Understanding Inhibition Of A Biodesulfurization Enzyme To Improve Sulfur Removal From Petroleum, 2018 University of Kentucky
Understanding Inhibition Of A Biodesulfurization Enzyme To Improve Sulfur Removal From Petroleum, Yue Yu
Theses and Dissertations--Chemical and Materials Engineering
The biodesulfurization 4S-pathway is a promising complementary enzymatic approach to remove sulfur from recalcitrant thiophenic derivatives in petroleum products that remain from conventional hydrodesulfurization method without diminishing the calorific value of oil. The final step of this pathway involves the carbon-sulfur bond cleavage from HBPS, and the production of the final products 2-hydroxybiphenyl (HBP) and sulfite, has been recognized as the rate-limiting step, partially as a result of product inhibition. However, the mechanisms and factors responsible for product inhibition in the last step have not been fully understood. In this work, we proposed a computational investigation using molecular dynamic simulations ...

Mechanistic Modeling Of Nanoparticle-Stabilized Supercritical Co2 Foams And Its Implication In Field-Scale Eor Applications, 2017 Louisiana State University
Mechanistic Modeling Of Nanoparticle-Stabilized Supercritical Co2 Foams And Its Implication In Field-Scale Eor Applications, Doris Patricia Ortiz Maestre
LSU Master's Theses
Previous experimental studies show that nanoparticle-stabilized supercritical CO2 foams (or, NP CO2 foams) can be applied as an alternative to surfactant foams, in order to reduce CO2 mobility in gas injection enhanced oil recovery (EOR). These nanoparticles, if chosen correctly, can be an effective foam stabilizer attached at the fluid interface in a wide range of physicochemical conditions.
By using NP CO2 foam experiments available in the literature, this study performs two tasks: (i) presenting how a mechanistic foam model can be used to fit experimental data and determine required model parameters, and (ii) investigating the ...
Vibration Modification To A.P.I. Fracture Short Term Conductivity Testing Procedure, Blake A. Ereaux
Graduate Theses & Non-Theses
The current API Short Term Fracture Conductivity (volume number) testing procedure provided by the American Petroleum Institute doesn't consistently provide repeatable results. For example, in an independent review of three commercial lab results testing the same sample of proppant the variation between the three had a data spread of nearly 80% (Anderson, 2013). Continuing and refocusing the research performed by Kent Blair's thesis "Modifying Fracture Conductivity Testing Procedures" (Montana Tech, 2015), the goal of this thesis is to expand the lab research results on the use of vibration in the cell loading procedure to improve the repeatability of ...
Evaluation Of Methods To Model Hydraulic Fractures In Flow Simulation, 2017 Montana Tech
Evaluation Of Methods To Model Hydraulic Fractures In Flow Simulation, Ben Doleshal
Graduate Theses & Non-Theses
Modern reservoir studies use reservoir simulation to predict future production and plan reservoir development. Due to the increase in production in unconventional reservoirs in recent years, the number of hydraulically fractured wells has risen drastically. The days of using simple analytic techniques to account for the production of a single hydraulic fracture in a vertical well are gone, and the need to be able to model numerous hydraulic fractures in many stages over long horizontals is required.
This brings up the study question of this research: What is the best way to model hydraulic fractures in a flow simulator? There ...
The Effect Of Mineral Composition On Shale Oil Recovery, 2017 Montana Tech
The Effect Of Mineral Composition On Shale Oil Recovery, Andrew Fakhry
Graduate Theses & Non-Theses
Identifying contact angles in porous media is essential for characterizing multiphase flow of fluids in reservoirs. Traditional methods to measure contact angles assume a homogenous structure of reservoir rock; however, microscale pictures by Scanning Electron Microscopes (SEM) show that rock composition varies even inside a single pore. In addition, the preferentiality of oil layer formation is different according to the minerals constituting the reservoir rock. As a result, contact angles have heterogeneous behavior at the pore-scale.
For the purpose of this research, contact angles are measured on the pure minerals that make up the main components of a Bakken reservoir ...
