We developed two new EOS additions to the TOUGH+ family of codes, the RealGasH2O and RealGas. The RealGasH2O EOS option describes the non-isothermal two-phase flow of water and a real gas mixture in a gas reservoir (including a tight/shale gas one). The gas mixture is treated as either a single-pseudocomponent having a fixed composition, or as a multicomponent system composed of up to 9 individ...

Tight, low-porosity reservoirs can produce significant amounts of hydrocarbons if fracture networks provide the necessary permeability. Characterization of naturally fractured reservoirs using surface seismic data is an important exploration problem that has attracted much attention in the literature. TLE, for example, had an entire issue (August 1996) on this subject. While the data and modeli...

analytical solutions and type curves for the constant rate radial flow of fluid in both conventional and naturally fractured reservoirs including the effect of wellbore phase redistribution are presented. an automated procedure for non-linear least square minimization using the analytical solutions and their derivatives with respect to the unknown parameters developed to analyze the pressure bu...

RESULTS Drilled four wells based on the model, successfully predicting the type and thickness of reservoir facies, enabling the operator to pursue optimal field development strategies with higher confidence in the distribution and connectivity of critical flow units. Modeling reservoir architecture with limited data After successfully developing Cretaceous reservoirs in several northern Kuwait ...

Fluid-solid coupling is ubiquitous in the process of fluid flow underground and has a significant influence on the development of oil and gas reservoirs. To investigate these phenomena, the coupled mathematical model of solid deformation and fluid flow in fractured porous media is established. In this study, the discrete fracture model (DFM) is applied to capture fluid flow in the fractured por...

Fractured-vuggy reservoirs are a new target in carbonate oil and gas exploration development. Because of well-developed reservoir bodies, including fractures caverns, bottom water invasion can be observed oilfield development, with low utilization efficiency crude the reservoir. Accordingly, this study focused on intersection region S99 unit Tahe fractured-vuggy reservoirs. Based seismic data, ...

Phase transformation affects multiphase flow in geothermal and gas-condensate reservoirs due to the same substance occurring in different phases. These effects change the phase behavior and the flow characteristics. The goals of this research were to compare the flow behavior and relative permeabilities difference between two-phase flow with and without phase transformation effects in smooth-wa...
