Drilling and Completion in Petroleum Engineering: Theory and Numerical Applications

Multiphysics modeling has been widely applied in the petroleum industry since the 1970s. The rapid development of computer technology has enabled the numerical applications of multiphysics modeling in the petroleum industry: its applications are particularly popular for the numerical simulation of drilling and completion processes. This book introduces the following contents of theory and numerical applications of multiphysical modeling: 1. Mathematical modeling of thermo-hydro-mechanical behavior for a porous continuum under elevated temperature and its finite element formulation 2. 3D numerical simulation of drilling processes and the design of a safe mud weight window 3. Stress orientation analysis related to pressure depletion and production enhancement measures 4. Numerical prediction of sanding production and measurement for sanding control 5. Numerical simulation of hydraulic fracturing and estimates of production enhancement measures 6. Wellbore trajectory optimization: criteria and numerical scheme 7. Introduction of integrated analysis that combines 2D analytical tools and 3D numerical software; advantages of 3D solutions and 2D analytical solutions have been combined synthetically to ensure the efficiency and accuracy of the solution 8. Concepts and numerical analysis of naturally fractured reservoirs This book can be used as a manual of typical examples and modeling skills for numerical engineers in petroleum engineering; it includes numerical examples from drilling and completion practice, as well as an introduction of key numerical modeling skills. This book can also be used as a course reference book by graduate students majoring in solid mechanics and/or numerical methods in petroleum engineering, as well as for geotechnical engineers.
