Abstract:
A method for pressurizing a hydraulic accumulator includes creating an annulus pressure zone in hydraulic communication with the hydraulic accumulator through a hydraulic recharging circuit and applying a hydraulic pressure to the annulus pressure zone. Operating the hydraulic recharging circuit in response to applying the hydraulic pressure and pressurizing the hydraulic accumulator in response to operating the hydraulic recharging circuit.
