Dipmeters are micro-resistivity logs that detect the orientations of bed boundaries and borehole elongations. Borehole-imaging logs provide video, density, gamma-ray, acoustic and/or electrical images ...

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 ...

LWD acquires formation evaluation and wellbore data in real time while the bit is cutting rock. Sensors housed in drill collars measure gamma ray, resistivity, density, neutron porosity, sonic, NMR, ...
