Development of Real-Time Smart Data Analytic Tools for Monitoring and Optimum Operation of MGT Systems
(PhD Theses;762, Doctoral thesis, 2024)In the evolving energy landscape, a shift away from traditional centralized power models is underway. Distributed energy generation (DEG) takes the spotlight, enabling consumers to utilize a tailored mix of energy sources. ... -
Drilling Fluid Additives for Wellbore Strengthening and Reservoir Protection
(PhD Theses;726, Doctoral thesis, 2023)The objective of the research was to optimise drilling fluid additives for wellbore strengthening, preventing lost circulation and avoiding drilling fluid induced formation damage. Industry standard testing, such as HTHP ... -
Impact of Wettability on Rock Mechanics and Oil Recovery: A Comparative Study on Different Outcrop Chalks
(PhD thesis UiS;502, Doctoral thesis, 2020-04)Chalk reservoirs are highly fractured and are known for their remarkable storage capacity as a reservoir rock for the petroleum industry. Chalk is a sedimentary carbonate rock primarily made up of calcium carbonate (calcite, ... -
Mathematical Modelling of the Drilling Process for Real-time Applications in Drilling Simulation, Interpretation and Assistance
(PhD thesis UiS;, no.;506, Doctoral thesis, 2019)For the last thirty years, mathematical modelling has been used to develop software solutions that support drilling engineering activities at the planning stage of drilling operations. But it is only for the last decade ... -
Ostwald ripening of trapped gas bubbles in porous media : A pore-scale perspective
(PhD thesis UiS;747, Doctoral thesis, 2024)Ostwald ripening of gas bubbles is a thermodynamic process for mass transfer, which is significant for both foam-enhanced oil recovery and underground gas storage. During recovery, it can impact the macroscopic efficiency. ... -
Particle Settling in shear thinning non-Newtonian drilling fluids : Effect of oscillatory motion
(PhD thesis UiS;537, Doctoral thesis, 2020-09)When drilling fluids circulate through the well and during the solids control operations, they are exposed to vibrations and oscillations of different frequencies and amplitudes. The secondary flow structures in oscillatory ... -
Transition-metal-mediated electrocatalytic CO2 reduction: from nanoparticles to single-atom catalysts
(PhD Theses;709, Doctoral thesis, 2023)With the rapid development of the global economy, energy crisis and environment issues have become increasingly prominent. Carbon dioxide (CO2) is a primary greenhouse gas (CHG), while it could also be a valuable carbon ...
