Contribution of Rock Physics Laboratory Tests and Modelling to Improving Uplift Estimates
(Chapter, 2018)Most currently applied procedures for uplift estimation rely on assumptions that porosity and seismic / log measured velocity are unaltered by the uplift process. Laboratory experiments have been performed with synthetic ... -
Controller Design and Control Structure Analysis for a Novel Oil–Water Multi-Pipe Separator
(Journal article; Peer reviewed, 2019)To enable more efficient production of hydrocarbons on the seabed in waters where traditional separator equipment is infeasible, the offshore oil and gas industry is leaning towards more compact separation equipment. A ... -
Cooling aerosols and changes in albedo counteract warming from CO2 and black carbon from forest bioenergy in Norway
(Journal article; Peer reviewed, 2018)Climate impacts of forest bioenergy result from a multitude of warming and cooling effects and vary by location and technology. While past bioenergy studies have analysed a limited number of climate-altering pollutants and ... -
A core flood and microfluidics investigation of nanocellulose as a chemical additive to water flooding for EOR
(Peer reviewed; Journal article, 2020)Cellulose nanocrystals (CNCs) and 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (T-CNFs) were tested as enhanced oil recovery (EOR) agents through core floods and microfluidic experiments. ... -
Correlating Recovery Factors with Measures of Reservoir Heterogeneity
(Master thesis, 2018)Field scale reservoir simulations are computationally intensive, and therefore also time consuming. This thesis focuses on the development and evaluation of computationally easy measures of reservoir heterogeneity, by ... -

Cost Optimization Strategies and Methodologies for Drilling CCS Injection Wells
(Master thesis, 2023)Det nåværende globale kostnaden for karbonfangst- og lagringsteknologi (CCS) er på omtrent 600 dollar per tonn lagret CO2. Med et årlig utslipp på omtrent 431 millioner tonn, utgjør den samlede globale kostnaden for å lagre ... -
Coupled reservoir-network simulations with ESP's and multiphase pump built in
(Master thesis, 2016)The present project is focused on evaluating dual boosting (production with seabed boosting and electric submersible pumps, ESPs, simultaneously) as an alternative to improve total oil production rate of subsea fields. ... -
Creep and Consolidation in Pierre Shale - Identification of how time-dependent effects are influenced by alteration in pore fluid pH and changes in stress conditions
(Master thesis, 2016)The Petroleum Safety Authority of Norway (PSA) has now acknowledged the use of shale as an annular barrier for permanent plug and abandonment (PP&A) operations in the oil industry. Shale can exhibit a natural self-sealing ... -

Cruise Report: Mid-Atlantic Ridge 44N August-September 2017
(NTNU Cruise reports;, Research report, 2017)This cruise is a result of successful collaboration between NTNU Ocean pilot project Deep Sea Mining and Ocean Infinity, ocean exploration company. It took place at the Northern part of Mid-Atlantic ridge in August - ... -
Cryptic Variations of Olivene and Clinopyroxene in the RF-4 Drill-Core: - A geochemical study of the Reinfjord Ultramafic Complex, Norway.
(Master thesis, 2016)The aim of the study is to estimate the cryptic variations of whole-rock samples as well as in olivine and clinopyroxene below and throughout the Ni-Cu reefs in the RF-4 drill-core and to study the relationship between the ... -
Crystallization and uplift path of late Variscan granites evidenced by quartz chemistry and fluid inclusions: Example from the Land's End granite, SW England
(Peer reviewed; Journal article, 2016)The megacrystic, coarse-grained granite of the Land’s End granitic complex, SW England, has been investigated by analyzing fluid inclusions, trace elements, and cathodoluminescence textures of quartz. By applying the TitaniQ ... -
Cuttings Bed Erosion
(Master thesis, 2017)The growth of cuttings beds in horizontal and highly inclined wells in the wellbore is one of the main problems in oil and gas industry. The main purpose of this project is to find the flow velocity at which the erosion ... -
Cuttings Bed Erosion in Horizontal Wells
(Master thesis, 2016)Many of the time consuming and economically demanding drilling problems faced today can be tracked back to poor hole cleaning, even more so when drilling through highly inclined sections. Improved hole cleaning operations ... -
Cuttings Transport in Inclined Sections
(Master thesis, 2017)Mud rheology is a key parameter in hole cleaning efficiency. Field data suggests that oil-based drilling fluids perform better compared to water based drilling fluids in the field, even with identical rheological properties, ... -
Cyclic fatigue in unlined hydro tunnels caused by pressure transients
(Peer reviewed; Journal article, 2021)Regulated hydropower is currently the most capable load balancing technology for the future renewable energy system which will be characterized by a large share of unregulated energy from solar and wind power. Increased ... -
Cyclic oedometer swelling tests on rocks from North-Central Luzon, Philippines
(Chapter, 2020)Tunnels passing through swelling rocks are subjected to stability problems as moisture changes affect the material properties of the rocks. The drying out process during construction may cause local contraction stresses ... -
Cyclic Same-Well Enhanced Oil Recovery - Gas EOR Assessment for a Horizontal Multi-Fractured Well
