The finite element method has always been a mainstay for solving engineering problems
numerically. The most recent developments in the field clearly indicate that its future lies in …

We present 2.5 D fast and rigorous forward and inversion algorithms for deep
electromagnetic (EM) applications that include crosswell and controlled-source EM …

The rational Krylov space is recognized as a powerful tool within model order reduction
techniques for linear dynamical systems. However, its success has been hindered by the …

Modeling of Resistivity and Acoustic Borehole Logging Measurements Using Finite Element
Methods provides a comprehensive review of different resistivity and sonic logging …

We have developed a frequency-domain joint electromagnetic (EM) and seismic inversion
algorithm for reservoir evaluation and exploration applications. EM and seismic data are …

We consider a problem of computing the electromagnetic field in 3D anisotropic media for
electromagnetic logging. The proposed finite-difference scheme for Maxwell equations has …

We present an algorithm, and a 2D implementation for a fully automatic hp-adaptive strategy
for elliptic problems. Given a mesh, the next, optimally refined mesh, is determined by …

The numerical and computational aspects of the overlap formalism in lattice quantum
chromodynamics are extremely demanding due to a matrix–vector product that involves the …

Accurate determination of reservoir petrophysical parameters is of great importance for
reservoir monitoring and characterization. We developed a joint inversion approach for the …
