Summary Rate-transient analysis (RTA) is a useful reservoir/hydraulic fracture characterization method that can be applied to multifractured horizontal wells (MFHWs) producing from low-permeability (tight) and shale reservoirs. In this paper, we applied a recently developed three-phase RTA technique to the analysis of production data from an MFHW completed in a low-permeability volatile oil reservoir in …

Abstract Recently unconventional gas resources including the shallow biogenic gas reservoirs have received great attention around the world due to technical advances in the field development and corresponding large in-place resources. However, the technologies needed for the effective development of unconventional reservoirs are still behind the industry needs, for example the gas recovery rates from …

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 …
