units win five Hart's awards

HOUSTON, Texas — Three product service lines
of Halliburton subsidiary Halliburton Energy Services, Inc. and
two joint venture companies in which it holds an interest have won
Hart's E&P meritorious engineering awards for 2003.
Hart's E&P presented the awards today at the Offshore Technology
Conference in Houston.
"These awards represent the hard work and dedication of Halliburton
employees," said John Gibson, president and chief executive
officer of Halliburton's Energy Services Group. "It is an honor
for our technology to be recognised as the best. Halliburton employees
are dedicated to developing, perfecting and championing technology
that adds value to our customers' assets and increases our value
to the industry."
Halliburton technologies won in several categories. Baroid's ACCOLADE
drilling fluid won in wellbore construction systems; Sperry-Sun's
GeoTap formation tester in subsurface individual; Trapped Pressure
Compensators, in completions individual equipment; WellDynamics'
Digital Hydraulics in completions systems (WellDynamics is a joint
venture between two Halliburton subsidiaries and Shell Technology
Ventures BV); and Subsea 7's GoFlo flow remediation system in remediation
systems. (Subsea 7, Inc. was formed as a result of a combination
of the subsea business and assets of Halliburton and of DSND Coreco,
Inc).
Baroid's ACCOLADE drilling fluid is a revolutionary synthetic-based
fluid (SBF) system that has already achieved several "firsts."
The unique ester/ internal olefin blend-based fluid system is the
first fully emulsion-based SBF that contains no commercial clay
or lignite additives; and it is the first SBF to consistently provide
the rheological control necessary for safe, efficient deepwater
drilling operations where slim pore pressure/fracture gradient margins
and cold temperature ranges are present.
These outstanding attributes of the ACCOLADE system have consistently
reduced fluid loss, which has resulted in a significant reduction
of overall drilling expenses for numerous operators in the Gulf
of Mexico. In its first year alone, more than 700,000 feet have
been drilled with the ACCOLADE system.
Sperry-Sun's GeoTap Formation Tester is an integral component to
the logging-while-drilling (LWD) sensor cadre that measure in-situ
subsurface formation pore pressure on demand during the drilling
process. Pressure tests are achieved in five to seven minutes.
The GeoTap system is the first successful while-drilling type formation
tester to accomplish subsurface pressure measurements using a downhole
hydraulics and single pad/probe design.
Unlike other designs, which use hydraulic or inflated packers and
cannot take measurements with pumps on, the GeoTap system design
fulfills a long awaited measurement in a LWD environment that enables
well operators to take a significant step towards total wireline
replacement with pumps on or off.
A compelling aspect of this while-drilling service is that with
this new capability, estimates of formation pressure can be made
near the bit, which provides drilling engineers, reservoir engineers,
and petrophysicists critical information during the drilling process.
Halliburton's Trapped Pressure Compensator is a sealed, nitrogen-filled
chamber installed in the tubing string and inserted inside the casing
of a well so that pressure created by trapped annular completion
fluid neither ruptures nor collapses the casing.
In the past, sub optimal completion methods were performed because
trapped annular fluid pressures required either expensive, high-grade
casing or heavier casing with reduced internal diameter. The Trapped
Pressure Compensator conquers this problem.
Packers can now be set in optimal positions using larger, less
expensive casing and tubulars to significantly increase production
rates. By ensuring that trapped annular pressures never reach critical
limits, rupture and collapse of tubulars and lightweight production
casing is avoided, preventing the exposure of unprotected formations
behind the casing to completion fluids and exposure of the surface
casing to dangerous pressures.
WellDynamics' Digital Hydraulics is a closed-loop, hydraulic well
control system that uses the presence or absence of pressure to
communicate between a surface controller and downhole tools.
Based on this concept, the Shell/Halliburton joint venture designed
a Smartwell intelligent completion system that uses three hydraulic
control lines to independently manage up to six flow control devices.
Each tool can be hydraulically pressurised from the surface in
either direction, open to closed or closed to open, requiring no
downhole springs or gas charges.
Subsea 7's GoFlo flow remediation system, a joint development of
Halliburton and Subsea 7, Inc., is a unique solution to flowline
blockage remediation. The system uses composite coiled tubing that
is designed to be neutrally buoyant in flowline fluids.
This buoyancy removes a significant amount of the friction associated
with steel coiled tubing and enables the system to reach significant
distances. The most innovative aspect of the system is the use of
neutrally buoyant composite coiled tubing, the transmission of hydraulic
power over long distances and the ability to adapt the system for
real time inspection of pipelines.
The Hart's Meritorious Awards for Engineering Innovation, established
in 1971, honor the world's best new tools and techniques for finding,
drilling, and producing oil and gas wells.
Entries are judged on their innovation of concept or design, their
ability to solve a real, practical oilfield problem and their potential
for improving profitability, safety or efficiency.
The judging committee is composed of experienced industry personnel
from around the world with respected engineering backgrounds and
oilfield expertise.
Halliburton, founded in 1919, is one of the world's largest providers
of products and services to the petroleum and energy industries.
The company serves its customers with a broad range of products
and services through its Energy Services Group and Engineering and
Construction Group business segments.
