Abstract
Systems and methods for injection fluid into a well or aquifer while regulating pressure. The systems and methods include a back pressure valve biased to a closed position. The back pressure opens when an injection pressure of the fluid exceeds a reference pressure. The back pressure valve controls pressure of the injection fluid above the back pressure valve to maintain the injection fluid in a dense state.
