The Baker Hughes FASTrak™ logging-whiledrilling (LWD) fluid analysis sampling
and testing service obtains accurate
formation pressure and formation fluid
samples while drilling. It combines three
distinct functions—accurate real-time
formation pressure tests, real-time in-situ
measurements of reservoir fluid properties,
and downhole capture and retrieval of
formation fluid samples. Pressure testing
provides important information concerning
fluid dynamics within the reservoir,
including mobility measurements and
predictions of productivity of the zone.
Conventional pressure-volumetemperature (PVT) analysis can delay
the decision-making process from weeks
to months, depending upon the logistics
involved in transporting a sample from
its acquired location to a PVT laboratory.
Because the FASTrak service samples,
tests, and analyzes in real time and
on-site, you can make critical decisions
regarding your reservoir right away,
with no delays and no downtime.
The FASTrak service includes sensors
that identify real-time density, viscosity,
refractive index, and sound/speed
measurements. These sensors provide
real-time fluid typing as well as real-time
cleanup monitoring.
By accurately sampling, testing, and
analyzing reservoir fluid properties, the
FASTrak service quickly helps in the
estimation of reserves in an oil reservoir
and helps predict its performance and
economics. The FASTrak service precisely
measures and reports PVT properties such
as bubblepoint pressure, gas/oil ratio,
viscosity, and other detailed composition
for analysis of well performance, material
balance calculations, reservoir simulation,
and production engineering calculations.
Determining the fluid properties by using
the FASTrak service can be essential in
petroleum reservoir studies, the design of
production equipment, and the estimation
of the recovery efficiency of a reservoir.
Features and Benefits
„„High-quality
fluid analysis,
representative fluid samples,
and formation pressures
–– Provides information on the
production potential of the reservoir
„„Baker
Hughes SmartPad™ and
SmarTest™ continuous-control
closed-loop systems
–– Provide highly accurate formation
pressure tests
„„In-situ
fluid analysis
–– Enhances critical decision making
based on fluid identification and
fluid typing during sampling
„„Sample
and pressure testing
while circulating
–– Reduces risk of differential
sticking of bottomhole assembly
„„Captures
up to 16 single-phase samples
–– Maximizes fluid volume recovered
in a single run
„„Chemical
resistant metallurgy
–– Collects representative fluid
samples for geochemical analysis
The FASTrak service stores fluid samples inside sample tanks
that are precharged with nitrogen to ensure sample integrity.
Each carrier can hold four sample tanks, and as many as four
carriers can be assembled per trip to capture 16 fluid samples.
The accurate gradient analysis provided by the FASTrak
service yields information on fluid type and density of the
formation fluids. Pressure testing by the FASTrak service in
an LWD environment optimizes safety and drilling efficiency
while controlling overbalance and equivalent circulating
density. Representative fluid samples analyzed by the FASTrak
service provide information on production potential of the
reservoir, the design and development of production facilities,
and completion and development costs. Before the capture
and retrieval of fluid samples, it must be determined in real
time what fluid is being pumped through the tool, and the
FASTrak service makes that possible.
