LEVERAGING YOUR DATA
You’ve invested in the use of downhole tools to measure and log your
casing integrity, to assist you in planning remedial work and in
preventing catastrophic casing problems. Casing damage can be costly,
in terms of lost production, repairs, environmental pollution or
accidents. Estimating what to repair when is key in reducing downtime
and maximizing field production.
There are various visualization tools to graph the log data and
produce 3D views of the casing surface. Plotting the geometry of the
casing provides a lot of information, but it does not provide an
indication of the remaining casing strength. Knowing where the stress
levels in your casing lie on the material’s stress-strain curve estimates
your factor of safety relative to the yield strength.
Reviewing the log data allows a determination of which damaged areas may
be critical to casing integrity. We use your multifinger imaging
tool (MIT) data to prepare finite element models of these critical
sections.
We work with you to quantify the loads these sections of casing
will be subjected to during your phases of operation, such as production,
packer unsetting and recovery. We apply finite element analysis (FEA) to
provide you with color plots of the estimated stresses the casing will
experience during these phases. You’ll receive stress plots estimating
the local factor of safety relative to the yield strength and tensile
strength of the casing material.
We bring to the table 30 years of FEA experience and provide a unique solution
to help you characterize your well casing and increase profitability.
Value
Across the spectrum of onshore wells to deepwater rigs, daily rates can be
measured in thousands of dollars to many hundreds of thousands of dollars,
and a well can cost millions of dollars to hundreds of millions of
dollars. Investing in leveraging your cased hole logs to provide pipe
stress estimates is sound engineering and good business practice.
WORLDWIDE SERVICES
We provide well pipe finite element analysis (FEA) services worldwide. We receive
your log data electronically and deliver your results report in PDF format.
EXTENSIVE EXPERIENCE
We have 30 years FEA experience.
In addition to analyzing oil field equipment, we have applied FEA to fuel
plant piping, wind turbines, robots, heavy equipment such as earth movers
and rock crushers, high-precision machining equipment, various medical
products, a vast array of vehicles including aircraft, marine, automobiles,
trucks and motorcycles, and aerospace projects including the International
Space Station.