Diagenesis And Formation Stress In Fracture Conductivity Of Shaly Rocks; Experimental-Modelling Approach In Co2-Rock Interactions, 2017 Louisiana State University and Agricultural and Mechanical College
Diagenesis And Formation Stress In Fracture Conductivity Of Shaly Rocks; Experimental-Modelling Approach In Co2-Rock Interactions, Abiola Olukola Olabode
LSU Doctoral Dissertations
In large scale subsurface injection of carbon dioxide (CO2) as obtainable in carbon sequestration programs and in environmentally friendly hydraulic fracturing processes (using supercritical CO2), long term rock-fluid interaction can affect reservoir and seal rocks properties which are essential in monitoring the progress of these operations. The mineralogical components of sedimentary rocks are geochemically active particularly under enormous earth stresses, which generate high pressure and temperature conditions in the subsurface. While geomechanical properties such as rock stiffness, Poisson’s ratio and fracture geometry largely govern fluid flow characteristics in deep fractured formations, the effect of mineralization can lead ...
Experimental Study And Modeling Of Smart Loss Circulation Materials; Advantages And Promises, 2017 Louisiana State University and Agricultural and Mechanical College
Experimental Study And Modeling Of Smart Loss Circulation Materials; Advantages And Promises, Ahmed Khaled Abdelmaksoud Mansour
LSU Master's Theses
Lost circulation occurs when mud or cement is lost to the formation while drilling. Lost circulation has been a huge problem and may cause heavy financial costs in the form of lost rig time, mud fluid and in severe cases, well blowout with serious environmental and safety consequences. Despite extensive advances in the last couple of decades, lost circulation materials used today still have disadvantages such as damaging production zones, plugging drilling tools or failing to seal the fractures. Here, we propose a new class of smart expandable lost circulation material (LCM) to remotely control the expanding force and functionality ...
Surface Tension, Interfacial Tension And Phase Behavior: Interactions Of Surfactant/Polymer Solutions With Crude Oil, Michael A. Steinerd, Jaeyub Chung, Bryan W. Boudouris, Nathan C. Schultheiss, Elias I. Franses
The Summer Undergraduate Research Fellowship (SURF) Symposium
Advanced oil recovery techniques, beyond primary and secondary recovery, are required in order to produce additional oil in existing reservoir rock. Here, we evaluated a combination of polymer and surfactant aqueous solutions, in order to generate a working fluid capable of achieving high-performance enhanced oil recovery (EOR). In this recovery process, surfactant is added to the water flooding mixture in order to lower the interfacial tension between the oil and the water. If the interfacial tension can be decreased by ~1,000-fold, then the aqueous solution can mobilize and displace the oil. Moreover, a polymer is added to the aqueous ...
Membrane Surface Engineering For Biochemical Applications, 2017 University of Arkansas, Fayetteville
Membrane Surface Engineering For Biochemical Applications, Anh T. Vu
Theses and Dissertations
Synthetic membranes have been frequently used for many fields, such as, the food and beverage, biopharmaceutical, and biofuel industries. In the beer industry, microfiltration frequently suffers from fouling due to the interaction between different species. It is shown that polyphenols can form cross-links with protein molecules, forming insoluble aggregates. However, by adding an optimal amount of polysaccharides these aggregates can be disrupted thus reducing fouling by the aggregates. Confocal laser scanning microscopy (CLSM) is a powerful technique to locate the foulants inside the wet membrane in order to understand more about the behavior of fouling in microfiltration.
Membrane surface modification ...
Comparison Of Intrusive And Non-Intrusive Methods For Corrosion Monitoring Of Fuel Processing Systems, 2017 California Polytechnic State University, San Luis Obispo
Comparison Of Intrusive And Non-Intrusive Methods For Corrosion Monitoring Of Fuel Processing Systems, Armando Jacob Espinoza, Thomas Conner Field
This presentation contains an assessment of the best overall corrosion monitoring device, intrusive or non-intrusive, for use in the petrochemical industry. Corrosion in the petrochemical industry is a large issue because it causes a deterioration of pipe integrity in fuel processing systems. A reduction of pipe wall integrity due to corrosion could result in a leak or an explosion of fuel processing lines since those systems function at high pressures. The use of corrosion monitoring systems in the petrochemical industry helps to detect early signs of corrosion prior to failure so that proper maintenance can be performed to prevent catastrophe ...

