Abstract
The present disclosure relates to methods and systems for controlled delivery of unknown fluids that safely and efficiently removes entrained gas from unknown fluids in the wellbore and/or marine riser. A control system automatically controls one or more choke manifold(s), and optionally the flow rate of one or more mud pump(s), to maximize the safe flow rate of returning unknown fluids to one or more instrumented mud-gas separator(s) without overloading. The control system may receive the state of the one or more instrumented mud-gas separator(s) to manipulate the choke manifold(s), and optionally the one or more mud pump(s) to maximize the safe flow rate of return fluids and expedite the removal of gases.
Claims35
A drilling system for controlled delivery of unknown fluids comprising:
- a blowout preventer comprising a wellbore fluid return line that directs unknown wellbore fluids to a choke manifold;
- an instrumented mud-gas separator that receives unknown wellbore fluids from the choke manifold, the instrumented mud-gas separator comprising a sensor that outputs a sensor signal indicative of a state of the instrumented mud-gas separator;
- and
- a control system that controls a state of the choke manifold that directs unknown wellbore fluids to the instrumented mud-gas separator based on the sensor signal to maximize a flow rate of the unknown wellbore fluids to the instrumented mud-gas separator while maintaining the instrumented mud-gas separator in an operational state.
A method of controlled delivery of unknown fluids comprising:
- receiving, by a control system, a sensor signal from an instrumented mud-gas separator, wherein the sensor signal is indicative of a state of the instrumented mud-gas separator;
- and
- controlling a state of a choke manifold that directs unknown fluids to the instrumented mud-gas separator based on the sensor signal to maximize the flow rate of the unknown fluids to the instrumented mud-gas separator while maintaining the instrumented mud-gas separator in an operational state.
