Logging While Drilling

LWD and MWD (measurment while Drilling) systems provide wellbore directional sureys,petrophysical well logs, and drilling information in real time while drilling. MWD refers to measurments aquired downhole while drilling that specifically describe directional surveying and drilling related measurments. LWD refers to petrophysical measurments, similar to openhole wireline logs,aquired while drilling. These systems are based on mud telemetry where variations in pressure exercised by the tool can be sensed on the surface via a computer, and thus communication is established.
