Sept. 2024: Aqueous Nanobubble Dispersion for Geologic Carbon Sequestration & Enhanced Oil Recovery
Abstract:
Many gaseous species, such as CO2, H2, N2, and light hydrocarbons, exhibit low solubility in water, resulting in small equilibrium concentrations in aqueous fluids (water or brine) across diverse conditions. Leveraging these immiscible gaseous species within aqueous fluids as nanobubble (NB) dispersions presents notable advantages for multiple industries. The current applications of aqueous NB dispersion include agriculture, wastewater treatment, mineral processing, and pharmaceuticals. However, these applications predominantly operate under low-pressure conditions. This webinar explores the transformative potential of high-pressure applications for aqueous NB fluids.

August 2024: Water Production in the Permian: Where is the water coming from?
Просмотров 238Месяц назад
Abstract: Substantial water production associated with shale oil production in unconventional basins presents a challenge for the sustainable development of oil and gas resources. Recent studies have identified the origin and content of water in these unconventional formations such as the Wolfcamp Formation, but little is known regarding the mechanisms and pathways through which water is produc...
June 2024: Applying Maching Learning as a competent Engineer or Geoscientist
Просмотров 5713 месяца назад
Abstract: The subsurface resource industry has a long history of working with large, complex geoscience and engineering datasets. Our community has been dealing with ‘big data’ for decades, which has driven the development and establishment of the geostatistical toolbox. As a result, we are uniquely positioned in the current digital revolution, being further along the path of data-driven workfl...
May 2024: Chemical Methods for Improving Oil Recovery in Shales
Просмотров 3404 месяца назад
Abstract In recent years, hydrocarbon production from shale reservoirs has become a significant contributor to global production, particularly in the United States. The exploration and production of oil from shales are characterized by complex geological structures and unconventional petrophysical properties, which necessitate ongoing research and innovation to make their development economical...
April 2024: Challenges and Opportunities with Geologic Hydrogen
Просмотров 1,7 тыс.5 месяцев назад
Abstract Hydrogen is a carbon-free fuel that produces only water when energy is extracted from it. Decarbonization of our energy supplies can be accomplished in part by including hydrogen as an energy source, particularly in hard-to-abate sectors like steel and cement manufacturing. Nearly all the hydrogen used today is produced by splitting water or methane in chemical plants. However, there a...
February 2024: Pore Occupancy of Gas Hydrate
Просмотров 3537 месяцев назад
Abstract: Methane hydrate deposits are one of the largest fractions of hydrocarbons in the Earth's crust. They are found mainly in ocean sediments, and the configuration of the deposits - at the largest and smallest scales - determines how and when gaseous methane is released. Here using thermodynamic arguments, we show where hydrate is positioned at the pore scale when it is in contact with bo...
January 2024: Microfluidics and Micromodels as EOR Screening Tools
Просмотров 4348 месяцев назад
Abstract Microfluidics allow for investigation and visualization of multiphase flow behavior at small scales. Micromodels are microfluidic porous media that can can tailored geometry and heterogenity. In this work, we investigate enhanced oil recovery mechanisms using microfluidic devices over several scales, from a single channel to core-flood on a chip with hundreds of thousands of pores and ...

December 2023: Gas, Hydrates, and Submarine Landslides
Просмотров 2669 месяцев назад
ABSTRACT: Submarine landslides on passive continental margins remain enigmatic as their triggers and preconditioning factors are poorly understood. Gas hydrates and subsurface gas accumulations are frequently implicated, but little evidence has been collected linking these features to slope failure. We spent 33 days at sea in May and June 2023 collecting 3366 km of 2D seismic data and 80 m of s...

ABSTRACT: The global importance of oil production in the face of increasing demand for energy and its resources cannot be overstated. In addition to traditional brine imbibition into porous matrix domains aimed at displacing substantial amounts of oil towards production wells for maximum oil recovery, eco-friendly and effective oil recovery techniques have been diversely employed. Carbonate res...
September 2023: Scales, Scaling and Scale-Up
Просмотров 625Год назад
Abstract Scaling, the transferring of results at one scale (size)-usually from a small scale to a larger scale-is a large part of engineering practice. Often the practitioner is not aware of doing it, yet scaling up (or the lack thereof) accounts for many inaccurate predictions in flow through porous media processes. This presentation is a discussion of scales encountered in reservoirs, how pet...
August 2023: Combining Sweep and Displacement Efficiency for Reservoir Flooding
Просмотров 754Год назад
Abstract: Almost all conventional reservoirs undergo secondary recovery whether it is water flooding, gas flooding, or some other enhanced oil recovery (EOR) technique. Conceptually, the overall efficiency of the recovery is often broken down into two parts: 1) the displacement efficiency - the fraction of the oil that is displaced by the injected fluid in well swept regions, and 2) the sweep e...
July 2023: Petrophysics of Subsurface Hydrogen Storage
Просмотров 1,6 тыс.Год назад
Abstract: Underground storage of hydrogen has the potential to act as a large battery that can be discharged on weekly, seasonal, or longer timescales. Storage in salt caverns is relatively well understood due to experience with storage of other fluids. Much larger volumes could be stored in saline aquifers or depleted oil and gas fields, but many questions need to be answered before these stor...
June 2023: Geothermal Beyond Power Generation: Direct Air Capture and Geothermal Energy
Просмотров 610Год назад
Abstract Direct air capture (DAC) technologies extract CO2 directly from the atmosphere. There are currently 18 DAC plants operating worldwide, capturing almost 0.01 Mt CO2/year, but they have the potential of scaling up to 60 Mt CO2/year by 2030 (IEA 2023). Two technological approaches are currently being used to capture CO2 from the air. One of them, solid sorbent DAC (S-DAC), operates at amb...
