Abstract:
A method of exploring a heterogeneous geological original reservoir by means of a transposed reservoir equivalent to the original reservoir with respect to a determined type of physical transfer function known for the original reservoir, said method comprising the steps of:(a) analyzing the original reservoir to acquire data as to physical characteristics of the original reservoir,(b) forming a two-dimensional image of the original reservoir as a array of pixels, based on the acquired data;(c) associating with each pixel of the array an initial value for the physical transfer function,(d) assigning a value for the physical transfer function at each pixel of said array, by reference to values of the function assigned to neighboring pixels of the image;(e) determining a physical property of the transposed or equivalent reservoir by identifying a volume portion of the equivalent reservoir based on the physical transfer function for the corresponding volume portion of the original reservoir; and(f) physically exploring the original reservoir based on the determined physical property.
