Abstract
MWD is the process by which certain information is measured near the bit and transmitted to surface without interrupting normal drilling operations. The type of information may be:
-
(a)
directional data (inclination, azimuth, toolface);
-
(b)
formation characteristics (gamma-ray, resistivity logs);
-
(c)
drilling parameters (downhole WOB, torque, rpm).
