Tenaris has pushed the limits of its high pressure/high
temperature (HP/HT) technology, and through precision in
execution in testing, delivery, running and expert services,
generated outstanding results for its work on Total's Culzean
project.
According to the supplier of tubes and related services for the
world's energy industry and certain other industrial applications
the Culzean gas field is located in the challenging waters of the
North Sea, about 145 miles off the coast of Aberdeen.
The field began production in June and is anticipated, at peak,
to provide five percent of the United Kingdom's gas demand.
Tenaris supplied TenarisHydril Blue Max and TenarisHydril Blue
Heavy Wall connections, and Dopeless technology for the project's
complex wells in water depths of 90 meters to production zones
located about 4,500 meters below the sea level with bottom hole
pressure of 13,500 psi and bottom hole temperatures of 180C.
"This was an incredible undertaking in extreme downhole
conditions of high pressure and threat of corrosion. We achieved
amazing results, carrying out industry-first testing for our
products, proving the robustness of our technology, minimizing
risks, ensuring reliability and optimizing performance," said
Gabriel Podskubka, Tenaris President, Eastern Hemisphere.
To enhance running times, the Culzean team opted to run double
stands. The running of 2,200 joints of TenarisHydril Blue Max and
Blue Heavy Wall Dopeless connections, with each double joint
weighing up to 4.25 metric tons, was a success, with 99.6 percent
of the connections torqued to the required value on the first
make up.
The use of Tenaris's dry, multifunctional coating, Dopeless
technology, further enhanced the stand's robustness in make up,
while offering the customer the environmental and safety benefits
the product offers due to the absence of compound, making for a
cleaner rig site, as well as generating total pipe cost savings.
To manage the rigorous technical product specifications required
and delivery dates, Tenaris also provided its logistics solution
based Rig Direct services, strategically coordinating
manufacturing and testing with its local and global teams.
Expert services included technical consulting, pipe management,
as well as a dedicated field services expert at the rig site to
support running operations.
Tenaris was first awarded the long-term contract to supply pipe
casing and related services for Culzean in 2015 from Maersk Oil,
which was acquired by Total in 2018.
