The SonicScope multiple LWD service delivers real-time multipole sonic information for advanced drilling optimization and formation evaluation.

Schlumberger has released the SonicScope* 475 multipole sonic-while-drilling service, a new logging-while-drilling (LWD) service that provides multipole measurements for consistent and reliable delivery of compressional and shear data in all environments. This service has 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, a crucial element in 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 Romania, offshore Black Sea, SonicScope was successfully used on two horizontal wells to deliver measurements for geomechanical model interpretation. “The service’s complete and complex investigation enabled us to isolate faults, select fracturing stages and identify the position of packers to plan the multistage hydraulic fracturing completion,” said Rodica Cataraiani, head of reservoir management, Petrom SA. “Production increased from 110 boe/d in 2008 to the record stable 900 boe/d.”

Also, 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.
