Logging while drilling; Measuring while drilling

Measurements-while-drilling (MWD) and logging-while-drilling (LWD) logs are also taken downhole. They are either transmitted to surface by mud pulses, or else recorded downhole and retrieved later when the instrument is brought to surface. The measurement of formation properties during the excavation of the hole, or shortly thereafter, through the use of tools integrated into the …
