Ind. Admin. Code tit. 312, r. 29-25-11 – Maintenance of well head, fittings, and equipment

Sec. 11. (a) An owner or operator shall install and maintain a well head rated to withstand maximum expected downhole pressures on each well completed for oil and gas purposes except:

(1) when removal of the well head is necessary to perform maintenance on the well or to plug the well; and
(2) when other measures are taken to maintain control of the well at all times and prevent the release or discharge of gas or fluids from the well.

(b) Each well head and associated valves, fittings, and equipment shall be maintained in a leak-free condition and equipped with sufficient valves and fittings to monitor casing and tubing pressures.

(c) The well head on each Class II well shall be configured to include a one-fourth (1/4) inch female fitting, with shut-off valve, to allow monitoring of the annulus between the production casing and the injection tubing. An additional one-fourth (1/4) inch female fitting, with shut-off valve, shall be installed on the tubing to measure the injection pressure.

(d) Any well that is not equipped with casing that has been circulated with cement as required under 312 IAC 29-20 shall be configured to include a one-fourth (1/4) inch female fitting, with shut-off valve, to allow monitoring of the annulus between the production casing and the surface casing as required under 312 IAC 29-20-14.
