Gas-condensate flow is a critical process in the near-well region where well production efficiency strongly affected by of condensate dropout. Pore-scale simulations have provided an understanding underlying processes such as snap-off and effect interplay between viscous capillary forces on gas-condensate its induced blockage within pore spaces. Among various modeling approaches used to explore these phenomena, pore-network modeling, due computational ability simulate relatively large sample...

Asphaltene is a complex macromolecule whose abundance strongly affects the physical and interfacial properties of crude oil. molecules may precipitate during oil production/transportation, which lead to plugging/clogging wellbores, pipelines, equipment. In this study, solubility asphaltene in toluene has been investigated by calculation noncovalent interaction energies between asphaltenes medium. The results study revealed that main interactions asphaltene-toluene system are Lifshitz-van der...

When it comes to the economic efficiency of oil and gas field development, finding optimum well locations that augment an economical cost function like net present value (NPV) is paramount importance. Well location optimization has long been a challenging problem due heterogeneous nature hydrocarbon reservoirs, criteria, technical uncertainties. These complexities lead enormous number possible solutions must be evaluated using evaluation (e.g. simulator). This makes necessary develop...

Abstract Fracturing is one of the most common well stimulation techniques especially for tight gas-condensate reservoirs. Gas condensate flow around hydraulically fractured wells (HFWs) different from conventional gas oil systems. This mainly due to phase change, drop out and coupling (i.e., increase relative permeability as velocity increases and/or interfacial tension decreases) inertial reduction increases) effects. Description HFWs in reservoirs using existing reservoir simulators...

Abstract Hydraulic fracturing is one of the most common well stimulation techniques. Hence, considerable amount efforts has been devoted to study their performance under different prevailing conditions. Description hydraulically fractured wells using existing commercial reservoir simulators requires use very fine grids, which cumbersome, costly and impractical. In this work a two dimensional single-well mathematical simulator developed, based on finite-difference methods, simulates linear...

Abstract An optimized design for hydraulic fracturing is of great importance especially with the growing demand this method as a means production enhancement from tight gas reservoirs. The first optimum fracture (OFD) approach, which maximizes well productivity given volume, was introduced by Prats in 1960 single-phase Darcy flow systems. This method, later modified and presented form Unified Fractured Design (UFD) charts other investigators, widely used petroleum industry, even condensate...

Abstract An interaction energy model is employed to discern the roles of liquid composition and asphaltene properties on stability. The determines Lifshitz‐van der Waals (LW) acid‐base (AB) for two asphaltenes A B types with different polarities synthetic oils nC 7 volume fractions. results indicate that loses its solubility increased fraction, due reduction in electron donor component. Moreover, at very beginning addition, both show a similar resistance against aggregation, rates change...

Abstract In this paper, a new compositional mechanistic wellbore model, including gas lifting parameters, is presented. the governing equations of terms for mass transfer between phases and enthalpy phase change, which are important in non-isothermal lift systems, have been considered. These ignored some recent research studies subsequent results show that by ignoring them, serious errors may arise. current study, using drift-flux approach, pressure distribution was modeled. To verify...

Abstract The fundamental objective of this study is to utilize a temperature dataset achieve accurate rate estimation. This introduces graphical method, incorporating suitable assumptions, for predicting flowrates in single-phase vertical oil flow. method takes into consideration the fouling factor and addresses steady-state flow heat wellbore, while also accounting transient conduction formation. To evaluate validate proposed model, two field cases are examined, associated uncertainties...
