Subsea Well Intervention in the North Sea - Learning from Mistakes and Experience
(Master thesis, 2012)BP Norway is well versed in well intervention from fixed platforms. The present Skarv field development will however require future subsea well interventions to take place from different floating vessels. BP has extensive ... -
Subsea Wellhead Life-Cycle-Fatigue Analysis and the Role of Well Temperature
(Journal article; Peer reviewed, 2018)Pushing the frontier of oil exploration and production into more-challenging environments and more-frequent interventions and workover operations in subsea wells has led to an increased focus on the structural integrity ... -
Subsurface structure and hydrothermal fluid circulation at the Mohns mid-ocean ridge: a multi-geophysical investigation
(Doctoral theses at NTNU;2020:283, Doctoral thesis, 2020)Despite the small size of submarine hydrothermal vents exposed on seafloor, the extent and geological significance of hydrothermal systems span over distance of kilometers both laterally and in depth. However, due to ... -
Suitability of Thermosyphon as a Ground Freezing Technology in Longyearbyen
(Master thesis, 2022)Nedkjøling av grunnen er i mange tilfeller nødvendig ved bygging av infrastruktur i arktiske områder for å unngå tining av permafrost. Tining av løsmasser og berg reduserer materialets trykkfasthet, som igjen kan gi setninger ... -

Sunndalsøra groundwater works: Water quality assessments
(Master thesis, 2010)factors controlling groundwater quality is of great importance in the context of exploiting and supplying groundwater of good quality for public use. Groundwater quality is conditioned by aspects of geological and hydrological ... -
Superstructure optimization of subsea processing layouts
(Journal article; Peer reviewed, 2023)As the oil and gas industry expands the use of subsea processing, the complexity of subsea layouts increases, making manual design processes cumbersome and suboptimal. Here we propose a method to support subsea field design ... -
Supradetachment to rift basin transition recorded in continental to marine deposition; Paleogene Bandar Jissah Basin, NE Oman
(Peer reviewed; Journal article, 2020)A transition from supradetachment to rift basin signature is recorded in the ~1,500 m thick succession of continental to shallow marine conglomerates, mixed carbonate‐siliciclastic shallow marine sediments and carbonate ... -
Surface roughness in bubble attachment and flotation of highly hydrophobic solids in presence of frother – experiment and simulations
(Journal article; Peer reviewed, 2017)In this paper, the kinetic of the three-phase contact (TPC) formation and the flotation recovery of highly hydrophobic solids with different surface roughness were studied in pure water and aqueous solutions of n-octanol. ... -
Surface Seismic While Drilling - A new method for relief well drilling
(Master thesis, 2013)The first relief wells emerged out of necessity, and have since been shaped by several disastrous events throughout the 20th and 21th century. The modern relief well shows little resemblance to the first relief wells that ... -
Surface volume control through continuous surveillance of drilling data
(Master thesis, 2017)When a new well is being drilled, volume control should be among the most important focus areas for the drilling crew. In every drilling operation, pressures exerted from the formations need to be controlled and overbalance ... -
Surface-Charge Alteration at the Carbonate/Brine Interface During Single-Well Chemical-Tracer Tests: Surface-Complexation Model
(Journal article; Peer reviewed, 2018)Water chemistry has been shown to affect oil recovery by affecting surface charge and rock dissolution. The single-well chemical-tracer (SWCT) test is a field method to measure residual oil saturation (Sor), in which ... -
Surfactant Enhanced Oil Recovery in Fractured Reservoirs: Simulation study of surfactant spontaneous and dynamic imbibition
(Doctoral theses at NTNU;2019:387, Doctoral thesis, 2019)Water flooding has poor performance in fractured reservoirs with mixed- or oil-wet wettability. Surfactant could be used to improve oil recovery by changing wettability to more water-wet or reducing water/oil interfacial ... -
Surge and Swab Pressure Calculation: Calculation of Surge and Swab Pressure Changes in Laminar and Turbulent Flow While Circulating Mud and Pumping
(Master thesis, 2014)Pressure changes due to Surge and Swabs has in many years been a big concern in the industry. If the pressure changes become too high, the formation can fracture, and formation influx can lead to a kick. In worst case ... -
Surge and Swab Simulations
(Master thesis, 2019)Det er nye tider i energisektoren og det er stort fokus på optimal olje- og gassutvinning. Samtidig som verden ønsker å bevege seg i en miljøvennligretning mot mindre utslipp, er vi i stor grad fremdeles avhengige av olje ... -
A Survey on the Application of Machine Learning and Metaheuristic Algorithms for Intelligent Proxy Modeling in Reservoir Simulation
(Peer reviewed; Journal article, 2022)Machine Learning (ML) has demonstrated its immense contribution to reservoir engineering, particularly reservoir simulation. The coupling of ML and metaheuristic algorithms illustrates huge potential for application in ... -
Suspended Sediment Source and Transport Mechanisms in a Himalayan River
(Journal article; Peer reviewed, 2024)The process of estimating sediment load has been a daunting issue in hydraulics and the water resource field. Several methods exist for predicting the sediment load in a catchment or river, but the majority of these methods ... -
