A new logging-while-drilling (LWD) tool offers high-quality sonic measurements over a wide range of formation types. The compressional wave slowness measurement provided through the service approaches or exceeds wire line quality and allows more complete formation evaluation. LWD sonic data are available at the surface only a few minutes after the bit penetrates a formation, enabling timely analysis of formation properties without having to wait hours, or sometimes days, for the acquisition of similar data by wire line logging. This long-spaced sonic tool has a rugged construction and special electronics which contribute to reliable operation and a wide measurement range. More than 49,000 ft of hole have been logged and over 1,400 hr of sonic waveforms have been recorded with the new tool worldwide. The tool has produced logs in the acoustically fast, hard-rock formations of the North Sea and the slow, soft-rock formations of the Gulf of Mexico.
