Cameron designed the FC wellhead system to meet all operator's
To satisfy the operator's requirements, Cameron engineers in Maracaibo,
Venezuela, developed the FC fast-connect HT wellhead system, rated 0–650
degF at a maximum pressure of 3,000 psi. Special software simulated rigorous
testing at high temperatures before the physical wellhead system was
manufactured. A unique feature of this custom wellhead system is that the
thermal expansion takes place internally through the casing hanger, eliminating
the use of expansion joints.
Designed for both high- and low-temperature applications, FC wellhead
system components are installed through the BOP stack, minimizing rig time. A
segmented landing base with holes facilities observation of returns and
performance of top job cementing, resulting in further time savings. An
internal backpressure valve helps to ensure well control while the drilling rig
moves off location.
Cameron leveraged its ongoing R&D, as well as extensive experience
in designing seals for custom applications, and worked with PetroMiranda to
design robust seals for the FC wellhead system that would withstand the extreme
temperatures and corrosive environments expected. Stringent qualification tests
and validations were carried out to ensure the quality and performance
consistency of the seals.
Customer saved USD 1.2 million in one year
Wellhead installation time was just 8 hours instead of the 24 hours
typically required for a conventional wellhead—a 67% reduction. For the
40 wells planned for the year, at a rig rate of USD 45,000/day the shorter
installation time represented a savings of USD 1.2 million. In addition, the FC
wellhead system enabled PetroMiranda to reduce completion time from 40 days to
20–30 days per well. As a result, the operator elected to use the FC
system on all its heavy oil wells.
