Uncertainty Quantification in 1d Pore Pressure Prediction of Exploratory Wells
Palavras-chave:
Pore Pressure, Uncertainty Quantification, Sensitivity AnalysisResumo
The pore pressure model serves as a subsidy for the well project, predicting potential risk events. Events
such as stuck pipe and inflow of fluids into the well result in a high cost in exploratory oil projects, either due to
the time spent fighting them, or the complete loss of the well. Unfortunately, in exploratory projects we do not
have enough data, nor the indirect data have good reliability, therefore, these models have high uncertainties. The
present work proposes the application and evaluation of the uncertainty and sensitivity analysis methodology in
the 1D pore pressure models used in the drilling of exploratory oil wells, to quantify and measure their impact. For
this purpose, data from wells drilled in the Santos Basin, southeastern Brazilian margin, were used.
