MicroScope 475 provides key information for formation
evaluation, well placement and fracture identification
BAHRAIN, March 6, 2012-Schlumberger announced today the
introduction of the MicroScope* high-resolution resistivity
and imaging-while-drilling service. On a single collar,
this logging-while-drilling service provides
high-resolution laterolog resistivity and full borehole
images in conductive mud environments.
"Optimal placement of the borehole in the reservoir,
accurate evaluation of formation properties and
identification of geological features that impact
producibility are key elements of a successful well," said
Andy Hendricks, president, Drilling & Measurements,
Schlumberger. "This service, already successful in more
than 150 jobs across 10 countries, addresses these
challenges in unconventional shale plays, carbonate and
MicroScope technology has been deployed worldwide. In a
tight gas carbonate reservoir in Asia, MicroScope
measurements facilitated formation evaluation and clearly
identified and defined the structural dips, faults and
fractures along the horizontal section in a complex, thin,
dolomite gas reservoir. The well was completed with an
initial gas production of 120,000 m3/d, which exceeded the
"The application of MicroScope in this challenging thin
tight gas reservoir has helped us make accurate real-time
decisions while drilling," said Peng Hai Run, chief
geologist, PetroChina SWOGC. "The success of this well has
opened more opportunities to our company in developing the
thin target reservoirs."
In Wyoming, the service helped tap the potential of the
Niobrara formation in the Denver-Julesburg basin. Both
permeability and porosity in the Niobrara chalk are
relatively low and production is usually enhanced by
natural fractures. Keeping the wellbore within the highly
fractured layer required accurate real-time information to
guide steering decisions. MicroScope images facilitated
well placement and fracture analysis to optimize hydraulic
fracturing stage designs.
The MicroScope tool acquires focused laterolog resistivity
measurements and images at four different depths of
investigation, with azimuthal sensitivity. These
measurements are essential for calculating reserve
estimates, placing horizontal wells and optimizing
