36.22.1415 RECORDS REQUIRED
(1) The owner or operator of any Class II injection well or wells must keep and retain for at least five years, an accurate record of :
(a) the cumulative amount of fluid injected into such well or wells;
(b) the wellhead pressure or pressures, and the injection rate at the time the pressure is recorded;
(c) the total amount of water produced, and the total amount of oil and gas produced from an enhanced recovery project;
(d) the pressure in the casing-tubing annulus, if monitoring of such pressure is required as part of a mechanical integrity test;
(e) the results of any chemical or physical analyses performed on injection zone fluids and injected fluids.
(2) The information required in subsections (1)(a) through (d) of this rule must be observed at least weekly and a representative observation recorded at least monthly and filed with the board on board Form 5.
(3) The owner or operator of any Class II injection well permitted after the effective date of this rule must conduct a chemical analysis of the typical injected fluids during the twelfth month of injection. Samples of typical injected fluids must be taken at the injection wellhead, or, where more than one well is receiving fluid from a common facility, the sample may be taken from the discharge line of such facility. The chemical analysis of the typical injected fluids must include tests for total dissolved solids (TDS), specific conductivity, pH, and percent oil and grease. The results of such analysis must be submitted in writing to the board within 45 days after the sample is taken.
