Current through Register Vol. 49, No. 6, June, 2024
RULE H-2:
WELL CONSTRUCTION, OPERATING AND
			 REPORTING REQUIREMENTS FOR CLASS II DISPOSAL AND ENHANCED OIL RECOVERY (EOR)
			 INJECTION WELLS
a)
		  No Class II Disposal or EOR Well, as defined in General Rule H-1 a) 1)
		  (hereinafter referred to as "Class II Well" for purposes of this Rule), for
		  which a permit has been issued in accordance with General Rule H-1, shall be
		  operated until well internal mechanical integrity has been established in
		  accordance with sub-paragraph o) below, and an authority for initial
		  commencement of injection operations is issued by the Director.
b) The permit holder shall provide notice to
		  the Commission Regional Office where the Class II Well is located, prior to
		  performing any well servicing activity, cementing, or any wireline logging
		  activities, so as to allow commission staff to be present to observe the
		  activity. Any well servicing which requires the resetting of the packer shall
		  require an internal mechanical integrity test be run in accordance with
		  subparagraph o) below, prior to re-commencement of injection.
c) All well records for newly drilled Class
		  II Wells shall be submitted in accordance General Rule B-5. Completion or
		  recompletion reports and wireline logs for all subsequent well servicing,
		  cementing or wireline logging activity performed on the well shall be filed no
		  later than fifteen (15) days after completion of these activities.
d) Following issuance of the permit to drill
		  and or operate a Class II Well, an annual fee of $100 per well shall be due
		  each July 1st for the life of the well until the
		  well is plugged.
e) Surface and
		  production casing requirements.
1) Class II
		  Wells shall be cased and cemented, in such manner that damage will not be
		  caused to any USDW, as defined in General Rule H-1 a) 5) (hereinafter referred
		  to as "USDW"), or oil and gas resources.
2) For newly drilled Class II Wells
A) Set and cement surface casing 250 feet
		  below the base of the lowermost USDW, and cement production casing to at least
		  250 feet above the proposed disposal zone; or
B) Set and cement surface casing fifty (50)
		  feet below the base of the lowermost formation utilized for a public water
		  system (see 40 CFR) in the area of the Class II Well, with a minimum of five
		  hundred (500) feet of surface casing required, and cement production casing
		  back to the surface.
3)
		  For existing wells converted to Class II Wells
A) Unless otherwise approved by the Director,
		  production casing in the existing well is required to be cemented to at least
		  250 feet above the proposed disposal zone. A cement bond (CBL), gamma ray (GR)
		  and density log (VDL) shall be required to verify the presence of the required
		  casing cement. The CBL should indicate at a minimum an 80% bond index over the
		  250 foot cemented interval.
B) If a
		  casing liner is required to provide well bore integrity above the required
		  production cementing requirements in subparagraph e) 3) A) above, the liner
		  must be set, at a minimum, below the cemented portion of the production casing
		  and cemented back to surface.
