MWD & LWD EQUIPMENT’S

Logging while drilling (LWD or Measurement while drilling (MWD), the terms are used interchangeably) is a general term to describe systems and techniques for gathering down-hole data while drilling without the requirement to remove drill pipe from the well.

Providing information on porosity, resistivity, acoustic waveform, hole direction, and weight on bit, LWD transmits logging measurements at regular intervals while drilling is taking place. Data is transmitted to the surface through pulses through the mud column (also known as mud pulse of mud telemetry) in real time

Measurement-While-Drilling (or MWD) is a type of well logging that incorporates the measurement tools into the drill string and provides real-time information to help with steering the drill. Measurement While Drilling.
