelluric (MT) characterization although its methodology on land is not sufficiently …

Reservoir characterization and monitoring represent some of the most ambitious goals for
geophysical methods. Several challenges are involved, including sensitivity to the …

The presence of steel-cased wells and other infrastructure causes a significant change in
the electromagnetic fields that has to be taken into consideration in modeling and …

The borehole-to-surface electromagnetic (EM) method is a viable imaging and monitoring
tool for energy reservoirs, geologic storage, geothermal exploration, fault zones, and other …

We analyze the electromagnetic fields arising in the vicinity of a vertical steel casing due to
the excitation of a vertical electric field antenna placed in the borehole below the casing …

Reservoir simulations and history matching are critical for fine-tuning reservoir production
strategies, improving understanding of the subsurface formation, and forecasting remaining …
