CALIBRATED MODELING OF PRESSURE PROPAGATION IN THE ARBUCKLE GROUP FROM SALTWATER DISPOSAL IN OKLAHOMA
Utilizing MODFLOW, a groundwater flow model will be designed to have boundary conditions within the sub-regional area with instrumented wells. Input parameters for the model include reservoir properties and hydraulic parameters (transmissivity, storage coefficient, permeability) calculated through solid Earth tide analysis from the collected pressure data and core characterization. The model will simulate pressure within the Arbuckle Group before injection (steady-state conditions) and after the effects of injection (transient conditions).
Scientific models calibrated and verified against observed data are more accurate and useful. Previous attempts to quantify the influence of SWD injection on pressure within the Arbuckle Group by modeling lacked real-time data. Once simulations have been run, the model will be calibrated against the pressure data collected from the instrumented SWD wells. This model can be used as a tool for decision-making regarding SWD in Oklahoma.
