Abstract: A method and system for monitoring and controlling an injection operation is disclosed. A plurality of distributed fiber optic sensors is located in a production well. Fluid is injected into an injection well spaced apart from the production well. A parameter of a formation between the production well and the injection well is determined from measurements from the formation obtained using the fiber optic sensors. At least one of an injection of fluid into the injection well and a flow into the production well is controlled in response to the determined parameter.

Abstract: The present disclosure provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools and controlling injection operations based on measurements in an injection well and/or a production well.

Abstract: The present invention provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools. In one system fiber optics sensors are placed in the wellbore to make distributed measurements for determining the fluid parameters including temperature, pressure, fluid flow, fluid constituents and chemical properties. Optical spectrometric sensors are employed for monitoring chemical properties in the wellbore and at the surface for chemical injection systems. Fiber optic sensors are utilized to determine formation properties including resistivity and acoustic properties compensated for temperature effects. Fiber optic sensors are used to monitor the operation and condition of downhole devices including electrical submersible pumps and flow control devices. In one embodiment, a common fluid line is used to monitor downhole parameters and to operate hydraulically-operated devices.
