Rule 26-2-1.28 - PLUGGING AND ABANDONMENT Each abandoned hole or well shall be plugged by or on behalf of the owner, operator or producer who is in charge of the well and responsible therefore.
A. Schedule of Abandonment and Reporting on Form No. OGB 9-12-15-Z and Form No. 9-A. 1. Dry Holes All wells drilled for oil or gas and found to be dry prior to or after the effective date of this order shall be plugged within one hundred twenty (120) days after operations have been completed thereon or one hundred twenty (120) days after the effective date of this order, whichever is later, unless an extension of time is granted by the Mississippi State Oil and Gas Board following notice and hearing. A petition for inactive well status for a dry hole shall be accompanied by a duly executed "Inactive Well Status Report" (Form No. 9-A) requesting that the inactive well status of such well be extended for an additional period of time not to exceed twelve (12) months. Any such extension of inactive well status for a dry hole may only be approved by the Board for such additional period as the Board, in its discretion, may deem appropriate but in no event for longer than twelve (12) months. Any petition filed by an operator with the Board to extend a dry hole's inactive status must state the grounds for such extension (e.g., proof of the well's future utility.)
2. All Other Wells a. All wells wherein production operations or use as a service well have ceased on or after the effective date of this order shall continue to be reported on Form No. OGB 9-12-15-Z with the appropriate notation that the well is off production or no longer in use as a service well along with the date of last production or date the service well ceased to be used. After twelve (12) months, if such a well has not been restored to production or use as a service well, the operator shall either: (i) properly plug and abandon the well in accordance with all applicable rules and regulations concerning same; or, (ii) return the well to production operations or use as a service well; or, (iii) file a petition with the Mississippi State Oil and Gas Board, accompanied by a duly executed "Inactive Well Status Report" (Form No. 9-A) requesting that the inactive status of such well be extended for an additional period of time not to exceed twelve (12) months. Any such extension of inactive well status for a well may only be approved by the Board, following notice and hearing, for such additional period as the Board, in its discretion, may deem appropriated but in no event for longer than twelve (12) months. Any petition filed by an operator with the Board to extend a well's inactive status must state the grounds for such extension (e. g., proof of the well's future utility). Any well granted "Inactive Well" status must continue to be reported on Form No. OGB 9-12-15-Z showing the date of last production or the date the well ceased to be used as a service well, together with a notation showing the well is carried on Form No. 9-A, "Inactive Well Status Report" until the well is plugged and abandoned. The extension of Inactive Well status shall not affect the extension or dissolution of the unit as provided in Rule 7 and Rule 8 hereof. b. The "Inactive Well Status Report" shall list the field, well name, well number and other pertinent data and provide an appropriate column to classify such well as having either (1) future utility, or (2) no future utility. If the well is classified as having future utility, the operator shall specify such utility by completing the appropriate column on the form. Wells so classified shall be reviewed periodically by the Supervisor who, at his or her discretion, may require an operator to supply additional information to justify the classification.c. All such wells classified on the "Inactive Well Status Report" (Form No. 9-A) by either the operator or the Supervisor as having no future utility shall be plugged within one hundred twenty (120) days from the date of such classification unless an extension of time is otherwise granted by the Mississippi State Oil and Gas Board, following notice and hearing. d. Notwithstanding anything above to the contrary, all such wells within designated secondary and tertiary recovery projects do not have to be reported on the "Inactive Well Status Report" if the designated secondary or tertiary recovery project is listed on the Form No. OGB 9-12-15-Z beside each inactive well reported therein. 3. Administrative Interpretation For purposes of administering the heretofore mentioned paragraphs, it is understood that:
a. A wellbore which is completed in more than one common source of supply (multiple completions) shall not be considered as ceasing to produce and shall not be reported on the "Inactive Well Status Report" as long as there is production from or operations in any completion in the wellbore. b. Failure to file the "Inactive Well Status Report" and to indicate the date the well was last produced or utilized may subject the well to immediate plugging. c. Any interested party at any time shall have the right to review by the Board upon notice and hearing with respect to the administration of any provision hereof. d. A designated secondary or tertiary recovery project shall be considered to be a fieldwide unit approved by the Board for operation pursuant to Mississippi Code Annotated Section 53-3-101, et seq., and which is currently being operated under Special Field Rules which provide for secondary recovery, pressure maintenance, cycling operations, water flood, tertiary recovery, or any combination thereof. B. Procedure For Plugging Plugging shall be in accordance with the permit issued as provided for in the preceding rule and unless the permit or Form No. 6 sets forth the method and procedure of plugging the well, the following shall be applicable:
