A recently granted patent (Publication Number: US11891880B1) outlines a method for preventing flaring at a facility by utilizing pressure measurements from a downstream sensor. The method involves comparing these measurements to a threshold pressure to mitigate flaring events. If the pressure exceeds the threshold, the system analyzes injection response curves for multiple wells to identify the optimal well for adjusting back pressure on the reservoir. An instruction is then transmitted to the selected well to modify the back pressure, with options to increase it through choke valves or by reducing injection flow rates.

Furthermore, the patent includes provisions for determining multiphase inflow performance relationships and vertical lift performance curves for each well, aiding in the calculation of injection response curves. The threshold pressure for preventing flaring is set at approximately 160 psi. The patent also covers a non-transitory computer-readable medium with instructions for executing the method and a system comprising a facility, downstream sensor, and server. The server is equipped to receive pressure measurements, compare them to the threshold, analyze injection response curves, and transmit instructions for adjusting back pressure on the reservoir, with additional capabilities for increasing back pressure through choke valves or flow rate reduction at the selected well.
