Updating the petrophysical model of a thin-layered clay reservoir, taking into account the identified lithofacies features

The article presents a study on the establishment of geological and facies conditions for formation sandy-silty-clayey reservoir based core analysis linking information obtained with neighboring areas. Previously used petrophysical relationships were generalized underlying objects composed thick monolithic sandstones did not allow correctly assessing properties under consideration. work made it possible to clarify idea lithofacies features substantiate their own dependencies, which make differentiate thin-layered clay reservoirs in section determine properties. results during refine model, previously all layers group. revision boundary values dependencies helped justify increase oil reserves became basis subsequent profitability putting facility into commercial development.
