The SonicScope multipole sonic-while-drilling service is a logging-while-drilling service that provides multipole measurements to deliver consistent and reliable compressional and shear data in all environments. In a 100-well fieldtest campaign, the service supplied high-quality multipole data comparable to wireline sonic reference logs, even in highly damaged and unstable formations. Multipole service was run in tight gas reservoirs, including shale gas, for horizontal-well evaluation for enhanced completion design and optimization, and in deepwater wells with real-time porepressure monitoring, wellbore stability, and seismic tie-in.
