312 IAC 29-20-3 - Specifications for well casing
Authority: IC 14-10-2-4; IC 14-37-3
Affected: IC 14-37; IC 25-39-4
Sec. 3.
(a) The owner
or operator shall determine the type and grade of casing used in a well for oil
and gas purposes according to standard industry practices that take into
consideration:
(1) the anticipated maximum
pressure the casing will be exposed to during the life of the well;
and
(2) factors in the well that
could reduce the integrity of the casing during the life of the well including:
(A) harsh chemical environments;
and
(B) the potential for
mechanical damage.
All casing shall meet the requirements of this section.
(b) Except as provided in subsections (c) and
(d), new wells for oil and gas purposes shall be constructed with steel casing
that meets at least one (1) of the following minimum requirements:
(1) "Specification for Casing and Tubing",
Ninth Edition, published by the American Petroleum Institute (API), July
2011.
(2) Casing shall have an
internal pressure rating at least twenty percent (20%) greater than the
anticipated maximum pressure to which the casing will be exposed determined as
follows:
(A) For new or reconditioned pipe,
the mill test pressure may be used.
(B) For used pipe the operator shall pressure
test the casing at a pressure at least twenty percent (20%) greater than the
anticipated maximum pressure to which the casing will be exposed for a minimum
of thirty (30) minutes with a pressure drop of no more than ten percent
(10%).
(c) A
water supply well used to provide water in connection with an enhanced recovery
well that is drilled to a depth at or above the depth of the lowermost
underground source of drinking water may be constructed with casing
manufactured of material other than steel provided the casing meets the
specifications set forth at IC 25-39-4and
312 IAC 12-3.
(d) The use of fiberglass casing in the
construction of a well for oil and gas purposes may be authorized by the
division director upon written request from the owner or operator that includes
the following:
(1) A statement of the reason
for the use of fiberglass casing.
(2) A demonstration that:
(A) the casing meets the requirements for
fiberglass well casing in "Specification for Fiberglass Casing and Tubing", 3rd
Edition, published by the American Petroleum Institute, (API) May 1987;
and
(B) the casing will provide
protection equivalent to steel casing according to the requirements of
subsections (a) and (b).
