Minimum Surface Casing Requirements
Minimum surface casing requirements for protecting fresh and usable water and to meet alternate #1 on Intent to Drill cards, Form C-1
S=Section, T=Township, R=Range
Wells deeper than 1500 feet and using Alternate I completion shall set a minimum surface casing of 300 feet or through the Kansas City Group plus within one mile of the nearest Kansas River Valley wall surface casing must reach below 700 feet elevation mean sea level in T.12 and 13S-R.21E; 690 feet m.s.l. in T.12S-R.22E; 670 feet m.s.l. in T.12S-R.23E; and 660 feet m.s.l. in T.12S-R.24E. All other wells shall follow Alternate II rules, Appendix B, Area 2, Eastern Surface Casing order. In all cases, set surface casing through all unconsolidated material plus 20 or more feet into the underlying formation.
For areas in which casing settings are given as sea level datums, topographic maps are available showing surface elevations. These maps may be obtained from the U.S. Geological Survey at Denver, Colorado; Rolla, Missouri and Washington, D.C.; and the State Geological Survey, Lawrence, Kansas.
