MWD/LWD refer to measurement and logging while drilling. The MWD operator measures the path of the wellbore while it is being drilled, and this data is then used to help plan the direction that the well will be drilled. LWD, while sometimes used interchangeably with MWD, refers more to the process of obtaining information about the rock being drilled, while MWD is more about the drilling operation.