Flash Gas Management Analysis, Joshua T. Knight, Tayln M. Costello
Honors Theses AY 16/17
The petroleum industry is always evolving and improving, both in profitability and environmental responsibility. Jonah Energy in Pinedale, Wyoming is a on the cutting edge of that innovation. As a senior design team, they have asked us to specifically investigate the economic viability of different flash gas management solutions.
The first option is to install a Vapor Recovery Unit (VRU). This unit routes the flash gas through a scrubber for dehydration, through a compressor for pressurization and then into the sales line. This is both economically and environmentally more beneficial than flaring the gas. However, certain flash gas rates are ...

Reservoir simulation study using ECLIPSE 100 was used to study the different development options of surfactant ...
Modeling The Effect Of Methane Vs. Carbon Dioxide Injection On Oil Recovery: Case Study: The East Vacuum Grayburg-San Andres Unit, Lea County, New Mexico, Charles Ohalekwu
Graduate Theses & Non-Theses
This project aims to determine if methane (CH4) injection is more effective and economical than carbon dioxide (CO2) injection in a conventional dolomite reservoir by using the East Vacuum Grayburg-San Andres Unit (EVGSAU), Lea County, New Mexico as a model. This was done by simulating a CH4 and CO2 injection system and estimating the economics for each. CH4 injection has not been done at the EVGSAU, however CO2 has been used as a method of enhanced oil recovery.
The EVGSAU is located on the eastern side of the Vacuum Field, approximately 15 miles northwest of Hobbs in Lea County, New ...
Removal Of Chlorine From Chlorine-Nitrogen Mixture In A Film Of Liquid Water, 2017 University of Dayton
Removal Of Chlorine From Chlorine-Nitrogen Mixture In A Film Of Liquid Water, Sarwan S. Sandhu
Sarwan S. Sandhu
In industry there are many examples of absorption of a gas with or without chemical reaction in the liquid phase. In physical absorption, a particular gaseous component is removed from a gas mixture due to its larger solubility in the liquid phase solvent. The removal of butane and pentane from a refinery gas mixture by a heavy oil in the liquid phase is an example of physical absorption. In absorption with chemical reaction, the gaseous component to be removed transfers across the gas-liquid interface due to a difference in the bulk chemical potentials or concentrations in the two phases. The ...

Effects Of Corrosion Inhibitor On The Corrosion Behavior Of Low Carbon Steel In Co2 Environment, Michael Harris
Honors Research Projects
The effectiveness of Benzalkonium chloride (C14) as a corrosion inhibitor for mild steel in an aqueous CO2 environment was studied for dual use. It is a known biocide and currently untested corrosion inhibitor. Potentiodynamic polarization was used to determine the anodic and cathodic reaction kinetics through analysis of the potentiodynamic curves and the corrosion current densities. Electrochemical impedance spectroscopy (EIS) was utilized to analyze the surface characteristics through analysis of the Nyquist and Bode plots. C1010 and C1018 mild steel were tested in a 200mL jacketed Gamery cell, and purged with CO2 (99.9%). Temperature effects were studied ...
Detecting Overpressure Zones By Using Model Based Inversion In Kupe Field, New Zealand, 2017 Michigan Technological University
Detecting Overpressure Zones By Using Model Based Inversion In Kupe Field, New Zealand, Timucin Cakir
Dissertations, Master's Theses and Master's Reports
Overpressure is a significant parameter during a drilling process in oil exploration. This phenomenon happens when pore pressure exceeds the limit of hydrostatic pressure in a formation and causes drastic hazards such as blow outs while drilling. This thesis focuses on the determination of possible overpressure areas and studies at three wells in Kupe Field, which is considered to be a natural-gas field in Taranaki Basin. In an effort to identify potential overpressure zones at the Kupe Field, acoustic impedance responses of 3D seismic data for three wells, along with their well log responses were evaluated.
Seismic inversion plays an ...
