Claim 0:
1. A method comprising:
obtaining, by a computer processor, total stresses and pore pressures of each porous medium of a formation using an N-porosity and N-permeability poroelastic wellbore solution;
determining, by the computer processor, a first set of effective stresses for each porous medium and a second set of effective stresses for the formation;
determining, by the computer processor, an individual collapse mud weight and an individual fracturing mud weight for each porous medium of the formation using a first set of associated failure criteria, wherein the first set of associated failure criteria are based on the first set of effective stresses;
determining, by the computer processor, an overall collapse mud weight and an overall fracturing mud weight for the formation using a second set of associated failure criteria, wherein the second set of associated failure criteria is based on the second set of effective stresses;
determining, by the computer processor, a mud weight window for the formation using the individual collapse mud weight, the individual fracturing mud weight, the overall collapse mud weight, and the overall fracturing mud weight; and
transmitting, by the computer processor, a command to a drilling system based on the mud weight window.
