Closed-Form Solution to the Poromechanics of Deep Arbitrary-Shaped Openings Subjected to Rock Mass Alteration
(Peer reviewed; Journal article, 2020)The aim of this paper is to propose a closed-form solution to the poromechanics problem of stress and pore pressure distribution around noncircular openings at great depth subjected to hydrostatic water pressure and far-field ... -
CO2 Data Share: A Platform for Sharing CO2 Storage Reference Datasets from Demonstration Projects
(Journal article, 2019)Extensive research is ongoing worldwide to build competence and to develop cost-efficient technologies for safe injection and subsurface storage of CO2. Currently, the full potential of academic research is not realized ... -
CO2 Enhanced Oil Recovery in Strong Water-Drive Reservoirs
(Master thesis, 2012)The growing demand for energy has prompted oil companies to increase the production while paying more and more attention to the CO_2 footprint of their activities. To fulfill these requirements CO_2 storage and enhanced ... -
CO2 EOR Potential in the Brent Group at the Statfjord Field
(Master thesis, 2017)CO2 flooding is an enhanced oil recovery (EOR) technique that can be used to improve displace- ment efficiency and volumetric sweep efficiency. This is due to its favorable interactions with oil, which can be beneficial ... -
CO2 fluid flow information from quantitative time-lapse seismic analysis: Illustrated using seismic data from Sleipner, North Sea, Norway
(Doctoral thesis at NTNU;2015:308, Doctoral thesis, 2015) -
CO2 Injection in an Oil Reservoir with Gas Cap (Compositional Simulation Case at Heidrun Field Norway)
(Master thesis, 2006)A potential problem with CO2 Injection in oil reservoirs with gas caps is that gas cap may be contaminated by CO2. This could be an issue on the Heidrun Field where down dip using CO2-WAG is considered. Compositional ... -
CO2 saturation estimates at Sleipner (North Sea) from seismic tomography and rock physics inversion
(Journal article; Peer reviewed, 2018)CO2 saturations are estimated at Sleipner using a two‐step imaging workflow. The workflow combines seismic tomography (full‐waveform inversion) and rock physics inversion and is applied to a two‐dimensional seismic line ... -
CO2 Sequestration: The effect of carbonate dissolution on reservoir rock integrity.
(Master thesis, 2012)Since the environmental focus only becomes stronger and stronger in today’s society, industries like the oil and gas sector face some difficult challenges. Being the primary industry for CO2 production in the world requires ... -
CO2 STORAGE IN DEPLETED GAS FIELD RESERVOIR MODEL AND SENSITIVITY ANALYSIS USING NUMERICAL SIMULATION TECHNIQUES
(Master thesis, 2022)Worries are growing with the upsurge of GHG emissions and accumulation into our atmosphere where the chief producer of GHG is the combustion of fossil fuel for producing useful energy. Energy scientists, researchers and ... -
CO2-lagring i dedikerte bergrom
(Master thesis, 2014)Reduksjon av CO$_2$-utslipp er et tema som opptar svært mange og dermed investeres det mye penger i forskning og utvikling av ny og mer energieffektiv teknologi. Et av disse områdene er fangst av CO$_2$. Norcem har et ... -
Coastal glaciers advanced onto jameson land, east greenland during the late glacial-early holocene milne land stade
(Journal article; Peer reviewed, 2014)We report on 10Be and optically stimulated luminescence ages from moraines and glaciolacustrine sediments on eastern Jameson Land, East Greenland. Sampled landforms and sediment are associated with advances of outlet ... -
Coiled Tubing Drilling from Riserless Light Well Intervention Vessel
(Master thesis, 2017)Riserless light well intervention (RLWI) vessels currently have a proven capability of drilling offshore wells with coiled tubing (CT) to approximately 1000 meter measured depth (MD). The method has been used to drill ... -
COLD FLOW IN LONG-DISTANCE SUBSEA PIPELINES
(Master thesis, 2013)As the world?s appetite for energy continues to grow, oil and gas developments are moving to ever deeper subsea environments, thereby causing hydrates-related issues to become a growing concern for the industry. Hydrates ... -
Cold Flow Technical and Cost Efficiency Analysis
(Master thesis, 2017)Nowadays, subsea multiphase pipelines are commonly used in the deepwater oil-gas fields all over the world. However, when operating at such complex deepwater conditions, the problem of solid precipitation arises due to ... -
Collaborative optimization by shared objective function data
(Peer reviewed; Journal article, 2022)This article presents a collaborative algorithmic framework that is effective for solving a multi-task optimization scenario where the evaluation of their objectives consists of two parts: The first part involves a common ... -
Collapse prediction of pipe subjected to combined loads
(Peer reviewed; Journal article, 2020)Prediction of tubular performance has over the last decades improved with models that are more accurate. There is a trend in the oil and gas industry where traditional uniaxial modelling is given less importance and the ... -
Combined geophysical and rock physics workflow for quantitative CO2 monitoring
(Peer reviewed; Journal article, 2021)Safe CO2 storage requires conformance verification, i.e. confirmation that the pressure and CO2 accumulation are consistent with modelling forecasts within a given uncertainty range. Quantitative estimates of relevant ... -
Combined Inversion of PP and PS Seismic Data for Static and Dynamic Reservoir Characterization
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:85, Doctoral thesis, 2005)Reservoir properties are mainly determined based on well log information. However, wells in most reservoirs are sparse and widely spread compared to the size of the reservoir. Seismic data is thus one of the most important ... -
Combining terrestrial and marine glacial archives: A geomorphological map of the Nordenskiöldbreen forefield, Svalbard
