Strengthen a wellbore while drilling is the most effective technique to do to the wellbore before bad losses will be happened. Techniques of wellbore-strengthen are similar to lost circulation concepts. The wellbore-strengthen techniques emphasize on lost circulation prevention, increase in overall formation fracture gradient and elimination of fracture elongation. However, the lost circulation concepts focus on preventing losses of drilling fluid. In the drilling industry, 7 effective ways to strength the wellbore are as follows;
