Reproducing wettability in sandstone reservoir core material in laboratory core restorations
(Peer reviewed; Journal article, 2021-09)Replicating initial reservoir wettability conditions in core restoration by core cleaning and fluid restoration in the laboratory is of great importance. There are several core cleaning and restoration protocols used in ... -
Reservoir simulation of measurements with an innovative tool to detect oil-water-contact
(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
(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. ... -
Restoration of annular zonal isolation using localized casing expansion (LCE) technology: Treatment of near-horizontal test sections containing a free-water channel
(Peer reviewed; Journal article, 2021-11)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very difficult remediation attempts. Traditional methods for ... -
Retarding mechanism of Zn2+ species in geopolymer material using Raman spectroscopy and DFT calculations
(Peer reviewed; Journal article, 2022)Geopolymers are the most promising alternative to Ordinary Portland Cement for oil-well cementing and well abandonment. To that end, the slurry needs a required pumping time ensured by the addition of retarders. Although ... -
