Flow-Regime-Based Inflow-Performance Relationships of Unconventional Fractured Reservoirs

Al-Rbeawi, Salam
The main objective of this paper is to develop a new approach for constructing the inflow-performance relationships (IPRs) of unconventional reservoirs. The proposed approach focuses on using transient- and pseudosteady-state-flow regimes in developing integrated analytical models for wellhead deliverability and wellbore-pressure decline considering the two wellbore conditions, constantsandface-flow rate and constant wellbore pressure. The motivation is to reduce the uncertainties in predicting current and future performance of unconventional reservoirs.


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...
Reservoir analysis by well log data
Kök, Mustafa Verşan; Ersoy, Gizem (Informa UK Limited, 2005-04-01)
The aim of this research is to describe and characterize the reservoir sections by well log data. Well logs are used to examine the porosity, water saturation and true resistivity properties of the reservoir. Throughout the project, the data is processed using geostatistical tests that are frequency, histograms, auto-correlation, cross-correlations, linear and multiple regression analysis to find the relations between the variables. Statistical analyses are performed using SPSS software. From the output of ...
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 ...
Limitations of three-phase Buckley-Leverett theory
Akın, Serhat (Informa UK Limited, 2005-07-01)
The broad objective of this study is to determine the limitations of the three-phase relative permeability estimation technique by using the experimental approach. In order to achieve this goal, three-phase relative permeability experiments were conducted on a Berea sandstone core plug by using brine, hexane and nitrogen gas. An unsteady-state analytical technique and a numerical technique where a black oil simulator was coupled with a global optimization algorithm in a least squares manner was used to comp...
