Claim 10:
11. The lube oil system of claim 10, wherein:
the control system comprises an inlet valve coupled to the cylinder lubricator oil reservoir and to the intermediate flowline;
the float controller is communicatively coupled to the inlet valve;
the float 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;
the float controller is configured to open the inlet 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 through the inlet valve that has opened.
