Schlumberger releases new sonic while drilling service

Friday, February 4, 2011

Schlumberger has released a new  multipole sonic-while-drilling (LWD) service known as SonicScope 475.

The service provides multipole measurements for compressional and shear data in all environments and according to Schlumberger 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. 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 S.A. "Production increased from 110 boe/d in 2008 to the record stable 900 boe/d, bringing enormous value in this high cost offshore environment and securing long-term success for OMV Petrom."

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.
