Plug and abandonment operations and tool positioning
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)With aging oil fields, the Norwegian petroleum authorities are focusing on Plug and Abandonment (P&A) plans. Therefore efforts are being made, by relevant authorities, to improve standards and procedures for the P&A ... -
Plug and abandonment operations performed riserless using a light well intervention vessel
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-14)In a few years there will be a significant increase in wells that need to be permanently plugged and abandoned (PP&A). Statoil operates around 500 subsea wells on the Norwegian Continental Shelf (N.C.S), whilst there exist ... -
Plug and Abandonment Technology Evaluation and Field Case Study
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)In the North Sea, the average field age is increasing and a large number of wells needs to be plugged and abandoned in the future. P&A is regarded as an operation with no financial returns and is associated with significantly ... -
Plug and abandonment, milling operations and simulations
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)During plug and abandonment, there can be a need for removing casing to ensure that a proper cement barrier can be set. The conventional method for doing this is by performing milling oper ... -
Pore scale modeling of capillary pressure curves in 2D rock images
(PhD thesis UiS;213, Doctoral thesis, 2013-12-10)Capillary pressure is relevant to most processes of multiphase flow inporous media, as it controls the pore scale fluids distribution. Reliable capillary pressure curves are required to model and predict larger-scale ... -
Porosity and permeability development in compacting chalks during flooding of nonequilibrium brines: Insights from long-term experiment
(Journal article; Peer reviewed, 2015-05)We report the complete chemical alteration of a Liège outcrop chalk core resulting from a 1072 flow-through experiment performed during mechanical compaction at 130°C. Chemical rock-fluid interactions alter the volumetric ... -
Potential of evaporation for geothermal energy exploitation
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-13)This master thesis investigates the potential of using heat pipes as geothermal heating systems for domestic purposes. The total electric energy consumption in Norway used for heating purposes is estimated to be as much ... -
Pre/post-production uncertainty analysis applied on the Hyme field
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06)The objective of this master thesis is to quantify how the estimated uncertainty, associated with the Hyme field, will change as more data becomes available. This will be done by identifying the key uncertainties and ... -
Prediction of dispersions and emulsions by using LedaFlow Q3D
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Well streams in pipelines are often transported over relatively long distances. The well streams often consist of simultaneous flow of gas, oil and water. Oil and water affect each other by making emulsions, which influence ... -
Preparation of Activated Carbon from Biomass for High Performance Supercapacitors
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Activated carbon was successfully synthesized from waste paper by physical, chemical and a combination of both activation procedures. The chemically activated carbon samples was achieved by using H3PO4 and KOH as agents. ... -
Processing and analysis of Vertical Seismic Profile data acquired while drilling (VSP-WD)
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)A Vertical Seismic Profiling While Drilling (VSP-WD) survey method was used to acquire data for processing analysis. This survey carried out in West Cameron in Offshore Louisiana by Schlumberger in 2005. A seismic source ... -
Processing techniques to enhance imaging of ultra-high frequency seismic data acquired with P-Cable technology
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)P-Cable seismic acquisition system is a rather new technology; developed through the past 20 years. Consequently, the use of P-Cable technology has been limited, although researchers still believe that further improvements ... -

Proper Cementing to Reduce Time and Cost
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)This work brings up some important aspects of cementing procedure with the aim of reducing WOC time, avoiding remedial cementing and referring to some new technologies regarding plug and abandonment. In the beginning, a ... -
Provenance of the Upper Cretaceous Lange-Lysing deep-marine sandstone in the Norwegian Sea: with implication for reservoir quality.
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)The provenance and reservoir properties of Upper Cretaceous Lange-Lysing sandstone in the Norwegian Sea have been determined by using integrated whole-rock geochemical, petrographic and detrital zircon U-Pb age dating by ... -
PSV sizing verification for Alvheim process equipment during gas blowby scenarios
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The EPCI (Engineering, Procurement, Construction and installation) contractor which delivered the PSVs to Alvheim states that the PSVs are sized to handle a gas blowby scenario. Marathon Norge AS does not hold any documentation ... -
Raman spectroscopy applied to enhanced oil recovery research
(Master thesis, 2015-06-09)It is well established that aqueous chemistry affects the mechanical strength of chalk. Seawater tends to weaken chalk at reservoir temperatures and consequently the recovery rate. As more than 50 % of the oil in existing ... -
