Arctic Directory: SLB has new multipole sonic-while-drilling service

Schlumberger said Feb. 3 that it has released the SonicScope 475 multipole sonic-while-drilling service. This new logging-while-drilling service provides multipole measurements to consistently and reliably deliver compressional and shear data in all environments. SonicScope 475 is the only service in the industry with a dedicated mode for acquiring Stoneley waveforms while drilling to ensure high-quality data before washouts can develop. SonicScope compressional and shear data, with the Stoneley wave acquisition, enable the assessment of rock mechanics and characterization of fractures. This is crucial especially in the North American shale plays for designing complex completions to optimize future production. In addition, a while-tripping mode provides multipass analysis and top-of-cement evaluation. In a 100-well field test campaign, the new service supplied high-quality multipole data comparable to wireline sonic reference logs, even in highly damaged and unstable formations. SonicScope 475 was run in shale plays for horizontal well evaluation for enhanced completion design and optimization. In deepwater wells, SonicScope has been run successfully to enhance real-time pore pressure monitoring, wellbore stability and seismic tie-in.
