Qualitative and Quantitative Evaluation of Reservoir Quality Through Integrated Interpretation of CSEM, Seismic and Well Data - Pingvin Case Example
(Master thesis, 2017)In the last decades, the marine controlled source electromagnetic (CSEM) method has proven to be a useful tool for de-risking hydrocarbon prospects. Promising statistics and good data coverage in the Barents Sea have sparked ... -
Qualitative and quantitative experimental study of convective mixing process during storage of CO2 in heterogeneous saline aquifers
(Journal article; Peer reviewed, 2018)CO2 dissolution is considered as one of the most promising mechanisms for trapping of free-phase CO2 into brine. It causes an increased density of the brine and initiation of gravitational instability that eventually leads ... -
Quantative Analyzes of Seismic Inversion in Terms of Acquisition and Interpretation: Example From Southwest Haltenbanken Area in the Norwegian Continental Shelf
(Master thesis, 2012)In regular marine acquisition configuration, shallow sources and shallow streamers are used. Because of this configuration the high-frequency content of the seismic is favored, which is needed for sufficient vertical ... -
Quantification of time-varying groundwater flow in boreholes in fractured crystalline rock using long-term distributed temperature sensing
(Peer reviewed; Journal article, 2022)Quantification of groundwater flow is an important factor for several applications, such as water supply, boreholes for energy extraction/storage and drainage and flood prevention projects. In this study, distributed ... -
Quantifying Formation Hardness and Pore Pressure using the Bourgoyne-Young Drilling Model
(Master thesis, 2019)Formasjonshardheten og poretrykket er to viktige faktorer som må grundig undersøkes under planleggingsfasen og under boreoperasjonene av en brønn. Begge er korrelert til bore-effektiviteten og har potensial til å påføre ... -
Quantifying the effects of feeder chimneys on trapping mechanisms at the Sleipner CO2 storage site
(Master thesis, 2020)CO2 lagring fra Sleipner Øst feltet i akviferen Utsira Fm har foregått siden 1996. CO2- akkumulasjonen overvåkes nøye for å forhindre lekkasje, dette har blant annet foregått ved flere gjentatte seismiske undersøkelser. ... -
Quantitative Geology and resolution enhancements from image logs used in processing of thin layers.
(Master thesis, 2014)In this project I will focus on the quantitative application of FMI log as an addition of its use as a imaging log. The Fullbore Formation Microimaging is today commonly only used for qualitative studies of the borehole, ... -
Quantitative interpretation using inverse rock-physics modeling on AVO data
(Journal article; Peer reviewed, 2016)Quantitative seismic interpretation has become an important and critical technology for improved hydrocarbon exploration and production. However, this is typically a resource-demanding process that requires information ... -
Quantitative Measurements of Mineral Microstructures: Development, implementation and use of methods in applied mineralogy
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:194, Doctoral thesis, 2006)The project has been in applied mineralogy. Advanced characterisation techniques have been developed and used as a tool for quantitatively describing geological raw materials, middlings and end products for optimal ... -
Quantitative Refraction Traveltime Analysis of 3D Seismic Acquired After an Underground Blowout in the Central North Sea
(Master thesis, 2017)A quantitative refraction traveltime analysis was performed in this thesis. Refraction seismic can be used for monitoring in shallow parts of the subsurface where the contribution from conventional reflection data is ... -
Quantitative seismic characterisation of CO2 at the Sleipner storage site, North Sea
(Journal article; Peer reviewed, 2017)Reliable quantification of carbon dioxide (CO2CO2) properties and saturation is crucial in the monitoring of CO2CO2 underground storage projects. We have focused on quantitative seismic characterization of CO2CO2 at the ... -
Quantitative Seismic Geomorphology of Cenozoic submarine channel system in the Canterbury Basin, Offshore New Zealand: Implications for paleoenvironment interpretation and hydrocarbon prospectivity
(Master thesis, 2019)Nowadays, high resolution 3D marine seismic reflection data have allowed to study the morphology of submarine channels (primary conduits to transfer sediment from shelf to the basin) to understand the sedimentary processes ... -
Quantitative Seismic Interpretation using Rock Physics Templates - case examples from the Zumba field
(Master thesis, 2016)A post drill inversion study was done by Avseth et al. (2016) after the dry well result from Zumba prospect. The AVO inversion failed in a graben setting, caused by a hard carbonate layer and associated refraction just ... -
Quantitative Seismic Monitoring
(Doctoral theses at NTNU;2022:127, Doctoral thesis, 2022)Seismic data is the main input for reservoir characterization in developing plays, when - in general - only conceptual geological models and few wells are available. When repeated over time, in a process called 4D seismic ... -
Quantitative spatial analysis of rockfalls from road inventories: a combined statistical and physical susceptibility model
(Journal article; Peer reviewed, 2014)Quantitative spatial analyses and statistical susceptibility assessments based on road inventories are often complicated due to the registration of impacts instead of source areas. A rockfall inventory from the Norwegian ... -
A quantitative study of salinity effect on water diffusion in n-alkane phases: from pore-scale experiments to molecular dynamic simulation
(Peer reviewed; Journal article, 2022)Numerous mechanisms have been proposed to untangle the effect of a low concentration of dissolved salts in the water flooding medium. One potential mechanism for enhanced oil movement is proposed with osmosis effect, ... -
