OnTrak Integrated MWD and LWD service
Overview
OnTrak Integrated MWD and LWD service
Maximize production with accurate characterization
of the reservoir in extreme HP/HT conditions
Applications
„„HP/HT
environments
„„Offshore
development
and exploration wells
„„Extended-reach
The OnTrak service delivers high quality log data in conjunction with gamma imaging, providing a more accurate
picture of what is occurring downhole.
„„Horizontal
„„Wells
wells
wells
that require geosteering
Features and Benefits
„„HP/HT
capability
–– Reaches reservoir targets
with minimal risk in hightemperature environments
„„Accurate
and reliable directional
measurements, including deep-reading
propagation resistivity and eight
compensated resistivity curves with
wireline quality
–– Maximizes production with
immediate identification of bed
boundaries and formation dips
„„Bore
and annular pressures with
flow on and off
The OnTrak service provides the real-time data that can be transmitted to your computer through the
Baker Hughes WellLink RT service.
The Baker Hughes OnTrak™ measurementwhile-drilling (MWD)/logging-while-drilling
(LWD) integrated service optimizes drilling
operations with accurate evaluation data
to locate and stay in the sweet spot,
closely monitoring implied pore pressures
to drill ahead safely. It provides accurate
characterization of the reservoir as an
alternative to wireline services, reduces
cost and safety risk, and acquires accurate
measurements to determine optimal
completion and production operations.
Along with pressure and dynamic monitoring,
this service provides a better understanding
of the actual well position. The integrated
design provides increased reliability and
fewer connections, and optimizes sensor-tobit spacing to complement directional control
with critical real-time data collection.
Our OnTrak service is rated for the most
extreme high-pressure/high-temperature
(HP/HT) environments, and can withstand
temperatures up to 350°F (175°C) and
pressures up to 30,000 psi (2068 bar).
–– Provides accurate equivalent density
circulation evaluation while drilling,
which leads to early identification
of potential drilling problems and
enables real-time decision making
„„Dual
gamma ray measurements
–– Supports excellent structural
interpretation, even in naturally
low radioactive formations
„„Vibration
and stick/slip measurements
–– Minimizes downtime through
optimized drilling parameters
„„Fast
two-way communication between
surface and downhole
–– Reduces drilling risk using real-time
downhole information
When combined with near-bit inclination from our AutoTrak™ rotary
closed-loop system, positional certainty is increased. With the OnTrak
service, steering decisions can be executed rapidly and precisely to
maximize reservoir exposure and production. Using the OnTrak service
results in accurate well placement and a smoother wellbore, which
optimizes completions and reduces the risk of wellbore instability.
The OnTrak service provides an array of integrated
measurements, including
„„Full inclination and close-to-the-bit azimuth
„„Deep-reading propagation resistivity that delivers eight
compensated resistivity curves of wireline quality
„„Dual azimuthal gamma ray sensors that allow bed boundary
identification and formation dip determination
„„Vibration and stick/slip (VSS) monitoring that provides realtime measurement of the full downhole dynamic environment,
allowing real-time optimization of drilling performance
„„Bore and annular pressure in real time with flow on, which
enables early identification of potential drilling problems
Additionally, the Baker Hughes aXcelerate™ high-speed mud-pulse
and wired-pipe telemetry service can be combined with the OnTrak
service and all other LWD services to deliver a clearer picture
of the downhole environment. These integrated MWD and LWD
services ultimately enable you to drill farther, faster, and safer.
To learn more about how our OnTrak integrated MWD and
LWD service can help you maximize production with more
accurate characterization of the reservoir, even in extreme
HP/HT conditions, contact your Baker Hughes representative
