Surface Complexation Modelling of Wettability Alteration during Carbonated Water Flooding
(Master thesis, 2021)Within the context of global warming, Carbon Dioxide (CO2) capture and its utilization in oil recovery are seen as one of the majority methods to decrease Greenhouse Gas (GHG) emissions over the next few decades. CO2 ... -
Surface Complexation Modelling of Wettability Alteration during Carbonated Water Flooding
(Peer reviewed; Journal article, 2022)CO2 capture and utilization is an effective tool in reducing greenhouse gas emissions and hence, combating global warming. In the present study, surface complexation modeling (SCM) with the geochemistry solver, PHREEQ-C, ... -
Surface Forces Apparatus Measurements of Interactions between Rough and Reactive Calcite Surfaces
(Journal article; Peer reviewed, 2018-05)Nm-range forces acting between calcite surfaces in water affect macroscopic properties of carbonate rocks and calcite-based granular materials, and are significantly influenced by calcite surface recrystallization. We ... -
Surface Tension Measurement by Maximum Bubble Pressure Method
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)The principal objective of the present work is to measure the surface tension of liquids by the use of a method that it is not commonly found in books but it is based on very basic principles of Fluid Mechanics. This thesis ... -
Synthesis and Development of One-part Rock-based Geopolymers for Well Cementing Applications
(PhD Theses UiS;717, Doctoral thesis, 2023)A one-part or Just Add Water (JAW) geopolymer system is an environmental- and user-friendly alternative to Ordinary Portland Cement (OPC) and conventional geopolymers. It helps with producing lower CO2 emissions avoiding ... -
Synthesis, characterization, and activity of bimetallic Ni-Fe hydrotalcite-derived catalysts in dry reforming of methane
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)The extensive amount of carbon dioxide (CO2) emitted into atmosphere is arguably considered to be the main reason for global climate change due to the greenhouse effect. For decades, considerable efforts have been devoted ... -
