Minimum Surface Casing Requirements--Appendix B


Eastern Surface Casing Order #133,891-C

Area 1: (See exhibit.)

Oil, gas or injection wells drilled in Area 1 shall be completed under Alternate II rules only. A bond log may be required on the long string from the operator by the Kansas Corporation Commission.

The following rules shall apply:

  1. Set a minimum of 20 feet of steel surface pipe or to the depth of the first solid formation capable of supporting the surface pipe, whichever is greater. Also, set through all unconsolidated alluvial sediments and a minimum of 5 feet into the top of the underlying formation capable of supporting the surface pipe.
  2. No well shall be drilled closer than 660 feet of an existing domestic or municipal water well without written owner notification, a copy of which must be attached to the drilling intent form during filing. Special casing and cementing requirements may be imposed in those areas producing fresh and usable water.
  3. If a well is completed, the production or long string casing nearest the formation wall shall be cemented from bottom to top.
  4. The surface casing borehole shall be at least (2 1/4) inches greater than the surface casing outside diameter. The well bore below the surface casing shall be at least (2 1/4) inches greater than the outside diameter of production or long string casing. The inside diameter of surface casing shall be at least (2 1/4) inches greater than the outside diameter of the production or long string casing.
  5. All wells shall be completed Alternate II or plugged within 30 days of the spud date. An extension may be granted by the District Supervisor of the Conservation Division upon written request by the operator. The responsibility for plugging or completing the well is referenced in K.S.A. 55-172.
  6. If the well is dry and no long string or production pipe has been cemented in place, the well shall be plugged in the following manner:
    Arbuckle: Plug all oil and gas producing zones or formations containing fresh or usable water and plug for 50 feet above the Arbuckle.
    Mississippi: Plug all oil and gas producing zones and formations containing fresh or usable water and plug for 50 feet above the Mississippian.
    Pennsylvanian: Plug for 50 feet above all oil, gas, and uppermost saltwater zones and plug from 50 feet below Table I to surface. Intervals between plugs shall be filled with drilling mud.

Area 2:

Oil, gas or injection Wells drilled in Area 2 shall be completed under Alternate II rules only. A bond log may be required on the long string from the operator by the Kansas Corporation Commission. The following rules shall apply:

  1. Set a minimum of 20 feet of steel surface pipe or to the depth of the first solid formation capable of supporting the surface pipe, whichever is greater. Also, set through all unconsolidated alluvial and glacial drift sediments and a minimum of 5 feet into the top of the underlying formation capable of supporting the surface pipe.
  2. No well shall be drilled closer than 660 feet of an existing domestic or municipal water well without written owner notification, a copy of which must be attached to the drilling intent form during filing. Special casing and cementing requirements may be imposed in those areas producing fresh and usable water.
  3. If a well is completed, the production or long string casing nearest the formation wall shall be cemented from bottom to top.
  4. The surface casing borehole shall be at least (2 1/4) inches greater than the surface casing outside diameter. The well bore below the surface casing shall be at least (2 1/4) inches greater than the outside diameter of production or long string casing. The inside diameter of surface casing shall be at least (2 1/4) inches greater than the outside diameter of the production or long string casing.
  5. All wells shall be completed Alternate II or plugged within 30 days of the spud date. An extension may be granted by the District Supervisor of the Conservation Division upon written request by the operator. The responsibility for plugging or completing the well is referenced in K.S.A. 55-172.
  6. If the well is dry and no long string or production pipe has been cemented in place, the well shall be plugged in the following manner:
    Arbuckle: Plug all oil and gas producing zones or formations containing fresh or usable water and plug for 50 feet above the Arbuckle.
    Mississippi: Plug all oil and gas producing zones and formations containing fresh or usable water and plug for 50 feet above the Mississippian.
    Pennsylvanian: Plug for 50 feet above all oil, gas, and uppermost saltwater zones and plug from 50 feet below Table I to surface. Intervals between plugs shall be filled with drilling mud.

Area 3:

Wells drilled in Area 3 can be completed under Alternate I or Alternate II rules, the operator using Alternate I rules will set surface pipe for the protection of fresh and usable water as specified in Table I and will cement production or long string casing not less than 150 feet above the upper oil and gas zone to be tested or produced.

Alternate II rules for Area 3 are as follows:

  1. Set minimum of 40 feet of steel surface pipe or to the depth of the first solid formation capable of supporting the surface pipe, whichever is greater. In designated areas, operators shall set through all surface or near surface sandstone aquifers and a minimum of 5 feet into the underlying formation. Also, set through all alluvial and glacial drift sediments and a minimum of 5 feet into the top of the underlying formation capable of supporting the surface pipe.
  2. No well shall be drilled closer than 660 feet of an existing domestic or municipal water well without written owner notification, a copy of which must be attached to the drilling intent form during filing. Special casing and cementing requirements may be imposed in those areas.
  3. If a well is completed, the production or long string casing nearest the formation wall shall be cemented from bottom to top.
  4. The surface casing borehole shall be at least (2 1/4) inches greater than the surface casing outside diameter. The well bore below the surface casing shall be at least (2 1/4) inches greater than the outside diameter of production or long string casing. The inside diameter of surface casing shall be at least (2 1/4) inches greater than the outside diameter of the production or long string casing.
  5. All wells shall be completed or plugged within thirty (30) days of the spud date. An extension may be granted by the District Supervisor of the Conservation Division upon written request by the operator. The responsibility for plugging or completing the well is referenced in K.S.A. 55-172.
  6. If the well is dry and no long string or production casing has been cemented into place, the well shall be plugged in the following manner:
    Arbuckle: Plug all oil and gas producing zones with cement and plug for 50 feet above the Arbuckle.
    Simpson-Viola and Hunton: Plug any oil and gas producing zones with cement and at top of upper formation for 50 feet.
    Mississippi: Plug with cement all oil and gas producing zones and for 50 feet above the top of the Mississippian.
    Pennsylvanian: Plug for 50 feet above all oil, gas, and uppermost saltwater zones and plug from 50 feet below Table I to surface. Intervals between plugs shall be filled with drilling mud.
