Revisiting The Butler-Mokrys Model For The Vapor-Extraction Process, Vijitha Mohan, Partho Neogi, Baojun Bai Apr 2019

Revisiting The Butler-Mokrys Model For The Vapor-Extraction Process, Vijitha Mohan, Partho Neogi, Baojun Bai

Chemical and Biochemical Engineering Faculty Research & Creative Works

The dynamics of a process in which a solvent in the form of a vapor or gas is introduced in a heavy-oil reservoir is considered. The process is called the solvent vapor-extraction process (VAPEX). When the vapor dissolves in the oil, it reduces its viscosity, allowing oil to flow under gravity and be collected at the bottom producer well. The conservation-of-species equation is analyzed to obtain a more-appropriate equation that differentiates between the velocity within the oil and the velocity at the interface, which can be solved to obtain a concentration profile of the solvent in oil. We diverge from …


Preformed Partial Gel Injection Chased By Low-Salinity Waterflooding In Fractured Carbonate Cores, Ali K. Alhuraishawy, Baojun Bai, Mingzhen Wei, Abdullah Almansour Feb 2019

Preformed Partial Gel Injection Chased By Low-Salinity Waterflooding In Fractured Carbonate Cores, Ali K. Alhuraishawy, Baojun Bai, Mingzhen Wei, Abdullah Almansour

Fractures and oil-wet conditions significantly limit oil recovery in carbonate reservoirs. Gel treatment has been applied in injector wells to modify the prevailing reservoir streamlines and significantly reduce fracture permeability, whereas low-salinity waterflooding has been applied experimentally to modify rock wettability toward water-wet for improved oil recovery. However, both processes have limitations that cannot be resolved using a single method. The objective of this study was to test whether low-salinity water could enable gel particles to move deeply into fractures to efficiently increase oil recovery and control water production. A semitransparent fracture model of carbonate cores and acrylic plates was …


Separation Of The Petroleum System, Ali Ibrahim Neamah Jan 2015

Separation Of The Petroleum System, Ali Ibrahim Neamah

The Hilltop Review

This study discusses the overall process of crude oil separation as well as the necessary equipment used in the process. Also discussed and analyzed are potential issues seen in the crude oil extraction process. Reasons why these operation problems may occur are analyzed as well as treatment options for such occurring issues are discussed for employees and students alike. This research is based off of personal involvement at the Nasiriyah Degassing Station located in Dhi Qar, Iraq.


Measurements And Modeling Of Hydrocarbon Mixture Fluid Properties Under Extreme Temperature And Pressure Conditions, Babatunde A. Bamgbade Jan 2015

Measurements And Modeling Of Hydrocarbon Mixture Fluid Properties Under Extreme Temperature And Pressure Conditions, Babatunde A. Bamgbade

Theses and Dissertations

Knowledge of thermodynamic fluid properties, such as density and phase behavior, is important for the design, operation, and safety of several processes including drilling, extraction, transportation, and separation that are required in the petroleum. The knowledge is even more critical at extreme temperature and pressure conditions as the search for more crude oil reserves lead to harsher conditions. Currently, there is dearth of experimental data at these conditions and as such, the predictive capability of the existing modeling tools are unproven. The objective of this research is to develop a fundamental understanding of the impact of molecular architecture on fluid …


A Framework For Oil Price Benchmark Determination: Lessons For Nigeria, Taiwo H. Sanni, Bassey D. Akpan Mar 2013

A Framework For Oil Price Benchmark Determination: Lessons For Nigeria, Taiwo H. Sanni, Bassey D. Akpan

Bullion

The main thrust of this paper is to draw lessons of experience from other selected oil producing countries. the outcome of the study is expected to help in strengthening Nigeria's oil price framework in line with international best practice. Section 2 dwells on the theoretical and literature review on oil based fiscal rule, while section 3 presents the framework for oil price benchmark determination and section 4 examines those factors capable of stimulating determination of oil price benchmark, lastly section 5 discusses some lessons of experience from Nigeria and then the conclusion.


Preparation Of Cobalt/Nickel Molybdenum Sulfide Catalysts Supported By Aqueous Media Soluble Multi-Wall Carbon Nanotubes., Hassan Ahmad Bleibel Jan 2013

Preparation Of Cobalt/Nickel Molybdenum Sulfide Catalysts Supported By Aqueous Media Soluble Multi-Wall Carbon Nanotubes., Hassan Ahmad Bleibel

Open Access Theses & Dissertations

Multi-walled carbon nanotubes (MWCNTs) have been subjected to chemical treatment in order to introduce hydrophilic functional groups on their surfaces. These covalently bonded groups did enhance the solubility of MWCNTs in aqueous media as expected. Functionalized MWCNTs were characterized using FTIR, Raman spectroscopy, TGA, X-ray diffraction, dispersion test and TEM. Then, functionalized MWCNTs were incorporated in the hydrothermal synthesis method of transition metal sulfide catalysts (CoMo, NiMo, and Ethylenediamine-CoMo Sulfides). Catalysts were characterized using X-ray diffraction, TEM, SEM, N2 Gas adsorption-desorption, elemental analysis, and Hydrodesulfurization (HDS) reaction of dibenzothiophene (DBT). The objective was to study the functionalized MWCNTs' effect; being …
