Integrated 3D method for prediction of mud weight window for complex well sections

Xinpu Shen, Halliburton


This work introduces an integrated 3D method for prediction of the mud-weight window (MWW) for complex well sections. The numerical results for all three principal stress components obtained by the 3D finite-element method are introduced into a 1D analytical tool as input data, and thus no need to use the submodel method to obtain the MWW curve for the full length of the well trajectory. The integrated 3D method has a higher accuracy than the conventional 1-D method, and much lower computational costs than the direct 3-D method. Illustrative validation examples are introduced, and a brief comparison of the MWW solution obtained with these three types of calculation methods are presented.
