Proceedings of SPE/IADC Drilling Conference, 1994
ABSTRACT At the 1991 SPE Forum on MWD, participants expressed the need for more reliable tools, higher data rates and lower cost operations. This paper describes the efforts of one service company to meet those needs. A new tool was specified to meet a goal of 1000 hours Mean Time Between Failure (MTBF).

New MWD Applications Using a Slimline Fully Retrievable MWD Tool
Proceedings of SPE/IADC Drilling Conference, 1987Abstract A new, slimline, fully-retrievable, Directional MWD tool (DMWD®), is finding new applications for and benefits from MWD. Case histories illustrate how compact size and full retrievability are extending MWD into areas of high stuck-pipe risk, small holes, high-temperature drilling, low-budget wells, and remote locations.

MWD FIELD USE AND RESULTS IN THE GULF OF MEXICO
Proceedings of SPE Annual Technical Conference and Exhibition, 1982ABSTRACT Measurement-While-Drilling (MWD) is an important new technology for transmitting data from the bottom of a borehole to the surface without a wireline. The biggest application now is for directional drilling where MWD virtually eliminates downtime for directional surveys.

Accuracy Prediction for Directional MWD
Proceedings of SPE Annual Technical Conference and Exhibition, 1999Abstract This paper describes a new method for predicting wellbore position uncertainty which responds to the current needs of the Industry. An error model applicable to a basic directional MWD service is presented and used for illustration. As far as possible within the limitations of space, the paper is a self-contained reference work,

Measurement of BHA Vibration Using MWD
Proceedings of SPE/IADC Drilling Conference, 1988Abstract Excessive drill string vibration can lead to partial or catastrophic failure of bottom hole assembly (BHA) components. This paper presents data from a microprocessor based downhole vibration data acquisition and recording system, located within a host MWD (Measurement While Drilling) collar in the BHA.

Summary Measurement-while-drilling (MWD) systems, using mud pulse telemetry, are now available to the industry. The most popular sensor package is for directional drilling measurements. Accuracy of such measurements has been proved under field conditions and has resulted in considerable savings in rig time.
