TO BE RESCINDED

 

3745-9-06                    Casing for new wells.

 

 

 

(A)   Casing and liner pipe for new wells shall be sufficiently sturdy to resist the forces imposed upon the casing and liner pipe during installation and those forces and conditions which can normally be expected after installation.

 

(B)  The thickness of steel used for casing and liner pipe for new wells shall be selected in accordance with good design practice as applied to conditions encountered in the area where the new well is located. In no event shall steel casing thicknesses and weights be less than as shown in the following table:

Casing Suitable for Driving Where Conditions Are Favorable (Known as Water Well Casing)

Nominal Size in Inches	Outside Diameter in Inches	Wall Thickness in Inches	Weight of Plain End Casing in lbs/ft
3.500	3.500	0.125	4.51
4.000	4.00	0.134	5.53
4.500	4.50	0.142	6.61

8.625	8.625	0.188	16.94

Casing of a nominal size not listed in the above table shall have a thickness not less than that required for the next smaller nominal size listed.

(C)   Materials other than steel may be used as casing or liner pipe for new wells only if a waiver has been obtained from the director under 3745-41-02 and 3745-41-03.

(D)   Defective or visibly damaged pipe shall not be used as casing or liner pipe for new wells. Pipe withdrawn from another well or test hole may be used as casing or liner pipe for new wells provided such pipe meets the requirement of the preceding sentence and all other requirements set forth in this regulation, 3745-9-06. Pipe that has become impregnated with any contaminant, including but not limited to natural gas and crude oil, during a previous use shall not be used as casing or liner pipe for new wells.

(E)    Casing for new wells that is of riveted construction shall have all seams and rivets welded in order to insure water tightness.
