R 299.2358 Mud gas separator; burning of gas generated by mud gas separator; incinerator or flare installation; hydrogen sulfide concentration determination.

Rule 2358.(1) All of the following provisions apply to rotary drilling operations : (a) If a gas kick occurs, all returning drilling fluid shall be circulated through a mud gas separator. (b) All gas separated from the drilling fluid by the mud gas separator shall be routed to a properly engineered incinerator or flare that has an elevated discharge to the atmosphere and shall be burned unless the supervisor of mineral wells has approved an alternative method for handling the gas. (c) If gas is routed to the incinerator or flare from the mud gas separator, then the hydrogen sulfide content of the gas shall be determined by a permittee or the permittee's representative. The determination shall be made using colorimetric or length of stain tubes or other equipment designed to measure hydrogen sulfide concentrations and shall utilize a procedure approved by the supervisor of mineral wells or authorized representative of the supervisor of mineral wells. The results of the determination shall be entered into the driller's log. (2) Both of the following provisions apply to cable tool drilling: (a) All gas separated from other fluids shall be routed to a properly engineered flare or incinerator that has an elevated discharge to the atmosphere and shall be burned. (b) If gas is routed to the incinerator or flare, then the hydrogen sulfide content of the gas shall be determined by a permittee or the permittee's representative. The determination shall be made using colorimetric or length of stain tubes or other equipment designed to measure hydrogen sulfide concentrations and shall utilize a procedure approved by the supervisor of mineral wells or authorized representative of the supervisor of mineral wells. The results of the determination shall be entered into the driller's log.
