Creating Value From Brown Fields Through High-Quality Decision Making
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06)Whether facing pandemics, negative oil prices or other crises, the key to value creation is to make good decisions. Decisions are always about the future and the one thing we know for sure about the future is that it is ... -
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, ... -
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 ... -
Effects of Potential Determining Ions and pH on the Wettability of Intermediate Wet Outcrop Limestone
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-13)The intent of this study is to determine if the wettability of slightly oil wet limestone can be shifted toward water wet using “Smart Water”. The theory of “Smart Water” in carbonates proposes that increasing the composition ... -
Influence of Adsorption Layer Thickness in Tight Compressible Shales subject to Gas Production
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)The gas transport in shale nanopores has always been a major concern in developing shale gas reservoirs. Different gas flow regimes in shale nanopores have been studied and classified during recent years. Some mathematical ... -
Investigating the impact of solvent salinity on the viscometric functions of IOR polymers
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)One of the promising methods of enhanced oil recovery (EOR) is injection of polymers dissolved in low salinity water. This leads to a dramatic increase in the sweep efficiency due to increased apparent viscosity. It is ... -
Multi-well Interference Test Analysis
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020)Understanding if there is any hydraulic communication, between the wells within a reservoir and a degree of the communication have been a subject of study for a long time. This information becomes crucial when injection ... -
Numerical and analytical analysis of flow in stratified heterogeneous porous media.
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-06)The groundwater flow through a porous media is well-researched to extend the basic knowledge in both academia and industry, specially the oil industry. The Boussinesq equation represents a water height of fluid spreads ... -
Optimal Core Restoration and the Effect of Initial Wetting on Oil Recovery in Chalk
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-12-15)The initial wetting condition of the reservoir rock is fundamental in the advanced oil recovery methods by waterflooding, in particular, in Smart Water EOR. The wettability alteration of the rock surface is induced by ... -
Optimizing carbonate core restoration procedures - Effect of crude oil saturation and mild cleaning
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Wettability has a big impact on how much we can recover by water flooding a reservoir, and there is a commercial potential for improvement done through alteration of the wettability. Studies have been conducted and shown ... -
Prediction efficiency of immiscible Water Alternating Gas Performance by LSSVM-PSO algorithms
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020)In this work the aim is developing LSSVM-PSO model capable of capturing the interplay between the most influential parameters (mechanisms) and recovery factor (RF) of WAG process in layered reservoirs. In a previous work ... -
Residual Gas Impact on Water Influx and Recovery Potential
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020)Whereas residual gas has been studied by many researchers, there has been little discussion about paleo residual gas. When encountered in a well, these dead gas columns are usually immobile, and the well is considered dry. ... -
