Abstract
System and method for predicting the mud weight window in formations, particularly those formations having geologic structures such as salt domes. One embodiment is a computer-implemented method of modeling a formation in 3-D and determining a plurality of effective stress ratios for the modeled 3-D formation using finite element analysis. Thereafter, the trajectory of a proposed wellbore through the 3-D modeled formation is plotted and the specific effective stress ratios along the wellbore are selected to form a data set. The 3-D data set of effective stress ratios is then imported into 1-D modeling software and combined with 1-D data. The combined data is thereafter utilized to estimate the mud weight window for the formation around the wellbore.
