The performance of complex-structure fractured reservoirs considering natural and induced matrix block size, shape, and distribution

Al-Rbeawi, Salam
This paper introduces an analytical approach for the performance of the fractured reservoir considering the impact of the matrix block size, shape, and distribution. The objective is better understanding the roles of the variable interporosity flow systems, fracture flowing systems, and reservoir matrix heterogeneity in the responses of the wellbore pressure drop, flow rate, cumulative production, and productivity index. This understanding could help to eliminate the uncertainties and increase the accuracy in characterizing the conventional and unconventional reservoirs where very complex structures of a significant disorder in the matrix block size, shape and distribution could be existed in the porous media.


The impact of spatial and temporal variability of anomalous diffusion flow mechanisms on reservoir performance in structurally complex porous media
Al-Rbeawi, Salam (Elsevier BV, 2020-06-01)
The main objective of this paper is understanding the phenomenal anomalous diffusion flow mechanisms in unconventional fractured porous media. The targets are hydraulically fractured unconventional reservoirs characterized by porous media with scomplex structures. These media are consisted of a matrix and naturally induces fractures embedded in the matrix as well as hydraulic fractures.
The effect of fractures on the steam-assisted gravity drainage process
Bağcı, Ali Suat (American Chemical Society (ACS), 2004-11-01)
This study presents an experimental investigation of the effect of fractures and well configurations on the steam-assisted gravity drainage (SAGD) process in a three-dimensional model, using 12.4degreesAPI gravity crude oil. A total of eight runs were conducted, using a 30 cm x 30 cm x 10 cm rectangular-shaped box model. Temperature distributions were observed using 25 thermocouples. Three different well configurations were investigated-a horizontal injection and production well pair, a vertical injection-v...
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...
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 ...
Fluid flux throughout matrix-fracture interface: Discretizing hydraulic fractures for coupling matrix Darcy flow and fractures non-Darcy flow
Al-Rbeawi, Salam; Owayed, Jalal F. (Elsevier BV, 2020-01-01)
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...
