Automatic evaluation of wavelength spectra from quartz by means of machine learning
Kvandal, Ove (Master thesis, 2022)I have for this thesis worked on automating the steps in evaluating wavelength spectra from quartz. To do this I have applied different machine learning algorithms suitable to the automation requirement at each step, and ... -
CO2 Injection in Shales for CCUS
Shahab, Armin (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-08-15)Shale gas production has had great impact on energy supply and fuel prices. Due to low permeability and reservoir complexity the recovery factors are still very low. A promising alternative to pressure depletion is injection ... -
Core Flooding for Analysis of Capillary End Effect and Multiphase Flow Properties
Nainggolan, Citra Kirana Lestari (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-07)The non-uniform saturations along the core is called capillary end effect. The capillary end effect is caused by the condition that the capillary pressure is zero outside the core. The presence of capillary end effect is ... -
Experimental Analysis of Oil Recovery in Core Samples
Salomonsen, Liva (Bachelor thesis, 2021)An experimental analysis of oil recovery in core samples during spontaneous and forced imbibition have been performed. Grey Berea sandstone cores with a permeability around 120 mD have been used in the experiments. The ... -
Influence of Adsorption Layer Thickness in Tight Compressible Shales subject to Gas Production
Abolghasemi, Erfan (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 ... -
A LSSVR-PSO machine learning model for the estimation of reservoir porosity from petrophysical well logs
Luo, Zongqiang (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-10)Reservoir porosity is a key parameter in the reservoir evaluation and geomechanics. To obtain accurate measurement of porosity can be time-consuming and expensive by core sampling or applying various well logging tools. ... -
Prediction efficiency of immiscible Water Alternating Gas Performance by LSSVM-PSO algorithms
Kengessova, Aizhan (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 ... -
Reactive flow in chalk at reservoir temperature – Experiment and simulation
Bukkholm, Erik Trøiel (Bachelor thesis, 2021)This thesis seeks to study how 0.219 M MgCl2 brine flooded through chalk cores at reservoir temperatures will chemically react when flooded through at various flowrates. We used two different chalk cores. The cores were ... -
Reactive flow with Sr-Ba-Mg brines in outcropped Mons chalk at reservoir conditions – experimental study
Herlofsen, Sander Sunde (Master thesis, 2022) -
Relative Permeability and Capillary Pressure Estimation from Core-flooding Experiments accounting for Capillary End Effects.
Pulido Vasquez, Eliana (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-07)Abstract Relative Permeability and Capillary Pressure Estimation from Core-flooding Experiments studying Capillary End Effects Relative permeability (Relperm) and capillary pressure (Cp) are fundamental input ... -
Reservoir simulation of measurements with an innovative tool to detect oil-water-contact
Helgø, Johan (Master thesis, 2022)Hydrotell is developing a tool which will measure the pressure difference between oil phase and water phase in reservoirs with hydraulic conductivity. This pressure difference is then used to locate the free water level ... -
Residual Gas Impact on Water Influx and Recovery Potential
Oswald, Christine (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. ... -
Water flooding of Eldfisk reservoir cores
Cherif, Yosra (Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)Enhanced Oil Recovery (EOR) and the effect of the aqueous chemistry on the mechanical strength of chalk have been extensively studied over the years. This is simply because the stability of the reservoir system is affected ...
