CRITICAL REVIEW ON EFFECTS OF PORE TYPE CLASSIFICATIONS ON PORE PRESSURE AND ITS ESTIMATION TECHNIQUES

Determining pore pressure is one of the main vital factors to be considered in a pre-drilling phase of each development plan. This is because with the right pore pressure estimated, proper casing design and drilling fluid can be used which in turn can save money, lives and environments. If wrongly p...
