The PDF file of this paper is in Russian. The article presents the experience and results in constructing a full-scale integrated (reservoir - well - infrastructure) model of a large oil-gas-condensate field, including a set of models of oil rims and gas caps for the main objects of development, gas reservoirs, models of wells and downhole equipment, as well as model of the surface network system for collecting and transporting products to the central processing unit and the gas re-injection system from the gas compressor station of the gas processing facility. The objective of this article is the coverage of the results of creating a full-scale integrated model of gas reservoirs and gas caps of the field. The task including creating, history matching and integration of the reservoir models with surface facility system, the elimination of "bottlenecks" in the gas facility network system and the determination of the optimal solution to the problem of hydrocarbon production (oil production from oil rims and gas production from gas caps and dry gas formations together). Conducted integrated calculations allowed us to consistently identify and minimize the risks associated with the geological potential of productive formations and throughput capacity of the gas pipeline system in the early stages of project development, which leads to an increase in the value of the project. In addition, up-side cases for optimizing the business case were calculated on an integrated model, which increased potential gas and condensate production and the value of the project.

The PDF file of this paper is in Russian. As the petroleum industry development trend suggests by 2025 a significant part of Gazprom Neft's hydrocarbons production will be provided by oil and gas condensate fields with oil rims and complex geological structure. By that time, the share of production from green fields will reach 50%. Given the complexity of such fields, the success of development projects will depend on the quality of consideration and efficiency of interrelated solutions for both field development and infrastructure facilities configuration. This paper presents the experience in building a full-scale integrated model of a large oil-gas-condensate field, which includes models of oil rims for the main reservoirs, models of wells and downhole equipment, model of the fluid gathering and transportation system including the main transfer pumping station, and model of the gas reinjection system including the gas treatment facility compressor station. The goal of the work is to find a balanced solution for oil well operation parameters taking into account the constraints imposed by the infrastructure. Integrated modeling is aimed at improving the project planning and production profile prediction quality by combining the models of the reservoir, wells, fluid gathering networks and surface infrastructure facilities into a single generic model. Development and implementation of this model that considers together the processes occurring in the reservoir and the surface networks, and takes into account infrastructure facilities' operation constraints such as velocity of gas-liquid mixture in production tubing and in flowlines of the oil and gas gathering systems, constraints existing in the Gas Treatment Facility and Oil Treatment Facility, loop lines and bridges in pipeline systems, ensures higher quality of project decisions. The working platform for the integrated model is the RESOLVE software package in combination with the GAP, Prosper and tNavigator simulation products.

Abstract The new green fields of Yamal region and Eastern Siberia today is one of the important areas for oil production during next 10 years. One of the key problems of field development in these regions is poor infrastructure and lack of input data of geology, target formations and fluids properties. For decision making during field development preparation stage its necessary to carry out estimation of possible scenarios. Analysis of uncertainty will provide a range of changes in reserves and oil production profiles which can help to estimate economical part of field development project. Also these results can be used for design pipe lines and surface facilities. Authors of paper suggested the approach how to estimate uncertainties in cases of lack input data of formation based on data of Russkoye oil field.
