New
Schlumberger sonicVISION tool delivers real-time measurements for
reduced drilling risks and costs
Posted: 17 May 2004
Schlumberger Oilfield Services introduced its sonicVISION sonic-while-drilling
tool that provides both enhanced real-time log data quality and
improved tool reliability and functionality resulting in increased
drilling efficiency and safety.
More than a decade of Schlumberger experience in sonic logging-while-drilling
(LWD) technology has resulted in an LWD tool that delivers high
quality, real-time acoustic travel time data, which provides operators
with the confidence they need to make critical well decisions in
today’s challenging drilling environments.
High-quality, real-time sonic data can be applied to many drilling
scenarios, including pore pressure prediction, drilling process
optimization, stress and rock strength determination, formation
gas and gas influx detection and bit-on-seismic positioning.
“Measurements acquired by the sonicVISION tool can significantly
reduce drilling risks and costs by providing critical formation
data in uncertain and challenging environments,” said Paal
Kibsgaard, president, Drilling & Measurements, Schlumberger
Oilfield Services. “Proprietary Schlumberger software turns
quality sonicVISION log information and other LWD measurements into
valuable drilling answers such as safe operating mud weight window.”
Improved confidence of the real-time measurements is made possible
by several features, including a real-time projection log, typically
only available in memory, which enables the sonic information be
labeled in realtime at surface and interpreted by a remote expert
if needed. Automatic station measurements done in a noise free environment
during connections and sent uphole sent in realtime for additional
quality control, wideband receivers and high-power transmitter further
improve the confidence of the real-time measurement.
Combinable with all Schlumberger LWD systems, the sonicVISION tool
is available in 6¾-in., 8¼-in. and 9-in. collar sizes
and has been run successfully in hole sizes ranging from 8-1/2 to
up to 30-in.
