Schlumberger offers new drilling service - Offshore

HOUSTON – Schlumberger has released its new SonicScope 475 multipole sonic-while-drilling service. This logging-while-drilling service gives multipole measurements to deliver compressional and shear data.

SonicScope has a dedicated mode to acquire Stoneley waveforms while drilling to assure high-quality data before washouts can develop, says Schlumberger. The compressional and shear data in combination with the Stoneley wave acquisition fosters assessment of rock mechanics and characterization of fractures.

In an offshore Black Sea project in Romanian waters, Schlumberger says SonicScope was successful on two horizontal wells at delivery of 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."

“Advanced multipole sonic-while-drilling data help to significantly reduce drilling uncertainties providing critical inputs for real-time drilling geomechanics evaluation, particularly in deepwater operations," said Andy Hendricks, president, Schlumberger Drilling & Measurements.
