1. A computer-implemented method for determining locations of wells in a field with subsoil containing a hydrocarbon reservoir, the method comprising:
/a/ receiving a plurality of geological gridded models, each gridded model among the plurality of geological gridded models including a respective plurality of cells;
/b/ receiving a set of criteria for positioning wells in a geological gridded model;
/c/ receiving a plurality of reference well patterns, each reference well pattern among the plurality of reference well patterns including a respective plurality of reference locations of wells in a respective geological gridded model among the plurality of geological gridded models;
/d/ for each geological gridded model among the plurality of geological gridded models:
/d1/ for a number of iterations equal to a number of wells in the reference well pattern respectively associated to the geological gridded model:
determining a group of cells among the respective plurality of cells of said geological gridded model;
for each cell among said group of cells, computing criterion measures, each criterion measure representing a suitability to a respective criterion among the received set of criteria;
determining, based on said criterion measures, a set of non-dominated cells among said group of cells via a non-dominated sorting algorithm for jointly optimizing the set of criteria;
determining a first cell among the set of non-dominated cells, said first cell minimizing a distance between the plurality of reference locations of the reference well pattern respectively associated to the geological gridded model and the set of non-dominated cells; and
determining a plurality of intermediate weights based on coordinates of the first cell in a space defined by the set of criterion measures, each intermediate weight being associated to a respective criterion among the set of criteria;
/e/ estimating a plurality of weights, each weight being associated to a respective criterion among the set of criteria and estimated based on intermediate weights among the plurality of intermediate weights associated to said respective criterion;
/f/ receiving a second geological gridded model of the field, said second geological gridded model including a respective plurality of cells;
/g/ determining locations of wells in the second geological gridded model based on the received set of criteria and the plurality of estimated weights; and
/h/ based on the determined locations, injecting one or more fluids into the subsoil or producing fluids from the field in the subsoil.
