ARSD 74:55:01:34. Determining information on water-bearing injection zone

The following information concerning the water-bearing injection zone shall be determined: (1) Fluid pressure; (2) Temperature; (3) Fracture pressure; (4) Other physical and chemical characteristics of the injection zone rock and formation fluids including: geochemistry of the production zone and the aquifer up-gradient and down-gradient of the production zone, to include oxidation-reduction conditions and common ions, and the direction and velocity of ground water movement through the producing zone; and (5) Compatibility of injected fluids with formation fluids.
