  • SENSOR AND ACTUATOR FOR AUTONOMOUSLY DETECTING RESISTIVITY DERIVATIVES OF WELLBORE FLUIDS AND CLOSING FLUID PATH
    Publication number: 20240035370
    Abstract: A sensor device can be used to detect the presence of a cement composition in a reverse cementing operation. The sensor device can include a resistivity sensor, an acquisition and measurement apparatus, and an actuator. The actual derivative of resistivity of the drilling mud, spacer fluid, and cement composition to be used can be pre-determined. The acquisition and measurement apparatus can be pre-programmed with a slope change derivative of resistivity profile for the fluids. The resistivity sensor can measure the resistivity of the fluids as they flow past the resistivity sensor in the wellbore. When the acquisition and measurement apparatus receives a desired slope change reading within the slope change derivative of resistivity profile, instructions can be sent to the actuator to close a valve and block fluid flow through the casing or tubing string.
