The objective of this paper is focusing deep insights on reservoir fluid flux from a structurally complicated matrix to non-uniformly propagated hydraulic fractures. A hypothetical unconventional reservoir is considered with stimulated and un-stimulated reservoir volume. A Semi-analytical multilinear flow regimes model is developed for pressure distribution by coupling matrix Darcy flow model and hydraulic fracture non-Darcy flow model. Hydraulic fractures are discretized to several segments with a specific fluid flux to these segments. The study has reached to several conclusions such as: fluid flux from SRV matrix to hydraulic fractures may have a significant impact on reservoir performance and discretizing hydraulic fractures to several segments may give different pressure behavior, flow rate, and productivity index than single segment fracture. The novel point presented in this study is presenting a semi-analytical model that couples matrix Darcy flow and hydraulic fracture non-Darcy flow using trilinear dual porosity model and discretizing hydraulic fractures.

Pseudo-steady state inflow performance relationship of reservoirs undergoing multiphase flow and different wellbore conditions Al-Rbeawi, Salam (Elsevier BV, 2019-08-01) This paper introduces an integrated approach for the inflow performance relationship of reservoirs that undergo multiphase flow conditions and drained by vertical wells with different wellbore conditions. The main objective is eliminating uncertainties that govern predicting reservoir performance by assuming single phase flow in the porous media. The proposed approach includes developing several models for multiphase flow conditions using PVT data and relative permeability curves. These models are assembled...
Integrated analysis of pressure response using pressure-rate convolution and deconvolution techniques for varied flow rate production in fractured formations Al-Rbeawi, Salam (Elsevier BV, 2018-03-01) This paper introduces an integrated analysis for pressure transient behavior of conventional and unconventional multi-porous media reservoirs considering varied flow rate conditions. It focuses on the applications of pressure-rate convolution and deconvolution techniques for analyzing pressure records of homogenous single porous media, double porous media, and triple porous media reservoirs. The tasks covered in this paper are: Deconvloving pressure response, characterizing and developing analytical models ...
Integrated deterministic approaches for productivity index of reservoirs depleted by horizontal wells and undergone multiphase flow conditions Al-Rbeawi, Salam (Elsevier BV, 2019-04-01) This paper introduces new integrated approaches for estimating pseudo-steady state productivity index (PI) and shape factor of oil and gas reservoirs drained by horizontal wells and dominated by multiphase flow conditions. These approaches couple PVT data, relative permeability curves, and pressure distribution models during pseudo-steady state flow (PSS). The objective is eliminating the uncertainties of applying single phase flow models and substantially comprising the realistic parameters that govern mul...
Mathematical modeling of steam-assisted gravity drainage Akın, Serhat (Society of Petroleum Engineers (SPE), 2005-01-01) A mathematical model for gravity drainage in heavy-oil reservoirs and tar sands during steam injection in linear geometry is proposed. The mathematical model is based on the experimental observations that the steam-zone shape is an inverted triangle with the vertex fixed at the bottom production well. Both temperature and asphaltene content dependence on the viscosity of the drained heavy oil are considered. The developed model has been validated with experimental data presented in the literature. The heavy...
Kinetics of hydrogen generation from hydrolysis of sodium borohydride on Pt/C catalyst in a flow reactor Boran, Asli; Erkan, Serdar; Özkar, Saim; Eroglu, Inci (Wiley, 2013-04-01) Here, we report the results of a kinetic study on the hydrogen generation from the catalytic hydrolysis of sodium borohydride in a differential flow reactor. As catalyst platinum supported on carbon (Pt/C) was used in two forms: either as powder or coated on carbon cloth. For optimization of the system several parameters such as sodium hydroxide concentration, sodium borohydride concentration and the flow rate of the feed solution were varied. It was found that the H2 generation rate increases with an incre...
