Abstract

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. LWD offers similar functionality as wireline logging with differences in data quality, resolution, and/or coverage. LWD tools are basically large, instrumented drill collars. In general, the practice is to put the “most important” tools closest to the bit. LWD tools can go anywhere that the bit can go, so they tend to be significantly more effective in extended-reach-lateral horizontal wells. They send their data to the surface using either pulses into the mud or signals superimposed on the drill pipe. Because the environment on the rig floor is so noisy, two-way communication is not possible and communication from the tool to the surface is very slow (1–2 bits of information/second) .
