Logging While Drilling (LWD)

Definition - What does Logging While Drilling (LWD) mean?

Logging While Drilling (LWD) is a method of transporting logging tools to the wellbore as a part of bottom hole assembly. It is an innovative technology that provides tailored and reliable solutions to undertake geological challenges. Since early 1970’s, the technique is subject to drilling as it is capable of logging in any direction and in a tough environment. Specific tools used for LWD include large drill collars, sensors, batteries and electronics. LWD can increase the production of the well and reduce well construction costs.

Petropedia explains Logging While Drilling (LWD)

The process of taking measurements of the wireline quality formation during drilling is called Logging While Drilling. There are various types of Logging While Drilling such as electromagnetic drilling, acoustic logging, nuclear logging and nuclear magnetic resonance logging. As from 1970 to 2010 lots of improvements were made so as to improvise 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.
  • More efficient drilling process.
  • Real-time adjustments of mud weight.
