For hydrocarbon applications, seismic exploration is the workhorse of the industry. Only in
the borehole, electromagnetic (EM) methods play a dominant role, as they are mostly used …

A practical limitation in the use of generalized 3D forward modeling algorithms for inversion
of electromagnetic data is the high computational cost of solving large, ill-conditioned …

The effect of compaction upon shale electrical anisotropy is analyzed using multi-component
induction logging data acquired in Miocene shales. Multi-component induction logging …

Adaptations of existing triaxial cells for ultrasonic P‐and S‐wave measurements are well
documented. This paper proposes further modification of such a cell so that also resistivity …

Field and numerically simulated data show that coplanar induction measurements (σ xx and
σ yy) are affected by both conductive and resistive muds. The effect is, for a resistivity …

A series of tests were carried out employing a modified triaxial cell able to measure both
elastic and electric properties simultaneously at reservoir conditions. Measured quantities …

The capability of a multicomponent induction measurement to detect fractures around
boreholes is studied using both numerical simulation and field data analysis. With examples …

The presented work is devoted to development of new electromagnetic methods of
geophysical logging in oil and gas wells. The aim of the work is the development of an …
