OG exemplary drawing
 
1. A process control system for use in an oil and/or gas production, transportation and/or storage system, comprising:
a controller configured to receive an input signal comprising measurement data relating to a production fluid flow in an oil and/or gas production, transportation and/or storage system,
the controller configured to determine from the received input signal an adjustment in the configuration of a flow control arrangement of the production wellbore,
wherein the controller is configured to provide an output signal indicative of the adjustment in the configuration of the flow control arrangement,
and wherein the system comprises, is coupled to, or operatively associated with a choke valve.
 
29. A process control system for use in an oil and/or gas production, transportation and/or storage system,
wherein the process control system comprises, is coupled to, or is operatively associated with a flow control arrangement of a production wellbore of the oil and/or gas production, transportation and/or storage system, the process control system configured to mitigate at least one of the formation of gas hydrates and/or the accumulation of paraffin wax, asphaltenes or other solids in the oil and/or gas production, transportation and/or storage system by providing an output signal indicative of an adjustment in the configuration of the flow control arrangement so as to vary the injection of a chemical into the production, transportation and/or storage system, and,
wherein the process control system comprises, is coupled to, or operatively associated with a choke valve and a chemical injection metering valve of the flow control arrangement, and comprises:
a controller configured to:
receive an input signal comprising measurement data relating to a production fluid flow in the oil and/or gas production, transportation and/or storage system;
determine from the received input signal an adjustment in the configuration of the flow control arrangement,
wherein the controller is configured to determine the adjustment in the configuration of the flow control arrangement using an artificial intelligence algorithm; and
provide the output signal indicative of the adjustment in the configuration of the flow control arrangement,
wherein the output signal indicative of the adjustment in the configuration of the flow control arrangement comprises chemical metering data to be fed to the chemical injection metering valve of the flow control arrangement, and
wherein the output signal indicative of the adjustment in the configuration of the flow control arrangement comprises choke control data to be fed to an actuator arrangement configured to control the choke valve.
