Abstract Reservoir characterization is often a demanding and complicated task due to the nonlinear heterogeneous physical properties of subsurface environment. Those issues can be overcome accurately efficiently by use computer-based intelligence methods such as Neural Network, Fuzzy Logic Genetic Algorithm. This paper will describe how one integrates comprehensive methodology data mining techniques artificial neural network (ANN) in reservoir petrophysics prediction regeneration. Density...

Summary A new unified gas-transport model has been developed to characterize single-component real-gas flow in nanoscale organic and inorganic porous media by modifying the Bravo (2007) model. More specifically, a straight capillary tube is characterized conceptual layered consisting of viscous-flow zone, Knudsen-diffusion surface-diffusion zone. To specify contributions viscous Knudsen diffusion gas transport, virtual boundary between zones first determined using an analytical...

The phase behavior of fluids in nanopores deviates significantly from that bulk space. However, the effect pore confinement on capillary condensation has not been fully understood. In this work, classic Kelvin equation is modified by incorporating real gas effect, along with size surface tension, multilayer adsorption, and molecule–wall interaction potential to improve its accuracy calculating pressure. further extended for multicomponent nanopores. More specifically, an Peng–Robinson state...

The iterative ensemble smoother (IES) algorithm has been extensively used to implicitly and inversely determine model parameters by assimilating measured/reference production profiles. performance of the IES algorithms is usually challenged due simultaneous assimilation all data multiple iterations required for handling inherent nonlinearity between profiles parameters. In this paper, a modified proposed validated improve efficiency accuracy with standard test (i.e., PUNQ-S3 model). More...

Abstract Phase behavior in nanopores, because of its widespread industrial applications, has attracted great attention from numerous researchers recent years. However, there are still several aspects that not fully understood this area, such as the confinement effect on saturation pressure, critical properties, and phase boundary. In work, real gas is firstly incorporated into original Kelvin equation, along with pore size surface tension, multilayer adsorption, molecule-wall interaction...

Summary Existing rarefied gas flow models cannot accurately characterize behaviors in nano-porous media by coupling various empirical rarefaction and diffusion coefficients. Also, almost all overlook the importance of non-ideal effect on flux apparent permeability. In this work, a unified model for nonideal has been developed. More specifically, straight capillary tube consisting viscous zone Knudsen is sectioned an analytically derived boundary. Subsequently, permeability obtained weighted...

Abstract A common practice in gas-shale reservoir simulation, which arbitrarily increases intrinsic matrix permeability to match the production data, has been proven inefficient and unreliable. Alternatively, accurate estimations of gas apparent (AP) is desired. This work presents an analytical AP model considering rarefaction nanopores coupling experimentally confirmed mechanisms shale for theoretical completeness. Meanwhile, physical terms are simplified with semi-empirical correlations...
