Downhole Fluid Analysis with Lab-Quality Results
ICE CoreSM Fluid Analysis Service
Until now, downhole fluid analysis has been limited. Optical analyzers could tell you when your sample was pure enough to collect, but rarely could they tell you which fluid components were present and in what proportions. The revolutionary, new Halliburton ICE Core™ technology can give you that information. It is available in the Integrated Characterization Section (ICS) of Halliburton’s proven Reservoir Description Tool (RDT™ tester).
How ICE Core Technology WorksLight shines through downhole fluids and then through ICE Core
sensors. Each sensor is programmed to recognize the chemical
nature – or optical fingerprint – of a specific fluid component,
such as methane, ethane, propane, aromatics, saturates or water.
Measuring the intensity of light passing through any one sensor
indicates the presence and proportion of a particular chemical
component within the overall fluid.
How ICE Core Technology DiffersICE Core technology relies on the ruggedness and simplicity of
photometric detection, not spectroscopy. As a result, ICE Core
technology does not require a computer to perform calculations on
an optical spectrum like competing systems. Each ICE Core sensor
is designed to respond specifically to the fingerprint of the selected
analyte using all of the useful information in the optical spectrum.
At Last. Downhole Fluid Analysis with Lab-Quality Results.Introducing ICE CoreSM fluid analysis service from Halliburton, a revolutionary new way to accurately analyze fluids downhole.

Identify Fluids that Other Tools Can’tICE CoreTM technology captures information
from the spectrum that other tools can’t
read. As a result, it can reliably identify
hydrocarbons plus many other fluid
components such as:
n CO2*n Asphaltenes*n Methanen Ethanen Propanen Water *n Saturatesn Aromaticsn Resins*n Gas/oil ratios (GOR)n H2S*

The ICS20 will take up to 20 ICE Core measurements downhole using a rotating wheel of selected sensors.
Wider RangeICE Core technology spans a broader optical range than
conventional downhole spectroscopy tools that analyze
only a limited portion of the spectrum (wavelengths up to
2100 nm). ICE Core technology measures wavelengths up
to 5500 nm where important fluid components like hydrogen
sulfide can be optimally characterized. Stronger, clearer and
more descriptive optical fingerprints are in the mid-infrared
portion of the spectrum where competitive technology simply
cannot make measurements.
More Reliable ResultsBecause ICE Core technology involves only direct measurement,
not a spectrometer, it is very reliable. The design and fabrication
of ICE Core sensors are very complicated processes, but using
them to analyze fluids downhole is relatively simple. The
essential components are merely a light source, the ICE Core
sensors and a detector.
Real-Time ResultsAs part of Halliburton’s field-proven Reservoir Description
Tool (RDT™ tester), ICE Core technology can provide surface
readouts in real time.
Field-Proven ResultsHalliburton has used ICE Core technology since 2012
with clients around the world, including customers in the
U.S., North Sea, Middle East, Latin America and Africa.
ICE Core technology yields results that correlate highly
with lab analysis. Gas-oil ratios and fluid densities have
been validated to within 14 scf/bbl and 1% respectively. The
technology has successfully analyzed fluids under conditions
that range from 3,000 to 20,000 psi, and from 150˚ to 350˚F.
Why Downhole Fluid Analysis?ICE Core technology tells you when reservoir fluids are
pure enough to collect. It also provides a valuable preview
of laboratory results. Fluid samples never get better than
when they’re downhole, whereas laboratory analysis can
have limitations:
n Turn-around time – It can take months or even years
to get lab results, delaying planners.
n Operational risks – Precious samples can get lost or
damaged in transit to the lab.
n Sample degradation – Contamination in collection tubes
can scavenge elements within samples, skewing results.
n Phase change – Loss of pressure and heat at the surface
can cause some fluid components to change phase and
come out of solution.
More Data from More ZonesClients may want to collect samples from a large number
of zones in a well, but may not have the capacity. ICE Core
technology can give clients insight into the fluid properties
whether or not physical samples are captured.
ICE Core technology enables you to analyze fluids from other
zones – without making additional runs. Analyzing samples
from more points within the well enables you to see if fluids
are stratified within your reservoir.
When drilling exploration or development wells, ICE Core
technology also provides valuable information about reservoir
connectivity. Knowing precisely what fluids are present enables
reservoir engineers to design a comprehensive production strategy.
ICE Core technology can give you valuable insight that helps
plan your completion and top-side facilities by collecting more
data from more zones.
