THE world's leading specinlist in Solid
Expandable Tabular (SEf) solutions,
Enventure
Globol Technology, hus
opened an office in Australia as part of
e continuing global expansi.on.
During a recent visit to Australia, Enventure
GT's presidentand ceo,Bob Hinkel, told Oil &
GasAustralia that the new Perth office will be
a key componentof the company's significant
move into the AustralAsian region.
The company has named Andrew
Sutherland to head up the local operation
and he will be responsible for marketing
Enventure GT in Australia, New Zealand and
PapuaNew Guinea.
As well as reporting to Enventure GT's
head offrce in Houston, Mr Sutherland will
also have close links with the company's
other operationsin Kuala Lumpur (Malaysia),
Jakarta(Indonesia)and Beijing (China) in this
region.
Launched in 1998, Enventure GT was
created by Halliburton Energy Services and
Shell Technology Ventures as a vehicle to
further the exciting breakthroughs they had
made in SET technology.
Those developments began in the early
1990s when Royal Dutch Shell began
investigating the possibility of expanding
solid oilfield tubulars downhole. The original
concepttest was performed in The Hague, but
the pipe was constructedof steelsimilar to that

used in the crumple zone of an automobile,
and the joints of the pipe were welded
together.
At the end of 1997, Shell Technology
VenturesInc. and Halliburton Energy Services
began exploring the possibility of forming a
new limited liability company whose initial
focus would be the developmentand commercialisation of expandabletubular technology.
The new company would be funded and
managed equally by the two partners. As
work progressed toward forming the joint
venture, proof-of-concept tests performed at
Halliburton's Houston Technology Centre in
September 1998 demonstratedthe feasibility
of expanding oilfield country tubulars.
Enventure Global Technology was born in
December1998.

development
continued
throughout early 1999, with key milestones
being achievedin March of that year:
. surface expansion of over 600 feet of 3
Il2-rnclt coiled tubing; and
. full-scale rig tests of the 13 3/8-inch by
16-inch openhole system.
In May 1999, Enventure introduced three
product lines at the Offshore Technology
Conference in Houston - the Enventure
OpenholeLiner (OHL) System;the Enventure
Cased-Hole Liner (CHL) System; and the
VersaFlex Expandable Liner Hanger (ELH)
System.

Since that time, SET systems have been
installed in both openhole and cased-hole
wellbores in a variety of environmentson land
and offshore in deepwaterand ultra-deepwater
globally.
As of October 2004, Enventure has
completed over 272 installations and has
expandedmore than 86 km for 63 customers
in 20 countries.
The company has undertaken work for
some of the biggest names in the oil and
gas sector, including Shell, ChevronTexaco.
Uncical, Sinopec, Conoco Phillips, Talisman
and Peffonas.
While it has been contractedby Australia's
BHP Billiton and Santos for international
work, Enventure GT has yet to perform its
unique servicesin Australia - something that

EnventureGT's SET Technologyminimises
.ieep drilling issues such as telescoping
r borehole tapering before reaching the
3eologicalobjective.
Additionally, SET Solutions can mitigate
\evere lost circulation, addresschallenges to
horehole stability and repair old casing strings
hv increasing their burst strength.
The technology may also revive plugged
and abandoned wells. SET Technology
minimises the loss of inside casing diameter,
making the technology applicable as a
contingency casing, drill liner or cased-hole
liner in workover or completion operations.
The innovative, cost-reducing technology
can be used for: well slimming; remedial
operations; window exit applications; and
horizontal well applications.
TI{E FUTURE
Aside from its recent significant global
expansion, Enventure GT has also continued
to make further breakthroughs in SET
technology. One of these developments is its
patented MonoDiameter application.
While planned. SET Systems reduce the
telescoping effect in traditional well design,
the MonoDiameter System will eliminate
telescoping altogether, slimming down the top
of the well while increasing well diameter at
TD. The MonoDiameter System exhibits the
ultimate in diametric efficiencies - a constant
ID from the top of the well to TD.
The MonoDiameter Process over-expands
the junctions of the nested expanded casing
liners, resulting in a single-diameter wellbore.
Nesting sequentially installed expandable
casing strings can decreasethe reduction of
a typical hole size by 50 per cent and enable
drilling to continue as deep as necessaryto
reach the payzone.
The MonoDiameter application is a feature
of a recently signed agreementbetween Norsk
Hydro and Enventure GT that incorporates
SET technology into the Norsk Hydro's Tekno
2005 programme to develop new reserves and
reduce development costs in its Norwegian
offshore fields.
"This agreernent provides
a unique
opportunify for a MonoDiameter application,"
said Mr Hinkel. "Norsk Hydro recognised
MonoDiameter technology as a viable means
in which to accessreseryes cost effectively by
capitalising on structures and facilities that are
already in place."
The cooperative effort between Hydro
and Enventure GT consists of the fust field
application of the MonoDiarneter System
in combination with Hydro's multi-well,
extended-reachfield development scenario.
These installations will be fit-for-purpose
applications to maximise recovery of reserves
at distancesexceeding 10 km from the drilling
structures. One potential candidate is the
Ormen Lange field. Production from this field
is expected to supply the UK with 20 per cent
of its total sas demandbv 2007.l
