The majority of previous studies of induction logging in fractured formations have typically
focused on the variation in spatial resistivity distribution around the wellbore. However, the …

For designing or calibrating a triaxial induction well-logging tool, efficient simulations of
moving the tool in an arbitrary borehole in an invaded layered medium are essential. The …

Electromagnetic simulation of fractures has a growing importance in geophysical
exploration, where the formation is usually inhomogeneous and modeled as a layered …

This letter presents a fast and memory-efficient 3-D electromagnetic solver for logging-while-
drilling (LWD) tools based on the flipped total field/scattered field-based discontinuous …

This paper presents a study on pseudo-analytic techniques for modeling electromagnetic
sensors used in geophysical well logging. Logging-while-drilling (LWD) tools are sensors …

A nonconformal and nonoverlapping domain decomposition method (DDM) based on hybrid
volume and surface integral equation (VSIE) is presented for modeling complex thin …

Borehole and fracture in well-logging applications are usually simulated by the finite-
element method (FEM) or volume integral equation (VIE). In this work, we propose the …
