Drilling problems and solutions

Even with very carefully planned wells, it is almost possible to have problems while drilling the well. For example, in areas where similar drilling practices are used, well problems may be reported where there were no such problems before, because the formations are not homogeneous. Therefore, two wells close to each other may have completely different geological formations.

In order to control the total cost of the wells and reach the target zone, it is necessary to understand and anticipate drilling problems, to investigate their causes and solutions.
