Measurement-While-Drilling (MWD) is a type of Logging-While-Drilling (LWD) tools that incorporates the measurement tools into the drill-string and provides real-time information to help with steering the drilling bit.Real-time drilling information, MWD uses magnetometers and accelerometers to determine borehole inclination and azimuth during the actual drilling.

 The data is then transmitted to the surface encoded in hydraulic pulses through the mud column (mud pulse telemetry) & decoded at the surface; the data can also be transmitted to an offsite location immediately.

 The course will discuss MWD operations and measurements techniques, MWD/LWD tool assembly and how the tool delivers the information from downhole to surface in addition to all deliverables that could be obtained from MWD/LWD tool.

 Will discuss LWD technologies starting from basic measurements i.e Gamma-ray passing by resistivity, density, porosity to advanced measurements such as acoustic, magnetic resonance and seismic while drilling.
