The invention stimulates production of an oil reservoir by determining a flow simulator from physical data measured in the oil reservoir; determining a first analytical model relating the production of the reservoir as a function of time by accounting for parameters which provides adjustment to production values closest to the production of the reservoir, the first model providing adjustment to the production values closest to a production values provided from the flow simulator; selecting at least one new production value, which is obtained from the reservoir simulator; and determining a second model by adjusting the first model so that the second model interpolates the new production value.

Method of modelling the production of an oil reservoir

The method of the invention is applicable to oil production to obtain the impact of technical and economic uncertainties on the economic profitability of a reservoir and/or to optimize the position of a new well in order to meet a development strategy. The invention includes in stage 1, uncertain technical parameters having an influence on the reservoir production are selected; in stage 2, an analytic model expressing the reservoir production in the course of time is determined as a function of the parameters selected in stage 1, from production values obtained by means of a flow simulator; and in stage 3, a model expressing the economic profitability of the reservoir is determined as a function of the technical and economic parameters, from the analytic model determined in stage 2.

Decision support method for oil reservoir management in the presence of uncertain technical and economic parameters

A method for optimizing the production of oil reservoirs, and notably the production schemes, while taking into account uncertainties inherent in any reservoir survey. The method sequentially has the following stages:
