Abstract
A method for determining a maximum volume of drilling cuttings disposal in a formation, the method including inputting formation parameters into a simulator, simulating a formation during waste injection based on the formation parameters, determining a net pressure based on the simulating, determining a closure pressure increase based on the simulating, calculating a disposal volume based on the net pressure and the closure pressure, calculating a time interval of waste injection based on the calculated injection volume, and outputting at least one of the disposal volume and the time interval is disclosed. A method of optimizing a waste injection process, the method including simulating a formation based on input parameters, determining a closure pressure increase per unit slurry volume based on the simulation, calculating a disposal capacity of the selected formation, and outputting the disposal capacity is also disclosed.
