Analytical model for J-tube pull-in
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)As long as J-tubes are installed during the platform installation, only minor thing can be changed after installation. The method implies pulling the pipeline through J-shaped tubes (J-tube). In spite of the all the ... -
Analytical modeling and correction of steady state relative permeability experiments with capillary end effects – An improved intercept method, scaling and general capillary numbers
(Peer reviewed; Journal article, 2021)Steady state relative permeability experiments are performed by co-injection of two fluids through core plug samples. Effective relative permeabilities can be calculated from the stabilized pressure drop using Darcy’s law ... -

Analytical solutions for forced and spontaneous imbibition accounting for viscous coupling
(Journal article; Peer reviewed, 2019-11-22)Fluid-fluid momentum transfer can cause higher flow resistance when fluids flow in opposite directions as compared to the same direction. Conventional modelling of flow in porous media using simple, saturation dependent relative ... -
Analytical solutions for forced and spontaneous imbibition accounting for viscous coupling
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06)Theoretical and experimental work has shown that fluid mobilities can depend on flow configuration, and are typically lower when fluids flow in opposite directions as compared to when they flow in the same direction. Such ... -
An Analytical TOOLBOX for the Characterization of Chalks and Other Fine-Grained Rock Types within Enhanced Oil Recovery Research and Its Application—A Guideline
(Peer reviewed; Journal article, 2022-06)Analyses of fine-grained rocks like shales, cherts, and specifically chalk are challenging with regards to spatial resolution. We propose a “toolbox” to understand mineralogical alteration in chalk, especially those induced ... -
Analyticity in Several Complex Variables
(Masteroppgave/UIS-TN-IMF/2020;, Master thesis, 2020)there are many similarities between complex analysis in several variables and one variable but there are also some important differences between holomorphic functions of a single variable and holomorphic functions of $n$ ... -
Analyze Gelling Properties for Time-Dependent Non-Newtonian Fluids
(Master thesis, 2022)Drilling fluids are visco-elastic materials. This means that they behave as a viscous fluid when subject to sufficient shear stress and like an elastic solid when they are in near static conditions. Both properties are ... -

Analyzing vertical lift performance in a complex gas lift well gometry
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)This study mainly investigates the vertical lift performance in a complex gas lift well geometry. Prosper is used to do gas lift design. OLGA is used to analyze the dynamic well behavior based on the gas lift design from ... -
Analyzing zonal well performance measured by production logging from Snorre A
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013)This thesis seeks to investigate zonal well performance on the Snorre A field. The goal is to further understand the value and limitations of the expected performance based on theoretically calculated data versus the actual ... -
Anchor damage assessment of subsea pipelines - optimization of design methodology
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-12)The world’s energy resources on land are getting depleted, and mush attention is given to the development of offshore fields. Over the past years, new reserves located offshore have been regularly discovered. Once the ... -
ANNMD - Artificial Neural Network Model Developer
(Working paper UiS, Research report, 2010-06)This booklet presents software for Artificial Neural Network (ANN) modeling called Artificial Neural Network Model Developer (ANNMD). ANNMD is generic software for a system modeling with ANNs. Its development is based on ... -
Annotation Markers for runtime replication protocol selection
(Journal article; Peer reviewed, 2008)This paper presents an architecture enabling developers to easily and flexibly assign replication protocols simply by annotating individual server methods. This avoids using costly replication protocols for all object ... -
Annular frictional pressure losses for drilling fluids
(Peer reviewed; Journal article, 2020)In the paper it is demonstrated how a Herschel-Bulkley fluid model, where the parameters are selected from relevant shear rate range of the flow and are parametrically independent, can be used for pressure loss calculations. ... -
