System and method for determining production from a plurality of wells

Abstract

A method includes receiving field measurement data of a plurality of well-pumps disposed respectively in a plurality of wells. The field measurement data are representative of speed data and run-time data of the plurality of well-pumps. The method further includes receiving commingled-flow measurement data. The commingled-flow measurement data are representative of a combined fluid flow data of the plurality of wells. The method further includes determining, by an optimizer unit, well-flow data of the plurality of wells based on the commingled-flow measurement data, the field measurement data, and a plurality of conservation constraints generated by a constraint generator. The well-flow data are representative of fluid flow data from each of the plurality of wells. The method also includes controlling operation of at least one of the plurality of well-pumps based on the well-flow data to control fluid production from the plurality of wells.

Description

BACKGROUND[0001]Embodiments of the present invention relate generally to production in an oil field, and more particularly to a system and a method for determining fluid flow estimates of individual wells based on a measurement of commingled flow at a pool-line.[0002]Produced fluid from wells may include various quantities of crude oil, natural gas and / or water, depending on the specific conditions of reservoir. The amount and rate at which fluid is extracted from a well depends on condition of the reservoir such as a pressure difference between the reservoir and a wellbore. The wellbore pressure may be adjusted by various devices such as pumps, compressors, fluid injection devices the like.[0003]Various devices may be used to separate oil and water from gas in the produced fluid. The surface devices are designed to process selected volume or quantity of the produced fluid. The selected volume depends on volumes of production from various wellbores and number of wellbores coupled to...

Problems solved by technology

However, such simulations may not provide feasible solutions for specified production constraints.

Another issue is that the feasible solutions provided by the simulations may not be practical for implementation.
