MWD and LWD 901 successfully in many air and gas drilling situations. The various manufacturers of these motors can give specific information concerning the performance characteristics of their respective motors operated with air and gas drilling techniques. The critical operating characteristic of these motors, when operated with unstable foam, is that these motors must be loaded with weight on bit when circulation is initiated. If the positive displacement motor is allowed to be started without weight on bit, the rotor will speed up quickly to a very high speed, thus burning out the bearings and severely damaging the elastomer stator. MWD AND LWD Most of the cost in a well is expanded during the drilling phase. Any amount of information gathered during drilling can be used to make decisions regarding the efficiency of the process. But the scope and ultimate cost to gather and analyze such information must be offset by a decrease in drilling expenditures, an increase in drilling efficiency and an increase in safety. As drilling technology moved the pursuit of hydrocarbon resources into highercost offshore and hostile environments, intentionally deviated boreholes required information such as azimuth and inclination that could not be derived by surface instruments. Survey instruments, either lowered on a sand line or dropped into the drill pipe for later retrieval, to some degree satisfied the requirements but consumed expensive rig time and sometimes produced questionable results. For many years researchers have been looking for a simple, reliable measurement while drilling technique, referred to by its abbreviation MWD. As early as 1939, a logging while drilling (LWD) system, using an electric wire, was tested successfully but was not commercialized [89,90]. Mud pulse systems were first proposed in 1963 [91,92]. The first mechanical mud pulse system was marketed in 1964 by Teledrift for transmitting directional information [93]. In the early 1970s, the steering tool, an electric wire operated directional tool, gave the first real-time measurements while the directional buildup was in progress. Finally, the first modern mud pulse data transmission system was commercialized in 1977 by Teleco [94]. State-of-the-art surveys of the technology were made in 1978 [95], in 1988 [96-981, and in 1990 [99]. A problem with the early MWD mud pulse systems was the very slow rate of data transmission. Several minutes were needed to transmit one set of directional data. Anadrill working with a Mobil patent [loo] developed in the early 1980s a continuous wave system with a much faster data rate. It became possible to transmit many more drilling data, and also to transmit logging data making LWD possible. Today, as many as 16 parameters can be transmitted in 16 s. The dream of the early pioneers has been more than fulfilled since azimuth, inclination, tool face, downhole weight-on-bit, downhole torque, shocks, caliper, resistivity, gamma ray, neutron, density, Pe, sonic and more can be transmitted in realtime to the rig floor and the main office. Steering Tool MWD Technology Up until 1970 all directional drilling was conducted using singleshot and multishot data. The normal procedure was: a. drill vertically in rotary to the kick-off depth; b. kick-off towards the target using a downhole motor and a bent sub to an inclination of approximately 10';
