Patent ID: 7430501

Claim:
A method for conducting development of a hydrocarbon reservoir modelled by a flow simulator, by taking account of economic implications of uncertain economic parameters and uncertain technical parameters associated with an uncertain domain that influence a production of the reservoir, the flow simulator being constructed from known physical data as a function of the technical parameters, comprising the steps: a) selecting a number of the uncertain technical parameters involved in the flow simulator; b) determining a first analytic model relating the production of the reservoir as a function of time, by taking account of the uncertain technical parameters selected in step a) and matching a finite number of production values obtained by means of the flow simulator; c) from the first analytic model determined in step b), determining a second analytic model as a function of the uncertain technical parameters determined in step a) and of selected economic implications of the uncertain economic parameters, wherefrom an evaluation of a decision support criterion determined by taking account of production uncertainties linked with the selected economic implications of the uncertain economic parameters and the uncertain technical parameters is deduced; and d) modifying development conditions of the hydrocarbon reservoir based on an evaluation obtained for the decision support criterion.
