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 ... -
Sustainable Flexibility Metrics : Measuring economic flexibility relative to environmental and structural sustainability

Svaddenipun, Rjukan: Stability analysis of potentially unstable mountainside
(Master thesis, 2010)The steep topography of Norway has caused numerous of large-scale rock slope failures with fatal consequences and the Norwegian Geological Survey landslide database covers over 3000 landslide events. Large-scale slope ... -
The Svalbard Carboniferous to Cenozoic Composite Tectono-Stratigraphic Element
(Journal article; Peer reviewed, 2022)The Svalbard Composite Tectono-Stratigraphic Element is located on the north-western corner of the Barents Shelf and comprises a Carboniferous to Pleistocene sedimentary succession. Due to Cenozoic uplift the succession ... -
Svalbard Composite Tectono-Sedimentary Element, Barents Sea
(Peer reviewed; Journal article, 2023)The Svalbard Composite Tectono-Sedimentary Element (SCTSE) is located on the northwestern corner of the Barents Shelf and comprises a Carboniferous–Pleistocene sedimentary succession. Due to Cenozoic uplift, the succession ... -
The Sveconorwegian orogeny – reamalgamation of the fragmented southwestern margin of Fennoscandia
(Peer reviewed; Journal article, 2020)The Sveconorwegian orogeny encompasses magmatic, metamorphic and deformational events between ca. 1140 and 920 Ma at the southwestern margin of Fennoscandia. In recent years, the tectonic setting of this nearly 200 Myr-long ... -

Swelling pressures of some rocks using different test procedures
(Chapter, 2018)There are no clearly defined rules for the investigation procedures of swelling rocks. Difficulties are generally met for characterization and testing of swelling rocks and for prediction of the response to tunnel excavation. ... -
Synchronization of networked oscillators under nonlinear integral coupling
(Journal article; Peer reviewed, 2018)In this paper, we consider synchronization of dynamical systems interconnected via nonlinear integral coupling. Integral coupling allows one to achieve synchronization with lower interaction levels (coupling gains) than ... -
Synkinematic intrusion of granitoid sheets, with implications for molybdenite deposits in the Knaben Zone - Sirdal Magmatic Belt, SW Norway
(Master thesis, 2015)The Knaben Zone represents a N-S-elongated zone with abundant xenolith screens and molybdenite deposits within the late Mesoproterozoic Sirdal Magmatic Belt (SMB) batholith in the Sveconorwegian orogen, in SW Norway. The ... -
Syntactic Foam as Mitigation against Thermally Induced Trapped Annulus Pressures on the Linnorm field
(Master thesis, 2013)An investigation on the feasibility of a crushable foamwrap productfor mitigation of annulus pressure buildup on the Linnorm projecthave been performed. Several different aspects of this technology havebeen investigated, ... -
System and method for estimation of drill cuttings concentration in a borehole
(Master thesis, 2015)Faster and cheaper wells are important to increase the recovery factor from producing fields and for making marginal fields profitable. Hole cleaning is a time consuming non-productive operation which increases well cost. ... -
System Design for the Next Generation Subsea IMR Vehicles
(Doctoral theses at NTNU;2018:196, Doctoral thesis, 2018)This thesis is about how to unlock the full potential of unmanned underwater vehicles to save cost and increase quality in inspection maintenance and repair (IMR) services for subsea petroleum extraction equipment. Today ... -
