Application of DFT in iron sulfide scale removal from oil and gas wells
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ... -
Exploration of Carbonate Aggregates in Road Construction using Ultrasonic and Artificial Intelligence Approaches
( Qatar University Press , 2023 , Conference Paper)The COVID-19 pandemic has significantly impacted the construction sector, which is highly sensitive to economic cycles. In order to boost value and efficiency in this sector, the use of innovative exploration technologies ... -
Grouping minimum REV of porosity and tortuosity based on descriptors of sand grains
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)In sandy reservoirs, selecting a representative elementary volume (REV) for the pore scale, is essential for predictive upscaling toward the reservoir scale. The porosity and tortuosity of a sand media are used for REV ... -
Hydrate surface area measurements during dissociation using dynamic 3d synchrotron computed tomography
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Availability of natural hydrates and ongoing rise in demand for energy, motivated researchers to consider hydrates as a potential energy source. Prior to gas production operations from hydrate-bearing sediments, hydrate ... -
Linking depositional environments and diagenetic processes to porosity evolution and destruction in the Arab Formation reservoirs, Offshore oilfields of Qatar
( Qatar University Press , 2020 , Poster)Introduction: The Jurassic Arab Formation is the main oil reservoir in Qatar. The Formation consists of a succession of limestone, dolomite, and anhydrite. Materials and Methods: A multi-proxy approach has been used to ... -
Microporosity evolution and destruction in the Jurassic Arab D reservoir, Qatar
( Institute for Ionics , 2023 , Article)Core samples were collected from three wells, one onshore and two offshore, from Qatar’s Upper Jurassic Arab D reservoir. The samples were subjected to multiproxy petrographic and chemical analyses to identify their micro- ... -
Pore networks to characterize formation damage due to fines at varied confinement and sand shape
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Carbon sequestration in geological formations is in demand for many applications, especially energy production from hydrates. During gas production in a sandy hydrate reservoir, two phase flow and changes in confinement ... -
Pore-scale mechanisms associated with permeability impairment in porous media: A micromodel study
( European Association of Geoscientists and Engineers, EAGE , 2019 , Conference Paper)Recently, researchers are attracted towards the gas production from hydrate bearing sediments considering its abundance in marine continental margins and persisting demand for alternate energy. Dissociation of hydrate into ... -
Synthesis and infrared spectra of alkaline earth metal carbonates formed by the reaction of metal salts with urea at high temperature
( Indian Academy of Sciences , 2004 , Article)The metal carbonate, MCO3 (M = Ca, Sr and Ba), was synthesized by a novel method of reacting aqueous solution of each of Ca2+, Sr2+ and Ba2+ salts with urea at high temperature, ∼ 80°C. The reaction products were characterized ... -
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
( Royal Society of Chemistry , 2021 , Article)Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form ...
