Blå Hydrogen Produksjon
(Bachelor thesis, 2021)Hydrogen as a chemical energy carrier for green energy will play an important role in the reduction of CO2 emissions. Today 76% of the world’s hydrogen production comes from fossil fuels, from natural gas and coal without ... -
Blocking of fracture by Laponite/HPAM gels: Experiments and simulations
(Master thesis, 2021)Water production is the primary obstacle for oil recovery with water injection from heterogeneous reservoirs with high-permeability streaks and fractures. The practical approach to solve the adverse effects of water flooding ... -
Blowout Flow Rate Modelling
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)A blowout represent one of the major concerns associated with drilling, completion, maintenance and production of an oil field. Calculation of blowout rate is commonly one of the first steps in an Environmental Risk Analysis, ... -
Bonding Mechanism of Zonal Isolation Materials to Clean and Rusted Casing
(Peer reviewed; Journal article, 2022)In oil and gas and geothermal well construction, a cementitious material is pumped in the wellbore to provide zonal isolation and support the casing during the life cycle of the well. Thus, the cementitious barrier materials ... -
Boundary Condition Treatment in a Transient Flow Model
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-14)Transient flow modelling used for hydraulic calculations and well control evaluations is a vital part to the safety in the industry to properly prepare and build correct procedures when constructing wells. Modeling liquid ... -
Breaking Scaling Relations for Highly Efficient Electroreduction of CO2 to CO on Atomically Dispersed Heteronuclear Dual-Atom Catalyst
(Peer reviewed; Journal article, 2023)Conversion of CO2 into value-added products by electrocatalysis provides a promising way to mitigate energy and environmental problems. However, it is greatly limited by the scaling relationship between the adsorption ... -
Bridging performances of lost circulation materials (LC-LUBE and mica) and their blending in 80/20 and 60/40 oil-based drilling fluids
(Peer reviewed; Journal article, 2022)In drilling wells, lost circulation, barite sagging, shale swelling, and formation damage are critical problems for the industry. These problems can be controlled by designing appropriate drilling fluids and lost circulation ... -
Can methane pyrolysis based hydrogen production lead to the decarbonisation of iron and steel industry ?
(Peer reviewed; Journal article, 2021)Decarbonisation of the iron and steel industry would require the use of innovative low-carbon production technologies. Use of 100% hydrogen in a shaft furnace (SF) to reduce iron ore has the potential to reduce emissions ... -
