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

Steel-cased wells used as long electrodes (LEs) in a surface-electric or electromagnetic
survey can enhance anomalous signals from deep hydraulic fracturing zones filled by …

Wellbore integrity is of paramount importance to subsurface resource extraction, energy
storage, and hazardous waste disposal. We have developed a simple noninvasive …

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 …

Electrically conductive fluid injected during the operation of hydraulic fracturing can be
mapped by anomalous electromagnetic (EM) fields under the excitation of controlled EM …

Large-scale CO2 and energy storage is a mandatory part of the green shift to reduce CO2
emissions and limit consequences of climate change. Large-scale storage will require the …

The numerical mode matching (NMM) method is a widely used semianalytical approach for
modeling the propagation of electromagnetic (EM) waves in orthogonal-plano-cylindrically …

Electromagnetic (EM) exploration is one of the most important geophysical methods for
monitoring hydraulic fracturing. However, recently published research has focused on the …

We investigate the effects of coupled multiphase flow and geomechanics in the hydraulically
fractured reservoirs numerically. We account for poromechanics of flow within a discrete …

Electrical signals in the vicinity of excited steel-cased borehole sources offer significant
potential for monitoring fracture zones filled with highly conductive proppant. However …
