1. An injection system, comprising:
a plurality of injection valves arranged at different injection locations in an injection well in a subterranean formation, each injection valve configured for controlling a flow of carbon dioxide and a corresponding pressure drop through the valve and injecting some of the flow into the subterranean formation;
one or more sensors to sense pressure and temperature of the flow leading to each injection valve; and
a controller in communication with the injection valves and configured having control logic to determine a phase of the carbon dioxide based on the pressure and temperature leading to the respective injection valves and to dynamically adjust the flow at each injection valve based on the phase as determined by the controller to maintain at least a threshold density of the carbon dioxide injected at each injection location.
