Many fields demonstrate significant vertical changes in the oil properties. It is a challenge to explain and simulate these changes which occur under the gravitational forces or the effect of thermal diffusion if the reservoir is thin (up to 40 m) and the temperature gradient is close to zero, which is typical of some fields in East Siberia. Here, other processes have a significant impact on the properties of oil: oxidation, biodegradation, the effect of bottom water near the oil-water contact, etc. At the same time, ignoring the differentiation of oil properties in a flow simulation model (setting averaged properties for the entire reservoir) leads to an incorrect assessment of fluid mobility and to inaccurate estimates of hydrocarbon production volumes. The paper presents an approach to creating a PVT-model for systems with vertical differentiation of oil properties in the context of one of the reservoirs of the Srednebotuobinskoye field. The analysis of field geological information allows the authors to identify a layer of heavy viscous oil near the water oil contact. Previously the samples with high viscosity values had been ignored as non- representative. Matching the common equation of state to the results of some samples which were taken both near the gas oil contact and water oil contact helps to take fluid properties differentiation by depth into accountโ fully saturated oil at the gas oil contact and increasing the oil viscosity in the vicinity of the water oil contact. As a result the compositional dynamic model allows to determine oil properties correctly in a reservoir when estimating hydrocarbon reserves, improve history matching process and provide a more accurate predicted HC production.

Abstract A case study of a gas-condensate field located on the northeastern shelf of Sakhalin Island demonstrates the possibility of development of condensate-containing gas reserves by drilling very long ERD wells (drilling from the shore). The development system described in the paper includes drilling well with upward orientation. Such design provides complete cleaning of a wellbore from fluids and solids accumulated over a long period of maintenance-free operation. The choice of a development system using horizontal wells is also associated with the geological structure of the field (massive type accumulation with a single gas-bearing contour is broken by tectonic faults into separate blocks with different hypsometric elevations). Under the technical, economical (drilling from platform and from land, the use of subsea production systems, ice gouging with hummocks), and environmental (presence of valuable fish species in water areas and permanent residence of indigenous peoples) limitations, the development of individual wells with vertical completions turned out to be unprofitable. For the first time for this type of accumulation located in a coastal zone, a unique method of monitoring the recovery of reserves within the cross-section, as well as movement of the gas-water contact without the use of monitoring and pressure observation wells was suggested.

Abstract Specific of gas field development suggests a constant level of gas production in order to provide stable loading of gas field processing and transport facilities. At this point, when production of major development objects commences to fall, start of minor objects production is supposed to occur. Having united surface facility and separate reservoir simulation of segregated layers with joint well stock a question of accuracy in measurement of hydrocarbon production is arisen. In addition, at the entry of production of minor objects with distinctive reservoir pressure a problem of appropriate distribution of wellhead and downstream pressures can be revealed. In this paper mechanism of building of a multiple layer oil and gas condensate field integrated simulation model (ISM) is described. Construction of integrated model will allow resolving the problems outlined above. Besides, running of field development simulation cases with different order and tempo of production will be significantly simplified. Separate compositional models made for each development object have been selected for integration in the ISM. However, consolidation of these models is complicated by the issue of demanding a lot of resources for storage and computation time. Therefore, a transition from compositional to black oil models has been performed in order to obtain production data. Detailed gas composition required for integration with a gas processing system can be gained by a delamping procedure. As a result of building integrated simulation model a flexible tool of effective management of field development has been obtained that makes it possible to run simulations for both major and minor objects simultaneously and taking into account the field infrastructure (gathering and compressor facility); to assess the possibility of joint production of separate layers and consider the impact of gathering system on hydrocarbon production as well. When comparing the simulation time in different types of models, without significant loss of simulation quality, the average acceleration is about twenty times. This allows obtaining results much faster and further improving it.

Abstract The paper investigates the processes of condensate recovery from low-permeable formations during depletion-driven development of gas-condensate deposits. The studies were based on simulating multi-component flow of various gas-condensate mixtures in reservoirs with a large range of permeabilities. As a result, the key causes of decreased condensate recovery from low-permeable formations compared to "regular" reservoirs have been established. It was shown that for low-permeable formations, due to large pressure drawdown cones, the additional condensation of C5+ components because of an "non equilibrium" effect is possible, where the flowing gas phase is out of equilibrium to the retrograde condensate. The main technological factors influencing the condensate recovery from low-permeable formations were identified, as well as possible ways to increase condensate recovery.

Abstract Using BU16 formation of the Urengoy oil and condensate field deposit as an example the authors have demonstrated that today in the absence of developed transport infrastructure high CAPEX and OPEX investments are inevitable. It will result in negative economic results in developing oil banks in gas and condensate deposits located in the Northern and Polar regions of the Russian Federation. This factor decreases attraction of such assets for investors significantly and actually oil reserves in oil banks and gas reserves in gas caps are not developed and it is uncertain when these reserves might be developed. As a result the state will get less revenue from developing hydrocarbon reserves.
