Description |
The objective of this study is to analyze industry’s
use and qualification of elastomers in HT drilling applications, assess
elastomer failures, review HPHT elastomer compounds under development,
and review procedures that verify field compliance of NACE MR-01-75.
WEST will address this technology
gap by studying the following items:
-
Review industry standards for
qualification of BOP elastomers for High Temperature (HT) service and
address their adequacy. Design verification standards will be
scrutinized and confirmed as appropriate.
-
Categorize and discuss HT
elastomer limitations and failure modes experienced. Compare and contrast
rating methodologies used with industry standards above.
-
Review elastomeric compounds
available and under development to determine if suitable elastomers
are or will be available for the conditions under study.
-
For compounds under development,
work with industry to ensure tests planned adequately validate
the suggested technology.
-
Research and report the
differences between appropriate applications of HT elastomers on
surface stacks vs. subsea
stacks.
-
Discuss procedures that verify
field compliance to NACE MR-01-75 (ISO 15156). Include frequently
accepted compromise testing as well as considerations and
limitations for suitability when
not in compliance.
