Systems and methods for determining a pump flow (Q) of a pump are disclosed. A method for determining a pump flow (Q) of a pump includes calculating an inverse of a polynomial equation defining a DP-Q performance curve of a pump, where the inverse is a Q-DP polynomial equation defining the performance of the pump, receiving a pump head (DP) value from a pump head sensor associated with the pump, computing a pump flow based on the Q-DP polynomial equation, comparing the computed pump flow to a preset target flow rate, and automatically controlling a pump parameter of the pump such that the calculated flow rate becomes the preset target flow rate.

Methods for controlling pump flow rate based on pump flow rate estimation using pump head and performance curves and pump control systems having the same

In a hydrocarbon field including multiple production wells and injection wells, at a hydrocarbon field level, a long-term field-level target and optional long-term well-level targets for the field are received by a field-level processor. The long-term field-level target including a long-term field-level production target indicating a quantity of hydrocarbons to be produced and a long-term field-level injection target indicating a quantity of fluid to be injected into the field. The field-level processor determines short-term individual production targets for the production wells and short-term individual injection targets for the injection wells to achieve the long-term field-level target. At an individual well level, individual hydrocarbon productions of the production wells or individual fluid injections of the injection wells are controlled, by at least one individual well-level processor independent of the field-level processor, to achieve the long-term field-level target.
