Reservoir analysis by well log data

Kök, Mustafa Verşan
Ersoy, Gizem
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 the software, the data of the reservoir section would be improved resulting in a higher efficiency in the usage of the data.

Flow-Regime-Based Inflow-Performance Relationships of Unconventional Fractured Reservoirs
Al-Rbeawi, Salam (Society of Petroleum Engineers (SPE), 2020-08-01)
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 ...
Rheological properties of asphaltite-water slurries
Hicyilmaz, Cahit; Ozun, Savas; Altun, Naci Emre (American Chemical Society (ACS), 2006-09-20)
In this study, the rheological characteristics of asphaltite- water slurries ( AWSs) were investigated with respect to some of the most important parameters in the preparation of slurries. The effects of pulp density, chemical addition, pulp pH, and particle size on the rheological behavior and viscosity of AWSs were studied. The role of demineralization of asphaltite was also investigated, and rheological properties of raw and relatively demineralized asphaltites were compared. Results showed that viscosit...
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...
Rheological and thermal analysis of bentonites for water base drilling fluids
Kök, Mustafa Verşan (Informa UK Limited, 2004-02-01)
The objective of this research is to investigate the rheological and thermal properties of bentonites for water base drilling fluids. Rheological experiments were performed with 4 different bentonite samples and clay percentages, cation-exchange capacity (CEC), swelling volume, pH, and physical and rheological properties of the samples are determined. The thermal behaviors of bentonite samples were investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) techniques. ...
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 ...
