Abstract
The lubrication flowmeter is configured to be a part of the lubrication system to grease frack valves. The system generally utilizes a manifold to connect to the various fracked valves and at least one pressure transducer providing wellbore pressure and preferably a second pressure transducer providing grease pressure at either the manifold or the pump. A programmable logic controller is provided to activate the grease pump upon reaching preset conditions and to deactivate the grease pump upon reaching a second set of conditions such as pressure threshold, time limit, or volume limits of greased pumped.
Claims2
1) A lubrication flow meter system comprising:
- a pump,
- a pressure sensor providing an electronic wellbore pressure indication,
- wherein the pump provides lubricant at greater than wellbore pressure,
- a frack valve having a through bore, a grease cavity, and a port between an exterior of the frack valve the grease cavity;
- a programmable logic controller that switches on the pump at predetermined pressure or time intervals,
- wherein the programmable logic controller switches off the pump upon reaching predetermined pressure, time, or volume limits.
