Enhanced multiscale restriction-smoothed basis (MsRSB) preconditioning with applications to porous media flow and geomechanics
(Peer reviewed; Journal article, 2021)A novel method to enable application of the Multiscale Restricted Smoothed Basis (MsRSB) method to non M-matrices is presented. The original MsRSB method is enhanced with a filtering strategy enforcing M-matrix properties ... -
Enhanced nucleation and precipitation hardening in Al-Mg-Si(-Cu) alloys with minor Cd additions
(Peer reviewed; Journal article, 2020)This work reports a novel effect of impurity element Cd on enhancing the precipitation kinetics and increasing the peak hardness of Al–Mg–Si(–Cu) alloys during artificial ageing. It is found that the number density of age ... -
Enhanced Oil Recovery - Wisting Development
(Master thesis, 2018)The average oil recovery on the Norwegian Continental Shelf is 47% (NPD 2017b). Until today, most of the oil and gas fields at the Norwegian Continental Shelf have been produced with pressure depletion or gas/water injection. ... -
Enhanced Oil Recovery by Low Salinity Surfactant: Effect of Ions on Core and Pore Scales
(Doctoral theses at NTNU;2016:211, Doctoral thesis, 2016)Enhanced oil recovery (EOR) by surfactants is a well-established method in the petroleum industry. In a surfactant flooding, oil is mobilized and recovered by reduction of the interfacial tension (IFT) between oil and water ... -
Enhanced Oil Recovery By Surfactant and Brine Flooding
(Master thesis, 2010)It is well known to the art of oil recovery technique that only a fraction of the original oil in place can be recovery by primary recovery method. This method allows oil to flow to the surface by means of natural energy ... -
ENHANCED OIL RECOVERY FOR NORNE FIELD (STATOIL) C-SEGMENT USING ALKALINE-SURFACTANT-POLYMER FLOODING
(Master thesis, 2012)A great percentage of oil is observed to be left in the reservoir after the traditional primary and secondary recovery methods. This oil is described as immobile oil. Alkaline-Surfactants are chemicals used to reduce the ... -
Enhanced Oil Recovery for Norne Field E-Segment using Alkaline Surfactant-Polymer Flooding
(Master thesis, 2019)In life of the oil field, reservoir pressure tends to decrease with the development of the production. The use of primary and secondary recovery techniques enables recovery of only 35-50% of the oil in the reservoir. That ... -
Enhanced oil recovery for Norne Field's E-segment using surfactant flooding
(Master thesis, 2010)About 60% of oil still lays trapped in the reservoir even after primary and secondary recovery processes have been completed. This trapped oil could be residual or by-passed oil. Residual oil occurs as a result of high ... -
Enhanced Oil Recovery from Oil-Wet Carbonate Rock by Spontaneous Imbibition of Aqueous Surfactant Solutions.
(Dr.ingeniøravhandling, 0809-103X; 2001:81, Doctoral thesis, 2001) -
Enhanced oil recovery using silica nanoparticles: An experimental evaluation of oil production, recovery mechanisms and nanofluid stability
(Doctoral theses at NTNU;2017:328, Doctoral thesis, 2017) -
Enhanced Option Pricing Using Deep Learning: A Time-Series Approach with a Combined LSTM-MLP Model
(Master thesis, 2023)Denne artikkelen presenterer en dyplæringstilnærming til opsjonsprising som integrerer et long short-term memory (LSTM) nettverk med et multi-layer perceptron (MLP) netverk for å danne en kombinert LSTM-MLP modell. Den ... -
Enhanced path sampling using subtrajectory Monte Carlo moves
(Journal article, 2023)Path sampling allows the study of rare events, such as chemical reactions, nucleation, and protein folding, via a Monte Carlo (MC) exploration in path space. Instead of configuration points, this method samples short ... -
Enhanced permafrost creep model– user manual and documentation
(Research report, 2016)The mechanical behavior of frozen soils is one of the challenging topics in the field of geotechnical engineering. The behavior of frozen soils is strongly affected by the amount of ice, while on the other hand, the amount ... -
Enhanced Power Capability of Generator Units for Increased Operational Security using NMPC
(Journal article; Peer reviewed, 2019)The ever-increasing penetration of intermittent energy sources introduces new demanding operating regimes for the bulk power generation in the power grid. During a worst-case power system disturbance scenario, the generator ... -
