Abstract
In this study, an analysis of the density tool’s and the sonic tool’s associated uncertainty is presented that shows how these measurement related uncertainties propagate forward into conventional overburden and pore pressure gradient calculations. The tool based random uncertainties ultimately create a statistically reliable range for pore pressure estimations. While breakthroughs in analytical technique are likely possible in the future, reduction of the random error by measurement cross-validation and integration is shown to be an achievable outcome without any improvements in the current technology.
