An Experimental Study Of Fractional Wettability Effects On Gas Assisted Gravity Drainage (Gagd), ABDULLAH ABDULRAHMAN A. AL-TAMEEMI 2019 Louisiana State University and Agricultural and Mechanical College

An Experimental Study Of Fractional Wettability Effects On Gas Assisted Gravity Drainage (Gagd), Abdullah Abdulrahman A. Al-Tameemi

LSU Master's Theses

Utilizing the power of nature to solve engineering problems has been a time-honored tradition, for example, using the sunlight as a heat and light source. From this principle, the visionary idea of Gas Assisted Gravity Drainage (GAGD) came. The GAGD process utilizes the natural segregation phenomenon of fluids with different densities in order to produce oil efficiently and economically. Waterflooding processes typically do not recover more than 40% of the original oil in place (OOIP), leaving a vast amount of oil behind. A practical and well-planned enhanced oil recovery (EOR) method is needed. However, to plan a successful project, the ...

Pre-Methylation Of Lignin To Improve Storage Stability Of Oil Produced By Solvent Liquefaction, Jae-Young Kim, Parinaz Hafezi-Sefat, Sarah D. Cady, Ryan G. Smith, Robert C. Brown

Mechanical Engineering Publications

In this study, we methylated hydroxyl groups (phenolic hydroxyl: Phe-OH and aliphatic hydroxyl: Aliph-OH) in soda lignin (SL) prior to solvent liquefaction to improve storage stability of the resulting oil. We investigated two methylating reagents, dimethyl sulfate (DMS) and dimethyl carbonate (DMC), for selective Phe-OH and total hydroxyl group (Phe-OH and Aliph-OH) blocking. Samples of SL, DMS-SL, and DMC-SL were depolymerized into oils under supercritical ethanol (350 °C). Both methylated lignins produced higher amounts of oils and smaller amounts of char compared to untreated SL due to suppressed charring reactions. Oil produced from SL had relatively higher functional group contents ...

Experimental Study On The Influence Of Slickwater On Shale Permeability, Zhonghua Liu, Baojun Bai, Zheyu Zhang, Jing Tang, Shunpeng Zeng, Xiaogang Li

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

There are two diametrically opposite views of the influence of slickwater on shale permeability among scholars at home and abroad. We used the shale outcrops rock samples from the Lower Silurian Longmaxi Formation in Sichuan Basin. The permeability of these dry samples before and after immersion in different solution systems were tested by pulse attenuation method. The experimental results show that the impregnation of different slickwater components and standard salt solution can promote the increase of the permeability of shale samples. The stress sensitivity of shale samples after liquid immersion is medium weak to weak. The sample stress sensitivity is ...


Experimental Evaluation Of Surfactant-Based Nanofluids On Wettability Alteration And Oil Recovery, Mohammad Foad Haeri 2018 Louisiana State University and Agricultural and Mechanical College

Experimental Evaluation Of Surfactant-Based Nanofluids On Wettability Alteration And Oil Recovery, Mohammad Foad Haeri

LSU Doctoral Dissertations

Economic concerns about chemical flooding could be taken as opportunities to develop new cost-effective technologies that lead to high recoveries. Application of surfactants to lower oil-water interfacial tension has never been an economically attractive EOR method due to the high amount of adsorption. However, the use of inexpensive surfactants in low concentrations or combination of diluted surfactants with other low-cost chemicals to change the wettability of the system could play a major role in reducing the residual oil saturation and consequently improving oil recovery. This experimental study aims at investigating the potential of nanoparticles to improve the ability of surfactants ...

Numerical Simulation Study On Miscible Eor Techniques For Improving Oil Recovery In Shale Oil Reservoirs, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai 2018 Missouri University of Science and Technology

Numerical Simulation Study On Miscible Eor Techniques For Improving Oil Recovery In Shale Oil Reservoirs, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Shale formations in North America such as Bakken, Niobrara, and Eagle Ford have huge oil in place, 100—900 billion barrels of oil in Bakken only. However, the predicted primary recovery is still below 10%. Therefore, seeking for techniques to enhance oil recovery in these complex plays is inevitable. Although most of the previous studies in this area recommended that CO2 would be the best EOR technique to improve oil recovery in these formations, pilot tests showed that natural gases performance clearly exceeds CO2 performance in the field scale. In this paper, two different approaches have been integrated ...


Development Strategies For A Fractured, Heavy Oil Reservoir - Results From Numerical Simulations, German Albertovich Abzaletdinov 2018 Louisiana State University and Agricultural and Mechanical College

Development Strategies For A Fractured, Heavy Oil Reservoir - Results From Numerical Simulations, German Albertovich Abzaletdinov

LSU Master's Theses

This research is focused on studying reservoir “N” in the Yarega heavy oilfield (YHOF) for development strategies and production optimization. YHOF is a naturally fractured heavy oil field where only very recently SAGD technology has been introduced. The motivation for this research is derived from the fact that SAGD employed in this field has so far resulted in early steam breakthrough leading to producer abandonment and new drilling, thus increasing costs. This study explores numerically different static and dynamic reservoir characterization models (single porosity versus dual porosity systems), and subsequent pressure-production history matched reservoir simulation for understanding heat and mass ...

