Horizontal wells application in heterogeneous reservoirs is challenging as assumes high expenditures in conditions of problems with such wells modeling. The model matched to history data can show inaccuracy in horizontal wells performance forecast. In this paper the issue is investigated with using of integrated approach. Uncertainties related to reservoir complexity are considered as possible sources of erroneous prediction. Reservoir study coupled with the review of analytical solutions is conducted to identify the uncertain parameters influencing horizontal well performance. Their ranges of variation obtained from research data are included into qualitative analysis of uncertainties impact. It is performed on the model with estimation of oil production as a main decision criterion. All the uncertainties are incorporated into simulation process with using of Monte Carlo technique and automatic history matching. Non-unique nature of the model is shown and the significance of performing multivariant prediction for horizontal wells is proved. As a result the modeling procedure with uncertainties inclusion is proposed and methods of uncertainties reduction are recommended in order to increase model reliability. This will allow uncertainties management and more founded decision making. Copyright 2011, Society of Petroleum Engineers.

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.

Since 2007 in the company of TNK-BP is The System of subsoil use monitoring, which contains information and copies of documents to license parts and fields. The base of licensing and reserves of the company changes annually. Currently there are no interactive graphic database to reflect the real picture of the potential of the company. The report highlights the problem of the development of geo-information module and version of her decision.

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.

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.

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.

The authors have developed and tested computing technology that removes the constraints on the size and detail of reservoir simulation models for large and giant oil fields the number of cells in such models can reach up to 109. This technology is based on the decomposition of large models for sector models and on separate calculations. Algorithm of iterative integration of sector models-Iterative Fitting Boundary Conditions (IFBC) restores the integrity of the full model. This algorithm is more general than option Flux Boundary Conditions (FBC) of reservoir simulators. Computing technology is based on an algorithm IFBC that allows you to create a giant model, "stick together" full of sector models, "implant" sector models in full. Each of the sector models can be created by individual simulator and can have an independent grid.

It is suggested for large and giant fields a method of hydrodynamlcal simulation - models decomposition into the system of sector models, a separate counting In them, and the Iterative conjugation of sector models to preserve the Integrity of the initial modeling object. The algorithm and ways of iterative convergence acceleration are described.
