As the industry leader in logging-while-drilling (LWD) technology, SLB creates advanced LWD services that acquire high-quality data for accurate geosteering and more-informed formation evaluation, so you can work proactively as you drill.

EcoScope multifunction logging-while-drilling service integrates a full suite of formation evaluation, well placement, and drilling optimization measurements into a single collar that can be deployed faster than conventional LWD tools.

Abbreviation for logging while drilling. The measurement of formation properties during the excavation of the hole, or shortly thereafter, through the use of tools integrated into the bottomhole assembly. LWD, while sometimes risky and expensive, has the advantage of measuring properties of a formation before drilling fluids invade deeply.

LWD, while sometimes risky and expensive, has the advantage of measuring properties of a formation before drilling fluids invade deeply. Further, many wellbores prove to be difficult or even impossible to measure with conventional wireline tools, especially highly deviated wells.

Measurements-while-drilling (MWD) logging tools, in some cases known as logging while drilling (LWD) tools, are drill collars into which the necessary sensors and electronics have been built. Wireline logging tools are typically cylinders from 1.5 to 5 in. [3.8 to 12.7 cm] in diameter.

Logging while drilling (LWD) has emerged as a cornerstone technology, providing real-time data about subsurface formations as drilling progresses. However, traditional LWD methods, while effective, rely on deploying sophisticated and expensive tools downhole.

Aug 15, 2014 · Two new logging-while-drilling (LWD) services have been announced to improve measurements in those areas respectively. The GeoSphere reservoir mapping-while-drilling service enables engineers to image a huge reservoir volume, coaxial with the wellbore, and more than 200 ft (61 m) in diameter.

This document discusses logging while drilling (LWD) tools from Schlumberger including caliper, ultrasonic, and telemetry tools for collecting downhole data while drilling.
