Report on MWD experimental downhole sensors
Measurement while drilling (MWD) provides a means for monitoring drilling and formation parameters as drilling progresses. The technique, based on the use of advanced downhole sensor and telemetry technology, makes possible the real-time acquisition of data that was previously impossible without stopping the drilling operation. Some downhole data, such as weight and torque on bit (WOB and TOB) can be obtained only while drilling. In Summer 1976, Teleco Oilfield Services began an experimental program to demonstrate the feasibility and usefulness of a multisensor MWD tool for real-time measurement of drilling mechanics, formation evaluation, and well-control parameters. A package incorporating six sensors was designed and implemented in a downhole tool capable of transmitting data to the surface by means of mwd-pulse telemetry. In this paper the authors discuss the experimental 6-sensor tool and representative results obtained in a series of 12 field tests in various parts of the world, both onshore and offshore.
