Ex: A well is need to be drilled to 15,000 ft. The entrance into abnormal pressures at 10,000 ft are caused by under compaction. Calculate the Density of drilling mud needed to be prepared. Assume that the normal formation pressure gradient are 0.465 psi/ft, porosity and density of compacted formation is 8% and 2.65 gm/cc respectively and fluid density in the compacted formation is 1.04 gm/cc. Surface Depth Decreasing porosity Rock matrix and porosity 10000 ft Barrier 15000 ft PHON Normal pressure Abnormal pressure Undercompacted region (Greater than normal porosity)