1. With reference to the following, mud shall mean a mud fluid or weighted salt water fluid of sufficient weight to offset the hydrostatic pressure of any of the formations penetrated and cement shall mean cement or a proper cement-admix recognized by and of accepted use in industry. 2. All holes in which no casing was run shall be plugged as follows: a. The hole shall be filled with mud, and cement plugs of not less than one hundred (100) feet in length shall be placed to protect each producible pool and a cement plug of not less than one hundred (100) feet must be place approximately fifty (50) feet below all freshwater-bearing strata, together with additional cement plugs to properly protect all uncased freshwater-bearing sands. Further, a cement plug of not less than one hundred (100) feet shall be placed at the bottom of the surface pipe (50 feet in and 50 feet out). A cement plug of at least twenty-five (25) feet shall be placed inside the casing near the surface of the ground, the casing cut off in such a manner so as not to interfere with soil cultivation, and a steel plate welded to the top of the casing stub. b. Such other plugs as are deemed necessary by the Board to properly plug the well. c. Placement of all plugs shall be verified by tagging in a manner acceptable to the Board. In lieu of tagging the placement of plugs, the operator may double the size of the plug set forth in Paragraph (a) above. d. The operator shall notify the Board's representative 48 hours prior to setting the plugs to afford him the opportunity to witness the placement, tagging (if applicable) and testing (if applicable) of all plugs. 3. All wells, excluding those classified as Class II injection wells, in which production casing has been set shall be plugged as follows: a. If the production casing is not to be immediately pulled, a cement plug of not less than one hundred (100) feet or bridging plug with cement on top shall be placed near the bottom of the casing string at a depth equal to at least 0.9 times the top open perforation and in such position as to protect any producible pool. A cement plug of not less than one hundred (100) feet in length shall be placed inside the production casing at approximately fifty (50) feet below all freshwater-bearing strata. A cement plug of at least twenty-five (25) feet shall be placed inside the smallest string of casing and in all annular spaces near the surface of the ground, the casing(s) cut off in such a manner so as not to interfere with soil cultivation, and a steel plate welded to the top of the casing stub(s). b. Where the production casing is to be pulled, a cement plug of not less than one hundred (100) feet or bridge plug with cement on top shall be placed near the bottom of the production string at a depth equal to at least 0.9 times the top open perforation so as to properly protect any producible pool and the hole filled with mud up to the point where the production casing is severed. The hole shall be filled with mud and a cement plug of not less than one hundred (100) feet in length shall be placed at approximately fifty (50) feet below all freshwater-bearing strata, together with additional cement plugs to properly protect all uncased freshwater-bearing sands. Further, if the base of surface casing is exposed by pulling the production casing a cement plug of not less than one hundred (100) feet shall be placed at the bottom of the surface pipe (50 feet in and 50 feet out). A cement plug of at least twenty-five (25) feet shall be placed inside the casing near the surface of the ground, the casing cut off in such a manner so as not to interfere with soil cultivation, and a steel plate welded to the top of the casing stub. c. Such other cement plugs and testing of plugs as is deemed necessary by the Board to properly plug the well. d. The placement, tagging and testing, if any, of all cement plugs shall be witnessed by a representative of the Board. If the option of a bridge plug is chosen for plugging, or if a cement retainer is used for cementing, tagging of the plug will not be required. Also, in lieu of tagging the cement plugs, the operator may double the size of any cement plug set forth in Paragraphs (a) and (b) above. e. The operator shall notify the Board's representative 48 hours prior to setting the plugs to afford him the opportunity to witness the placement, tagging (if applicable) and testing (if applicable) of all plugs. 4. All wells classified as Class II injection wells shall be plugged under the procedure included in Rule 63. 5. After the well is plugged and abandoned and prior to releasing the well to the landowner for unrestricted use, a NORM survey shall be run pursuant to Rule 69 and a Form 21 must be filed with the Board within sixty (60) days after plugging. 6. The operator shall have the option as to the method of placing cement or cement-admix in the hole by (1) dump bailer, (2) pumping through tubing, casing, or drill pipe, (3) pump and plug, or (4) other method approved by the Board. 7. Within thirty (30) days after the plugging of any well, the owner, operator, or producer responsible therefore who plugged, or caused to be plugged, the well shall file an affidavit on Form No. 7 with the Board, setting forth in detail the method used in plugging the well and a record of any casing removed.C. Restoration of Location 1. Whenever a well location is abandoned, for whatever reason (including the plugging of the well), all materials, debris, equipment and machinery, including, but not limited to, drill pipe, casing, tubing, treaters, separators, tanks, concrete bases and all other drilling production, processing, injection, and plant equipment and above-ground pipelines and related facilities, shall be removed from such location, as well as from any associated oil and gas exploration, production, processing and/or storage sites or locations which have likewise been abandoned. All wastes and other materials, including petroleum-contaminated soil, shall be removed from the location and associated sites and disposed of in accordance with appropriate permit(s) or regulation(s); provided, however, that petroleum-contaminated soil may be approved by the Supervisor for ON-SITE REMEDIATION. In conjunction with the restoration and clean-up of such location(s) and associated site(s), all underground or buried lines shall be flushed and capped at both ends. The removal and disposal of all materials, debris, equipment, etc. from such locations and associated sites shall be conducted in compliance with all applicable Statewide Rules and Regulations, including but not limited to Statewide Rule 68 and Statewide Rule 69 relating to NORM-contaminated wastes.2. Any excavations shall be filled and the overall location graded or contoured to prevent erosion.3. All water source wells drilled in connection with the operation shall be properly plugged and abandoned unless future utilization of such well(s) is desired by the landowner, in which event the operator must obtain the written consent of the landowner to leave the water source well(s) open. A copy of such written request by the landowner must be filed with the Supervisor.4. In any event, the location must be restored within ninety (90) days of the date of plugging and/or abandonment in a manner to be approved by the Supervisor. MCA Section 53-1-17(3) (1972)
