Abstract

The ultimate objective of this thesis is to develop a technique for directassessment of reservoir flow performance uncertainties, as compared to manytraditional, computationally expensive techniques such as Monte Carlo simulations. This is achieved via a single stochastic flow simulation that combineslocal geologic uncertainty with a new simple flow transfer model to estimate a joint uncertainty distribution that characterizes flow uncertainty. Our methodprovides the framework to go directly from local uncertainty, derived using simple spatial interpolation techniques, to flow uncertainty, skipping the intermediate step of stochastic sequential simulations and not requiring any detailed fine-scale flow simulations.
