Characterization of graphene nano platelets reinforced wellbore cement
Massion, Cody (2021-12)To improve the mechanical performance of wellbore cement under subsurface environments, graphene nanoplatelets (GNPs) are added in various percentages to Class-H cement slurry. Microstructural characterization of cement ... -
Impact of rock lithology and microstructural properties on proppant embedment and fracture conductivity: A case study of the Caney Shale, Southern Oklahoma, USA
Katende, Allan (2022-12)A key feature of shale reservoirs is their low level of permeability. As a means of producing these reservoirs in a cost-effective manner, there is a requirement to create hydraulic fractures with highest level of conductivity, ... -
Laboratory evaluations on the mechanical impact of nanoparticle additives in a heavy wellbore cement
Ritchie, Mark Colten (2019-12)Ever since its inception, the oil and gas industry has taken a short term approach to maintaining zonal isolation and permeant plugging using wellbore cements. Continuous changes to their environment over the life of a ... -
Material characterization of graphene enhanced Class-H cement under thermal cyclic conditions
Jupudi, Havila (2022-12)Geothermal heat harvesting is the process of extracting heat from the earth’s subsurface where it is trapped below the diverse rock formations to be converted into usable energy. Cementing of the drilled wells requires the ... -
Microstructural and mechanical characterization of zeolite enhanced wellbore cement for plugging and abandonment
Vissa, Sai Vamsi Krishna (2021-12)Major technological improvements have been seen in the drilling and completions of oil and gas wellbores, to enable safer exploration and production of fossil fuels. On the other hand, plugging and abandonment (P&A) of ... -
Performance based testing for air entrainment and total heat of reclaimed fly ash
Emerson, Loren (2021-07)As coal combustion energy plants are being converted to natural gas, the tons of fly ash produced in the United States has dramatically decreased. The current demand in fly ash supply can be mitigated with the introduction ... -
Quantifying the efficiency and quality of air void distributions in concrete
Becker, Hope Hall (2022-05)This work establishes new ways to measure and examine the air bubble distribution within concrete. This is important to provide freeze thaw durability and resistance to oxychloride formation. These bubbles decrease the ...
