Identification & understanding of the FEM models used to simulate casings in oil wells

There are many complex problems in the field of Engineering Design, the mathematical solution of which is tedious and complex, and usually not possible by analytical methods. In such cases we route to the use of numerical techniques. Here lies the importance of Finite Element Method (FEM), a very strong tool for obtaining the numerical solution of a wide range of engineering problems. The basic concept of FEM is that a body or structure is divided into smaller elements of finite dimensions called "Finite Elements", connected to one another by nodes or nodal points. The properties of the elements are formulated and combined to obtain the properties of the entire body.;In the initial phase we will discuss the FEM analysis for determining the state of stresses around bore holes. While in the final phase casing design and the interaction between the well casings and liners with the borehole will be studied. In the end there will be a brief summary and conclusions.;The purpose of this project is to identify, study and understand the FEM models used to simulate oil well casings. We will discuss the transmission of loads through porous media to the well component, including the pore pressure and stresses inside the rock or on oil wells before and after the drilling.
