Effect of buoyancy and inertia on viscoplastic fluid-fluid displacements in a regular and an irregular eccentric annulus
(Peer reviewed; Journal article, 2020-09)Casing strings and liners are important subsurface structural components in petroleum and in geothermal wells. After the casing string has been run in hole, it is cemented to the formation by pumping a sequence of spacer ... -
Effect of Calcium Expansive Additives on the Performance of Granite-Based Geopolymers for Zonal Isolation in Oil and Gas Wells
(Peer reviewed; Journal article, 2023)Geopolymers have emerged as a promising alternative to Portland cement for oil and gas wells. Achieving effective zonal isolation by use of geopolymers may require controlling their expansion. This study investigates the ... -
The Effect of Climate on the Solar Radiation Components on Building Skins and Building Integrated Photovoltaics (BIPV) Materials
(Peer reviewed; Journal article, 2021-03)The business model of building-integrated photovoltaics (BIPV) is developing expeditiously and BIPV will soon be recognised as a building envelope material for the entire building skins, among other alternatives such as ... -
The Effect of CO2 Curing on Cement-Based Materials
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-07-15)Early carbonation curing of concrete elements has been shown to be a promising sustainable technology for CO2 capture and utilization, which would be beneficial for the environment. It has been found that carbonation curing ... -
Effect of Colloidal Transport on CO2 Injectivity
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Climate change is a long term change in weather due to Earth process, volcanic activity and change concentration of greenhouse gases such as carbon dioxide (CO2) in the atmosphere. CO2 is generated mainly from industrial ... -
Effect of core cleaning solvents on wettability restoration and oil recovery by spontaneous imbibition in surface reactive, low permeable limestone reservoir cores
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The success of oil recovery, by water flooding, in naturally fractured, low permeable limestone reservoirs strictly depends on imbibition of injected water into the reservoir matrix block. Prerequisite of imbibition process ... -
Effect of crude oil adsorption and asphaltene precipitation on sandstone wettability
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Wettability is an important property for oil recovery. It affects capillary pressure and controls fluids, location, and flow in the reservoir. By an increase in capillary pressure (due to increased water wetness), previously ... -
The Effect of Different Drilling Fluids on Mechanical Friction
(Peer reviewed; Journal article, 2017)A very important aspect in highly inclined wellbores is the mechanical friction. For extended reach drilling (ERD) and through tubing extended reach drilling (TTERD) this can be a limiting factor. Friction caused by the ... -
