Schlumberger Acquires Geomechanics Leader TerraTek, Inc.; Establishes New Geomechanics Laboratory Center of Excellence to Offer Services to Reduce Reservoir Risk through More Accurate Reservoir Characterization

Schlumberger today announced it has acquired TerraTek,
Inc., a global leader in geomechanics measurements and analysis.
TerraTek, with 80 people in the Salt Lake City office, will become the
Geomechanics Laboratory Center of Excellence for Schlumberger Data &
Consulting Services.
This acquisition brings together the expertise and knowledge base
of both companies to create a unique domain of expertise in
geomechanics measurements and analysis. Customers will benefit from
unparalleled services that can reduce reservoir risk and uncertainties
by delivering more accurate reservoir characterization.
"By integrating their knowledge of applied geomechanics core
evaluation with our expertise in petrophysics and geomechanics, we
will enhance the value of our services, particularly in the
unconventional gas reservoirs that will produce a greater proportion
of future world supply," said Chris Hopkins, president, Data &
Consulting Services, Schlumberger.
The Geomechanics Laboratory Center of Excellence will offer rock
mechanics evaluations, unconventional gas reservoir analysis,
large-scale drilling and completions performance testing, and
log-to-core integration.
"This is a significant step for our employees and our customers,"
said Sidney Green, chief executive officer, TerraTek. "As part of the
Data & Consulting Services group, our measurements and analysis of
rock properties can leverage the industry's leading petrophysical
technologies as well as provide substantial knowledge to further
develop advanced reservoir solutions."
Geomechanics analysis provides vital understanding of the behavior
of hydrocarbon reservoir rocks as they undergo the mechanical changes
associated with drilling and production activity.
