1. A method of monitoring and controlling an injection operation, comprising:

  • locating in a production well a plurality of distributed fiber optic sensors;

    injecting a fluid in an injection well formed spaced apart from the production well;

    determining a parameter of the formation between the production well and the injection well from a measurement of an acoustic signal generated in the formation obtained using the fiber optic sensors; and

    controlling a flow of fluid into the production well in response to the parameter determined from the measurement of the acoustic signal generated in the formation.
