Effect of crude oil adsorption and asphaltene precipitation on sandstone wettability
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Wettability is an important property for oil recovery. It affects capillary pressure and controls fluids, location, and flow in the reservoir. By an increase in capillary pressure (due to increased water wetness), previously ... -
A Three-Phase Model for Tumor Cell Migration
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Flow of interstitial fluid (IF) has proven to have a significant effect on the migration of cancer cells through tissue due to the tumor cells ability to sense flow by secreting chemokines that convect in the flow direction ... -
Understanding Leakage Rates in Permanently Abandoned Wells by Studying Natural Hydrocarbon Seepages
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Permanent plug and abandonment (PP&A) of wells is steadily becoming more important on the Norwegian Continental Shelf (NCS), as a large number of fields are approaching end of their productive life. Combining operational, ... -
Simultaneous AVO inversion and seismic lithology cube estimation by using PP and PS angle stack seismic data of the Oseberg Field, North Sea

Well Modelling of H2S Production on a Field in the North Sea
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Hydrogen sulphide production can prove to be a very costly affair for exploration and production companies. Failure to implement efficient H2S control and mediation strategies can lead to a decrease in production assets, ... -
FEM Modelling and Simulation of Production Casing with Local Wear Damage
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Field data show that casing and production tubing experiences wear on both the internal and external parts of the tubular. The main mechanisms of the wear are the mechanical friction between drill string and casing, ... -
Dynamic interfacial tension measurement method using axisymmetric drop shape analysis
(Journal article; Peer reviewed, 2018-06)The current method describes a simple modification to the dynamic and equilibrium interfacial tension (IFT) measurement in a multiphase system (gas-liquid/liquid-liquid) by the Axisymmetric Drop Shape Analysis (ADSA) pendant ... -
Well Barrier Restoration Across Dual Cemented Liners
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)In the past years there has been an increased focus on decommissioning of wells in the NCS. Decommissioning of wells introduces significant investments with no financial returns and has for those reasons historically had ... -
An Experimental Study on Thermophysical Parameters of Production Wells and their Applications
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Transient pressure and temperature behavior in a wellbore develops as hot fluids from the reservoir move upward, exchanging heat with the surrounding formation. Because of heat exchange between the production fluid and ... -
Dashboard for visualization, evaluation and modeling of wellbore and field H2S production
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)For several years, continuously increasing amounts of hydrogen sulfide (H2S) are being produced from numerous fields on the Norwegian Continental Shelf as a result of reservoir souring. Reservoir souring – increasing ... -
Describing viscosity of IOR polymer solutions with differential non-Newtonian fluid models
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)The non-Newtonian viscosity of multiple of polymers was measured. For tests were taken polymers that are widely used in oil industry. They are: HEC; Xanthan gum; Polypack; Flopaam: 5115VHM, 5115VLM, AN 125VHM, AN 125VLM, ... -
Investigation of Geomechanical Effects and Other Controlling Parameters on Shale Gas Production
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Shale gas reservoirs are mainly characterized by their low matrix permeability, ranging from sub-nanodarcies to tens of microdarcies, which makes the economic production of these reservoirs rare without needing artificial ... -
An Overview and Discussion of MPD Systems used in Offshore Operations
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Globally, established fields are reaching maturity and easily accessible reserves have already been exploited. The remaining reserves are generally more difficult to drill and attempting to drill them using conventional ... -
Modelling and Simulation of Annular Pressure Build up
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Annular pressure buildup (APB) has been a concern for well design in the recent years. It is a phenomenon that relates mainly to subsea wells with possibly no means to release the pressure building up in closed annuli. ... -
