... Abstract This paper presents the results of an investigation of shear and compressional velocities and their ratios for pore-pressure prediction in a subsalt environment. In this work, we introduced the state of the art in the analysis of acoustic methods—compressional velocity (Vp), shear...

..., petrophysical, and drilling data. This database was used to develop best practices for pore-pressure estimation below salt. In this work, both conventional and unconventional pore-pressure prediction methods—including acoustic and resistivity methods—were applied, tested, ranked, and evaluated against known...

... Abstract The art and science of pore pressure prediction has improved dramatically over the last 10 years with major advances in the areas of imaging and velocity analysis and in the theory of pore pressure in clastic basins. This paper discusses the current state of pore pressure theory...

... Abstract Porosity based pore pressure prediction is based on mechanical compaction of fine-grained sediments with known compressibility behavior. The pitfalls of the prediction methods relate to several challenges in describing overpressured rocks. Firstly, techniques which compare porosity...