"In 2010, the British Petroleum (BP) Deepwater Horizon accident leaked oil into the Gulf of Mexico for 87 days. A fast response method that can seal an oil pipe and stop the release of oil is needed in order to prevent future oil leaks from turning into ecological and financial disasters. Explosives can serve this need.

This research examined how a circular implosive discontinuous explosive lens interacts with a cylindrical surface. The following research was designed to study the applicability of the Method this author developed to predict the peak pressure from multiple shockwaves converging on a centrally located cylinder ...


Experimental And Numerical Investigation Of Liquid-Assisted Gas-Lift Unloading, Renato Peixoto Coutinho 2018 Louisiana State University and Agricultural and Mechanical College

Experimental And Numerical Investigation Of Liquid-Assisted Gas-Lift Unloading, Renato Peixoto Coutinho

LSU Doctoral Dissertations

The case for a unique form of gas-lift unloading, termed “Liquid-Assisted Gas-Lift (LAGL),” is presented. This work demonstrates that the injection of a gas-liquid mixture allows transport of gas to a deep injection point utilizing injection pressure considerably lower than single-phase gas injection. The LAGL is demonstrated in a 2,880 ft deep test well. The test well is kicked-off using an injection pressure that would normally be lower than the pressure for single-point single-phase gas injection at this depth. Experimental results indicate that the LAGL can lower the injection pressure by up to 75%.

This work breaks the LAGL ...

Graduate Theses & Non-Theses

The Frontier Formation in the Powder River Basin has been re-discovered for oil and gas potential with the development of long horizontal wells and multi-stage hydraulic fracturing. Over the last decade, the Upper Cretaceous Wall Creek Member (WCM) of the Frontier Formation has proven to be a successful hydrocarbon-producing target, yet a full understanding of the flow behavior in this complex stratigraphic unit has not been fully achieved.

The fluid and rock properties have uncertainty and are not well defined due to the low permeability rocks. This study aims to describe the fluid flow behaviors of these features and create ...


Pore-Scale Analysis Of Interfacial Instabilities And Impact Of Heterogeneity On Relative Permeability By Lattice Boltzmann Method, Zhipeng Zhu 2018 Louisiana State University and Agricultural and Mechanical College

Pore-Scale Analysis Of Interfacial Instabilities And Impact Of Heterogeneity On Relative Permeability By Lattice Boltzmann Method, Zhipeng Zhu

LSU Master's Theses

Interfacial instabilities occur often during immiscible fluid flow through porous media and their understanding is essential for waterflooding operations or other oil recovery processes. Although many studies including experimental and numerical have been done to reproduce and analyze the interfacial instabilities in porous median, there is still significant knowledge gap in fundamental understanding of these flow instabilities at the pore-scale. In order to better understand the interfacial instabilities phenomenon, the pore-scale simulations are performed. In this study, Lattice Boltzmann Method is used to simulate two different types of interfacial instabilities: viscous fingering and capillary fingering in irregular sphere packs by ...


Magnetic Gradient Drilling, Garrett Lowry Nielsen 2018 Louisiana State University and Agricultural and Mechanical College

Magnetic Gradient Drilling, Garrett Lowry Nielsen

LSU Master's Theses

The drilling industry has always had difficulties with staying within the mud weight window. The problems associated with failure to stay within the mud weight window include uncontrolled influxes and wellbore collapse on the low pressure side of the window, and fluid losses and wellbore damage on the high pressure side of the window. When the risk for getting outside of this mud window becomes too great, casing must be set in order to isolate formations from each other. If too many strings of casing are set, or if the damage from getting out of the mud weight window is ...

Image-Based Modeling Of Flow Through Porous Media: Development Of Multiscale Techniques For The Pore Level, Timothy Wayne Thibodeaux 2018 Louisiana State University and Agricultural and Mechanical College

Image-Based Modeling Of Flow Through Porous Media: Development Of Multiscale Techniques For The Pore Level, Timothy Wayne Thibodeaux

LSU Doctoral Dissertations

Increasingly, imaging technology allows porous media problems to be modeled at microscopic and sub-microscopic levels with finer resolution. However, the physical domain size required to be representative of the media prohibits comprehensive micro-scale simulation. A hybrid or multiscale approach is necessary to overcome this challenge. In this work, a technique was developed for determining the characteristic scales of porous materials, and a multiscale modeling methodology was developed to better understand the interaction/dependence of phenomena occurring at different microscopic scales. The multiscale method couples microscopic simulations at the pore and sub-pore scales. Network modeling is a common pore-scale technique which ...

Understanding Inhibition Of A Biodesulfurization Enzyme To Improve Sulfur Removal From Petroleum, Yue Yu 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 ...
