| 主权项 | 1. A pump for pumping hydraulic well control fluid expelled from a control device of a well, the pump comprising: a cylinder arrangement configured to accumulate the expelled hydraulic well control fluid; a mechanism configured to use the pressure of hydraulic fluid supplied to the well to pump accumulated expelled hydraulic well control fluid into a production flowline of the well and a sensor configured to sense a pressure of accumulated expelled hydraulic well control fluid to produce an indication for use in increasing a pressure of hydraulic fluid at the second inlet in response to the pressure of accumulated expelled hydraulic well control fluid reaching a predetermined value. | ||
