DELIVERING RESULTS
An Industry First for
Logging While Drilling
Our GeoTap® IDS sensor is revolutionizing
the industry by allowing downhole capture,
identification and surface recovery of
representative fluid samples during the
drilling process. Built on the acclaimed
GeoTap formation pressure tester
platform, the GeoTap IDS sensor delivers
real-time reservoir characterization
and helps eliminate the time and cost
of wireline sampling.
MEETING THE DEEPWATER CHALLENGE Deepwater exploration and
development present some of the industry’s biggest challenges and greatest
potential rewards. Operators are increasingly turning their attention to
unexplored or underdeveloped deepwater areas to access additional
hydrocarbon resources. High temperatures and/or high pressures are often
found in these uncharted territories, presenting complex and unique challenges.
Halliburton has invested heavily in research and development to deliver tools
and technologies for deepwater wells in increasingly deeper, hotter and
higher-pressure environments.
DRILLING ADVANCES Our Sperry Drilling product service line has
an unmatched offering in high-temperature drilling with its unique
high-temperature motors and SOLAR™ Geo-Pilot® high-temperature rotary
steerable system. Sperry has also successfully deployed the 24-inch Geo-Pilot
system, which broadens our capabilities in deep water. Furthermore, it has
delivered record performances with no nonproductive time during Geo-Pilot GXT
rotary steerable runs in both Australia and the North Sea. Sperry has also
added extreme high-temperature directional capability through the acquisition of
TurboPower, resulting in the most comprehensive portfolio of high-temperature
drilling tools in the industry.
FORMATION EVALUATION ADVANCES In 2011, Sperry Drilling completed
successful field testing of the GeoTap® IDS sensor, which, deployed via a
logging-while-drilling (LWD) assembly, takes fluid samples and pressure tests
during the drilling process, thus avoiding the requirement for costly wireline
sampling runs after the well is drilled. During field testing, the customer drilled
for six days with the tool while capturing more than 50 formation pressure and
fluid tests. This resulted in almost 80 hours of rig time saved and the cancellation
of a competitor’s wireline job. With the GeoTap IDS sensor, samples were taken
within hours of drilling the formation, reducing the likelihood of borehole
damage and producing a less-contaminated sample. Sperry also successfully
field tested its XBAT™ sonic tool, the first acoustic LWD tool to produce azimuthal
images of the formation, enabling real-time geosteering to ensure accurate
well placement. Both of these technologies enable operators to make decisions
more quickly while minimizing risk and saving drilling time.
