Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental, scientific and geotechnical studies.

Well logging is an evaluation method in which a logging crew lowers a special tool, a sonde, into the well and then pulls it back up. As the sonde passes the formations on its way up the wellbore, it senses …

Jul 28, 2016 · Well logs present a concise, detailed plot of formation parameters versus depth. From these plots, interpreters can identify lithologies, differentiate between porous and nonporous rock …

Dec 7, 2022 · There are many different types of well logging, including but not limited to, resistivity, sonic, caliper, electric, seismic, and radioactivity. Each type of well logging involves a different …

This continuous record, known as a well log, helps geologists and engineers assess the production potential of a well and address various geological challenges, such as understanding the …

Well logging involves lowering specialized instruments into a borehole to measure the physical properties of the surrounding rocks and fluids. The recorded data is presented as continuous, depth …

This chapter provides a general introduction to well logging principles and methods that will be used throughout the book. Succeeding chapters (2 through 6) introduce the reader to specific log types.

Well logging, field technique used in mineral exploration to analyze the geologic formations penetrated by a drill hole. If the hole has been drilled by using coring techniques, the core provides a visual …

Sep 17, 2025 · Well logging acquires in-situ measurements of rock and fluid properties along the wellbore to quantify reservoir quality, fluids, and well integrity. It underpins petrophysics, …

Feb 26, 2024 · What Is Well Log Analysis in Oil and Gas? Well log analysis in the oil and gas industry involves lowering instruments called logging tools down into the wellbore, which records the …
