Claim Text:
1. A method of constructing with a programmed computer a grid representative of a distribution of a physical property of an underground formation by multipoint statistical simulation, from at least one conditioning point where a value of the property is known and each cell of the grid is associated with a geographical position, comprising: a) defining a set of initial cells containing at least one of the conditioning points; b) visiting each initial cell of the set of initial cells and assigning to each cell a value representative of the property using a filling method constrained by at least one of the conditioning points; c) identifying at least one unvisited cell adjacent to at least one already visited cell and determining a number of adjacent visited cells for each unvisited cell; d) visiting each unvisited cell according to a decreasing order of a value of the number and assigning to each unvisited cell a value representative of the property using a filling method constrained by at least one adjacent visited cell; e) repeating c) to d) until each cell of the grid has been visited; and f) using the grid to develop the underground formation.
