A study of the influence of organic matter on the geotechnical properties of an intermediate soil
(Master thesis, 2021)Organisk jord er i en byggrelatert sammenheng fryktet for sin myke oppførsel og sitt høye deformasjonspotensial. Når organisk materiale er tilstede i mineraljordarter har det tidligere blitt funnet at jordens egenskaper ... -
A Study of the Information Potential in Electrical Image Logs: Analysis and Calculations performed on FMI Curves
(Master thesis, 2012)This project focuses on measurements from the electrical image tool Fullbore Formation MicroImager (FMI). High resolution electrical image logs can determine individual layers in thinly bedded sand and clay sections that ... -
A study of the Particle Size Distribution (PSD), effect on primary flotation process
(Master thesis, 2011)Ingrid Vik has written this master thesis with the title: “A study of the Particle SizeDistribution (PSD), effect on primary flotation process”. This report has been written at the Department of Geology and Mineral Resources ... -
A Study of the Ultrasonic Measurements for Logging Behind a Steel Pipe: Expanding the proessing to improve the differentiation between heavy fluids and light solids
(Doctoral theses at NTNU;2019:375, Doctoral thesis, 2020)In petroleum applications using acoustic wave theory, the most used practice can be found in borehole geophysical methods, where acoustic logging has long been the foremost source for cement evaluation. Due to stricter ... -
A study of water chemistry extends the benefits of using silica-based nanoparticles on enhanced oil recovery.
(Journal article; Peer reviewed, 2015)Chemistry of the injected water has been investigated as an important parameter to improve/enhance oil recovery (IOR/EOR). Numerous extensive experiments have observed that water chemistry, such as ionic composition and ... -
A Theoretical and Numerical Analysis of CO2 injection in Gullfaks H
(Master thesis, 2011)By Injecting CO2 into the Tarbert formation Sector H of Gullfaks in the North Sea, additional 12.5 % can be recovered compared to water injection. This thesis discusses important factors for CO2 injection by studying a ... -
A Timelapse Development of the Levant Basin since the Early Pliocene - Documenting the Seismic Geomorphology and Stratigraphy of Depositional Elements
(Master thesis, 2017)Investigation of the seismic geomorphology of the overburden in the southeastern Levant Basin -
A3Mark: Seismic attribute benchmarking
(Journal article; Peer reviewed, 2018)Seismic attribute computation is one of the most active research and engineering topics in the computational geophysics world. Although numerous algorithms for seismic attribute computation have been developed, relatively ... -
Acid treatment as a way to reduce shale rock mechanical strength and to create a material prone to the formation of permanent well barrier
(Peer reviewed; Journal article, 2021)Utilization of natural shale formations for the creation of annular barriers in oil and gas wells is currently discussed as a mean of simplifying cumbersome plugging and abandonment procedures. Shales that are likely to ... -
Acoustic and Elastic Impedance Models of Gullfaks Field by Post-Stack Seismic Inversion
(Master thesis, 2013)Gullfaks is one of the major hydrocarbon producing fields in the Norwegian continental shelf. This field has a quite complex geology which makes routine seismic interpretation a challenging task for understanding the ... -
Acoustic emission measurements in petroleum-related rock mechanics
(Doktoravhandlinger ved NTNU, 1503-8181; 77, Doctoral thesis, 2002)Acoustic emission activity in rock has usually been studied in crystalline rock, which reflects that rock mechanics has also mostly been occupied with such rocks in relations to seismology, mining and tunneling. On the ... -
Acoustic generation of underwater cavities - Comparing modeled and measured acoustic signals generated by seismic air gun arrays
(Journal article; Peer reviewed, 2017)Underwater vapor cavities can be generated by acoustic stimulation. When the acoustic signals from several air guns are reflected from the sea surface, the pressure drop at some locations is sufficient for cavity growth ... -
Acoustic signals in air and water generated by very shallow marine seismic sources: An experimental study
(Peer reviewed; Journal article, 2020)When a marine seismic source, like an airgun, is fired close to the water surface the oscillating bubble interacts with the water–air interface. The main interest for seismic applications is how this effect impacts the ... -
Acoustically induced cavity cloud generated by air-gun arrays—Comparing video recordings and acoustic data to modeling
(Journal article; Peer reviewed, 2018)For seismic air-gun arrays, ghost cavitation is assumed to be one of the main mechanisms for high-frequency signal generation. Ghost cavitation signals are weak for seismic frequencies (<300 Hz) and do not contribute to ... -
