Reservoir Modeling and Uncertainty Estimation: A Comparison Between Stochastic and Deterministic Inversion.
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-29)This study compares the uncertainty estimation based on both deterministic and stochastic inversion with the Gauss Simulation technique applied to modelling the distribution of limestone facies in a sand-shale reservoir. ... -
Reservoir Simulation of Chemical Inflow Tracers in Horizontal Wells
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-14)Conventional production logging tools can be challenging to deploy and interpret in long horizontal wells. Inflow tracer technology can address these challenges, by allowing continuous monitoring of the horizontal section. ... -
Resistivity of reservoir sandstones and organic rich shales on the Barents Shelf: Implications for interpreting CSEM data
(Peer reviewed; Journal article, 2021-11)Marine controlled source electromagnetic (CSEM) data have been utilized in the past decade during petroleum exploration of the Barents Shelf, particularly for de-risking the highly porous sandstone reservoirs of the Upper ... -
Review of Different Methods for Identification of Transients in Pressure Measurements by Permanent Downhole Gauges Installed in Wells
(Peer reviewed; Journal article, 2023)Permanent downhole gauges (PDG) are massively installed in injection and production wells operated in different industries such as oil and gas, geological CO2 storage, and the geothermal industry. These gauges provide a ... -
Rigorous Connectionist Models to Predict Carbon Dioxide Solubility in Various Ionic Liquids
