MWD todayMeasurement-while-drilling (MWD) tools and tech-niques have made steady, if not spectacular, progressduring the year. Mud-pulse telemetry has become amature technology.Teleco Oilfleld Services, Inc., has successfully used itspositive-pulse MWD tool on more than 1,200 wells.About 60% of these runs were made behind mud mo-tors, often in high angle holes. Three parameters aremeasured--azimuth, inclination and toolface heading.Data is presented visually on the drilling floor as hardcopy. The operator, however, must still perform surveycalculations.
