MAXIMUM INJECTION RATE ALTERNATE AOR METHOD
STATIC FLUID LEVEL MEASUREMENT
Use of Static Fluid Level Measurement as alternate compliance method with 62 IAC Section 240.360.
Specifically 62 IAC Section 240.360, requires the applicant to submit evidence for all wells which penetrate the injection
formation within the AOR and which are determined by the Department to contain an inadequate amount of cement or are
inadequately constructed or plugged, that injection into the proposed well and formation will not cause contamination of the
freshwater zone. If well fluid level measurements are required as part of the submitted evidence, the fluid level measurements
shall be witnessed by a Department Well Inspector.
The following DEFAULT values will be utilized in calculating the allowable Maximum Injection Rate (B/D) unless the applicant
proposes alternate values. Supporting documentation for proposed values must be provided and will be subject to review by the
Department.

Injection Fluid Viscosity: Viscosity of fluid is a function of temperature, salinity, and pressure. As temperature decreases, viscosity
increases. As salinity and/or pressure increases so does the viscosity.
Formation Volume Factor: Produced water formation volume factor (FVF), B
, is defined as the volume at reservoir conditions
w
occupied by 1 stock tank barrel (STB) of formation water plus its dissolved gas.
Permeability of the injection interval (each injection interval by formation).
Compressibility is the total compressibility of the formation and fluid.
Porosity: The measured average porosity within the injection interval expressed as a percent (each injection interval by formation).
Time: Evaluates the effect of injection at a specified time after the initial injection.
