Measurement While Drilling (MWD)

1987
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 ...

Retrofitting Drilling Rigs with MWD

International Conference on Measurement While Drilling Proceedings
"Measurement While Drilling (MWD) kits are generally designed for specific types of rigs. However, for most drilling companies it is important to be able to retrofit their existing fleet with a single MWD kit, to be able to generate insights on the data acquired by MWD on different types of rigs.

A Model for Measuring the Effectiveness of MWD Systems

Proceedings of SPE/IADC Drilling Conference, 1987
ABSTRACT A conceptual framework can be developed for measuring effectiveness of MWD services in terms of availability, reliability and capability. Availability is defined as the condition of being ready to provide services when required. Reliability is defined as providing service during the specified interval of a bit run. Capability is

New Ultrasonic Caliper for MWD Operations

SPE/IADC Drilling Conference, 1991
Abstract An ultrasonic tool has been developed for MWD applications that simultaneously performs realtime bore-hole caliper measurements and realtime gas influx detection. The caliper determines the ovalness of the hole with a high degree of accuracy and excellent vertical resolution.
