Development of sophisticated formation evaluation instrumentation for use while drilling has led to a stratification of while-drilling services. Measurements while drilling (MWD) comprises measurements of mechanical parameters like weight-on-bit, mud pressures, torque, vibration, hole angle and direction. Logging while drilling (LWD) describes resistivity, sonic, and radiation logging which rival wireline measurements in accuracy. A critical feature of LWD is the rate that data can be telemetered to the surface. Early tools could only transmit 3 bits per second one way. In the last decade, the data rate has more than tripled. Despite these improvements, LWD tools have the ability to make many more measurements than can be telemetered in real-time. The paper discusses the development of this technology and its applications.
