Casing standards.
(c) Used casing may be approved for use as
surface, intermediate, or production casing but shall be pressure tested after
cementing and before continuation of drilling.
A passing pressure test is holding the anticipated maximum pressure to
which it will be exposed for 30 minutes with not more than a 10% decrease in
pressure.
Question:
Used casing was installed and cemented for
the intermediate string of a well under the old regulations. No pressure
testing was conducted because this requirement was not in place under the old
regulations. The operator just drilled
the production hole and is now running production pipe. Do they need to conduct
the pressure test?
Question:
Pressure testing of the intermediate casing must
be conducted.
