http://www.maths-in-industry.org/miis/33/ Uncertainty of flow in porous media Aitchison, Joyce Cummings, Linda Richardson, Giles Rougier, Jonathan Energy and utilities Materials The problem posed to the Study Group was, in essence, how to estimate the probability distribution of f(x) from the probability distribution of x. Here x is a large vector and f is a complicated function which can be expensive to evaluate. For Schlumberger's applications f is a computer simulator of a hydrocarbon reservoir, and x is a description of the geology of the reservoir, which is uncertain. 2005-01-14 Study Group Report NonPeerReviewed application/pdf http://www.maths-in-industry.org/miis/33/1/UncertainPorousFlow.pdf http://www.smithinst.ac.uk/Projects/ESGI49/ESGI49-Schlumberger/Report/UncertainPorousFlow.pdf Aitchison, Joyce and Cummings, Linda and Richardson, Giles and Rougier, Jonathan (2005) Uncertainty of flow in porous media.
