SELECTING AND OPTIMIZING OIL FIELD CONTROLS FOR PRODUCTION PLATEAU

摘要

A system, method and a computer program product for to determining energy production controls for a given subterranean hydrocarbon (oil) field production and more particularly to specifying controls for sustaining optimal field production (by means of a plateau-like profile over time).

1. A method of selecting and optimizing oil field controls for production plateau comprising:
determining a reservoir model from a description of a reservoir, at least one parameter in said description having an uncertain value and being a source of uncertainty in modeling said reservoir; providing numerical tools adapted to generate a development plan comprising a facilities model and the controls for a predetermined production rate, said development plan comprising:
a distribution of production well locations and optionally injection well locations for the reservoir model,a drilling schedule, anda control of the wells; providing numerical tools adapted to simulate said reservoir model under said development plan conditions for the predetermined production rate adapted to generate an average production profile and the plateau duration and to quantify an associated uncertainty responsive to reservoir description uncertainties, wherein the selection of the controls for production plateau comprises iteratively:
providing an initial value for the production rate variable,providing a cost function that evaluates an average ranking measure, according to the production rate variable, and while the average ranking measure is not maximum:
simulating the reservoir model for the production rate value providing the facilities model and the average ranking measure, andif the average ranking measure is not maximum generating a new production rate, andproviding the field controls according to the production rate that makes the average ranking measure maximum at said associated uncertainty.
