This article covers the issue of the geological simulation quality improvement as a result of geologist and reservoir engineer interaction during the simulation process. The article includes case studies providing examples of the reservoir simulation quality improvement based on the detailed reservoir structure. Source

The article dwells on the problem of simulating discontinuous solutions in numerical models as exemplified by the oil-water displacement problem in porous medium with neglected capillary pressure (Buckley-Leverett problem). It has been shown that coarse sampling in numerical models enhances the process of numerical diffusion, leading to "blurring" of the displacement front. The work presents a new method to regularize the numerical solution of the water-oil displacement problem in porous medium by scaling the relative permeability functions, which enables reconstruction of the displacement front's movement using coarse grid with no changes in the numerical scheme. The carried out test calculations have confirmed the applicability of this method. Source

The article recites the data on solving problem that relates to necessity to compare lithologic and facies columns and electrometric models in wells done by various authors within one work area in order to build lithological and facies model. The conclusions are made about differences in approaches used to determine zoning. Based on the analysis, the scale of facies zones is proposed that specifies values of certain terms in various classifications. Source

In Cenozoic time changes of vertical and lateral direction of tectonic processes took place within Demyanskiy megaarch and adjoining depressions. Structural trends orientation changed from north-western to north-eastern and regional down movements gave way to uplifting and partial erosion of previously accumulated sediments. Structural changes of main Jurassic and cretaceous oil-and-gas bearing horizons in Cenozoic time affected hydrocarbons lateral migration pathways and source rocks maturity distribution.

A problem of the influx of fluid to the well crossed by hydraulic fracturing is reviewed. The author researched processes of joint motion of fluid in the system of reservoir-fracture-well. On the basis of the realized numerical 2nd grid model, considering a filtration in the presence of cracks the sector site of a real field with the hydraulic fracturing address program is calculated.
