... content and carbohydrate content of the return waters as a function of residence time under simulated reservoir conditions. Preliminary indications are that more sophisticated information can be obtained by the use of emerging analytical techniques such as high pressure liquid chromatography (HPLC...

.... An alternative to parametrization is to use prior geological information in the form of a prior probability density of the reservoir properties probability density of the reservoir properties considered as random variables. A form of Bayesian estimation then can be employed to determine the unknown properties...

... as an alternative to zonation. By using a priori statistical information on the unknown parameters, the problem becomes statistically better determined. Bayesian estimation and zonation are applied to the problem of porosity and permeability estimation in a one-dimensional, permeability estimation in a one...
