Well logging is the practice of recording and analyzing various kinds of data about the rock formations around a borehole during or after drilling. Also called borehole logging, this activity aims to ...

Although commercial applications of composite coiled-tubing systems for drilling and well construction are limited, the work performed in test wells has yielded interesting results. Although ...

A proposed technique determines the hydrocarbon recovery factor and mobility from resistivity logs. This technique provides the petrophysicist with the following benefits: In the early stage of a well ...

Five boreholes were selected in the Gujiao block, Xishan, Taiyuan, China, as calibration wells to identify the coal structure. The geophysical-log responses of the coal structure in the No. 8 coal ...
