Borehole imaging encompasses a suite of tools and methods that generate high-resolution, oriented images of borehole walls to characterise subsurface geology. Techniques include acoustic and optical ...

Electrical resistivity is a basic property that quantifies a material’s opposition to current flow—it’s the reciprocal of conductivity. The resistivity of a material depends upon several factors, ...

This chapter addresses methods for the remote detection and characterization of fractures in the subsurface. These indirect detection methods are mainly geophysical in nature and rely on the physical ...

With the recent advancements in directional drilling and the use of rotary-steerable systems, more deviated and horizontal wells are being drilled and evaluated around the world, especially in Saudi ...
