Method of Estimating Well Disposal Capacity

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 the waste injection based on the calculated injection volume, and outputting at least one of the disposal volume and the time interval is disclosed.

Method of Using Pressure Signatures to Predict Injection Well Anomalies

A method of desiging a response to a fracture behavior of a formation during re-injection of cuttings into a formation, the method including obtaining a pressure signature for a time period, interpreting the pressure signature for the time perios to determine a fracture behavior of the formation, determining a solution based on the fracture behavior of the formation, and implememting a solution is disclosed.
