Definition - What does LWD mean?
LWD, an acronym for Logging While Drilling, is a method of transporting logging tools to a wellbore. It is an innovative technology that provides tailored and reliable solutions to undertake geological challenges. Since the early 1970’s, the technique is subject to drilling as it is capable of logging in any direction and in tough environments. LWD can increase the production of the well and reduce well construction costs as all the rock parameters and properties are logged during drilling process only.
Petropedia explains LWD
The LWD process helps oil producing organizations to take the measurements of the wireline quality formation during drilling. There are various types of Logging While Drilling such as electromagnetic drilling, acoustic logging, nuclear logging and nuclear magnetic resonance logging. The tools used for LWD include large drill collars, sensors, batteries and electronics. As from 1970 lots of improvements have been made to LWD so as to improve the technology. LWD is widely used for evaluating a formation, geo-steering and other drilling purposes. The benefits of LWD include:
- Complete analysis of the rock mechanical properties.
- It improves pore pressure estimates.
- It is more efficient drilling process.
- Real-time adjustments of mud weight.
