Abstract The construction of unified compositional model is important for modeling of production surface network. The produced streams are described by different multicomponent PVT models, while total production calculation requires a single consistent PVT system. The method for constructing a compositional model which is optimal in terms of components number is proposed. As a first …

Abstract In this paper we propose a novel method of reducing the number of history matching variables required for adequate approximation of static properties associated with reservoir models of hydrocarbons. The method is based on the expansion of the static parameters into discrete orthogonal basis with subsequent parametrization of underling expansion coefficients. The method is …

Abstract The article considers the first successful example of the UGS operation process modeling based on a saturation parameter derived from well logging data in a multivariant space-time form. Well logging data is a valuable source of information on the actual gas distribution in the UGS reservoirs and on its dynamics during gas injection and …

Abstract A new approach for numerical modeling of a set of compositional dynamic models of oil and gas fields coupled by the same surface network is considered. A unified coupled system of equations is constructed to jointly model reservoir and surface network processes in the method proposed. A new integrated model “reservoir-well-surface network” is a …

Abstract Significant acceleration of the calculations used to create three-dimensional geological and hydrodynamic models is discussed. Detailed 3D models of large and giant reservoirs requires significant computing power for their creation. All available seismic, geological and hydrodynamic data on the oil and gas field, which must be taken into account in a detailed model, require …
