Claim 13:
14. The lube oil system of claim 9, wherein the control system comprises:
a control valve installed on the intermediate flowline; and
a controller communicatively coupled to the level sensor and to the control valve, wherein the controller is configured to compare the liquid level in the cylinder lubricator oil reservoir measured by the level sensor with a specified low liquid level, and the controller is configured to transmit an open signal to the control valve to open the control valve in response to determining that the liquid level in the cylinder lubricator oil reservoir measured by the level sensor is less than or equal to the specified low liquid level, thereby allowing the first lube oil from the tubing network to flow through the intermediate flowline and into the cylinder lubricator oil reservoir via the control valve that has opened.
