Section 78.404 - Maximum storage pressureA gas storage reservoir operator, who has not requested approval of a maximum storage pressure for a gas storage reservoir, shall request, by February 15, 1995, Department approval of a maximum gas storage reservoir pressure in accordance with the following:
(1) The maximum shut-in wellhead pressure (psig) may not exceed the highest shut-in wellhead pressure (psig) found to exist during the production history of the reservoir, unless a higher pressure is established through testing of caprock and pool containment. The methods used for determining the higher pressure shall be determined in conference with the Department in accordance with section 501 of the act.(2) If the original discovery shut-in wellhead pressure (psig) is not known, or the highest production shut-in wellhead pressure (psig) is not known, or a higher pressure has not been established through a method as approved by the Department as established in paragraph (1), the maximum storage reservoir pressure shall be limited to a freshwater hydrostatic gradient.
