(A) Plugging operations on a dry hole or lost hole shall commence immediately upon abandonment of the hole. A lost hole shall be considered abandoned when the decision has been made that completion of the well is not feasible. Such well shall be plugged prior to the skidding of the drilling rig to an alternative location. A dry hole shall be considered abandoned when the decision has been made not to complete the well. Exceptions may be granted by oral or written permission of the chief.
(B) Prior to commencement of plugging operations for a dry hole or lost hole, the owner, or his authorized agent, shall furnish the inspector with a record of the depth of the top and the base of formations penetrated during the drilling of the well, the depths where oil, gas or water were encountered, and a record of any casing present in the well. If reasonably available, the information furnished shall include a copy of the geophysical, electrical, or mechanical log and/ or the drilling contractors report. Based on the furnished information the inspector shall approve a plugging program in accordance with rules 1501:9-11-01 to 1501-9-11-13 of the Administrative Code and plug emplacement methods and plugging materials approved by the chief. When no records are available, the owner, or his agent, shall make every reasonable effort to obtain sufficient formation and casing data on the well, to assist the inspector in determining the plugging procedure. Exceptions may be granted at the discretion of the chief.
(C) Plugging operations on each abandoned oil and gas well, abandoned brine disposal well, abandoned well used to inject fluids for the enhanced recovery of oil or gas, and abandoned well used to store hydrocarbons and all wells plugged back in order to inject into or extract fluids from a more shallow formation and abandoned well used for solution mining of minerals must commence without undue delay after production, extraction, or injection operations have ceased and shall proceed with due diligence until completed. Exceptions may be granted by oral or written permission of the chief.
