(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-29)In this thesis the k-means clustering and a neural network is developed and used to classify capacitance data from multi phase flow in a horizontal tube. Theoretical background for the unsupervised machine learning ... -
Using plasma technology to remove scale from production tubing
(Master thesis, 2016-06)With its wide application in areas such as electronics, the car-, machine- and tool-making industries, energy technology, the optics industry, and textile, environmental, and medical technology, plasma technology is ... -
Utilizing down hole data, acquired by a multiple sensor down hole tool, to determine the PDC bit wear state.
(Masteroppgave/UIS-TN-IPT/2008;, Master thesis, 2008)By using real-time data from INTEQ`s CoPilot Real-Time Drilling Optimalization a search for dependable indications of the degree of the bit wear was done. This would improve decision making procedures for when to pull the ... -
Validation of the LedaFlow software applied to the well flow cases
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06)In recent years, there have been rapid advances in the field of transient multiphase simulators due to the fact that they have proven to be accurate and reliable for the vast majority of cases in the oil and gas industry. ... -
Water induced compaction of chalks with varying non-carbonate content : the effect of Mg2+ and pH of the injected brines
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The main objective for this study was to investigate the effect of alkaline brines on chalk, and the importance of non-carbonate content in chalk. This was done by flooding alkaline MgCl2 on Liège chalk – which has ... -
Water weakening of chalk: A mechanistic study
(PhD thesis UiS;11, Doctoral thesis, 2005)Since the detection of the Ekofisk subsidence some 20 years ago, there has been a considerable research activity concerning chalk behaviour in general, and mechanical properties particularly. Due to the importance of water ... -
Water weakening of chalks - comparsion of intact and fractured cores
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Even though Chemical induced compaction on high porosity chalks has been studied extensively, little attention was given to the impacts of fractures when chalk is exposed to various flooding brines. Due to the nature of ... -
Water-based enhanced oil recovery (EOR) by “Smart Water”: optimal ionic composition for EOR in carbonates
(Journal article; Peer reviewed; Doctoral thesis, 2011)The composition of the injecting brine has a profound effect on the efficiency of water-based enhanced oil recovery (EOR) methods. Recently, we observed that not only is the concentration of the active ions Ca2+, Mg2+, ... -
