A GLOBAL INTEGRATED MODEL FOR A TIME-DEPENDENT WELLBORE STABILITY PREDICTION
Mostafa Magdy Elsayed AbdelHafiz;
Abstract
Key Words:
Wellbore stability; Mechanical Earth Model; Rock Mechanics;Safe Mud window; Optimum well trajectory
Summary
This work presents an integrated wellbore stability model using well log data and a time dependent poroelastic model. An iterative approach was build using MATLAB to determine the optimum wellbore trajectory and safe mud window. Mechanical Earth Model was constructed using log data. Wellbore stresses were determined using the poroelastic constitutive model. Modified Lade Criterion was used to determine the failure conditions of the wellbore walls. The results of the developed model were validated against actual well log data from Gulf of Suez, Egypt.
