Previous pore pressure prediction approaches often considered a shallow overpressure associated with a high fracture gradient (FG), and thereby allowing an assumption for a wide operational mud...

... Abstract The pore pressure prediction is the most important process in the design of drilling wells. This paper depicts a new methodology to analyze pore pressure based on both, the normal compaction theory of sediments and the way that normal behavior diverges when it is interrupted. Much has...

Key information such as resulting pore pressure and effective stresses can be easily computed along the fracturing process. Once obtained results are compared to analytical solutions and experimental...
