Salt Controlled Fluvial Systems in the Norwegian Danish Basin, Central North Sea; The Impact on Triassic Petroleum Prospectivity
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The Norwegian Danish Basin is situated in the intracratonic Central North Sea. During Triassic the basin filled with thick units of syn halokinetic arid to dryland fluvial successions of the Smith Bank Formation and the ... -
Salt tectonics on the Cod Terrace and Sørvestlandet High, Central North Sea
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Four high- to moderate-quality 3D seismic surveys and public well data were used to define the structural framework and understand the Mesozoic and Cenozoic structural evolution of the salt diapirs on the Cod Terrace and ... -
A Second-Order Finite Volume Method for Field-Scale Reservoir Simulation
(Peer reviewed; Journal article, 2023-08)Subsurface reservoirs are large complex systems. Reservoir flow models are defined on complex grids that follow geology with relatively large block sizes to make consistent simulations feasible. Reservoir engineers rely ... -
Sediment growth around salt diapirs: Analysis and interpretation using full-azimuth seismic data from the Central Nordkapp Basin, SW Barents Sea
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The Nordkapp Basin (Norwegian Barents Sea) comprises a large number of salt structures developed during Late Paleozoic-Early Mesozoic. Salt diapirism is dominant in this basin, and it influences all aspects of the petroleum ... -
Seismic and log characterization of the Rogaland Group in the Norwegian Central Graben to the Åsta Graben
(Master thesis, 2022)With the rapid transformation in the energy sector, near field exploration is becoming a large priority. Although, the Paleocene Rogaland Group has been a successful target in different areas of the Norwegian Continental ... -
The Seismic Imaging and Interpretation of Faults: A Case Study from the Snøhvit Field, Barents Sea
(PhD thesis UiS;568, Doctoral thesis, 2021-01)An accurate understanding of faults in the subsurface is critical to successful petroleum exploration and production. Faults define sediment distribution pathways during deposition, act as barriers or conduits to fluid ... -
Seismic imaging with primaries and multiples
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Multiples are usually considered as noise in seismic images due to their interferences with primary reflections. In recent years, new imaging methods have been developed which consider multiples as secondary sources to ... -
Seismic interpretation of the upper Paleozoic in the central part of the North Sea Southern Farsund basin.
(Bachelor thesis, 2021)The investigated area located in the North Sea and covers an area of ca. 1000 km2 between the Stavanger platform and the Norwegian-Danish basin. Farsund basin is an underexplored basin and here, we will examine the basin ... -
Seismic vulnerability to underground tunnels with particular focus on the Rogfast project.
(Bachelor thesis, 2022)During the last decades several studies of underground tunnels under seismic loads have been conducted. Classically, earthquakes have been associated with active plate boundaries and adjacent areas; however, seismic activity ... -
Sensitivity Analysis for Drilling data using Machine Learning models
(Master thesis, 2022)Over the last decade, machine learning models have become highly popular. Without requiring significant human participation, Machine Learning models improve the efficiency and dependability of any system. Machine Learning ... -
Sequence Stratigraphic Evaluation of Lower Goru Sequence (Massive Sands) and Sembar in Block ‘X’, Lower Indus Basin, Pakistan
(Master thesis, 2021)Block ‘X’ is situated in the prolific oil- and gas-producing Lower Indus Basin of Sindh Province, Pakistan where the Sembar-Goru Petroleum System features high-quality prodeltaic to open marine source rocks in the Lower ... -
A sequential decision and data analytics framework for maximizing value and reliability of CO2 storage monitoring
(Peer reviewed; Journal article, 2021-12)Carbon capture and sequestration (carbon capture and storage or CCS) represents a unique potential strategy that can minimize CO2 emissions in the atmosphere, and it creates a pathway toward a neutral carbon balance, which ... -
Simulation of immiscible WAG injection in a stratified reservoir -- performance characterization using a new dimensionless number
(Peer reviewed; Journal article, 2019)Water alternating gas (WAG) is a well‐established enhanced‐oil‐recovery process where gas and water are injected in alternating fashion. Good volumetric sweep is achieved as water and gas target both the oil residing in ... -
Simulation of Water Management Processes
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)Conformance control practices are commonly used to tackle issues related with injected fluids bypassing potentially oil-bearing formations, due to the presence of conductive fractures. To improve the prospect of such a ... -
Simulation study of wettability alteration enhanced oil recovery during co-current spontaneous imbibition
(Peer reviewed; Journal article, 2020-09)Naturally fractured reservoirs are highly dependent on capillary forces to recover hydrocarbons during water injection. Water can spontaneously imbibe and expel oil if positive capillary forces exist; purely counter-current ... -
Simulation study of wettability alteration enhanced oil recovery during co-current spontaneous imbibition
(Peer reviewed; Journal article, 2020)Naturally fractured reservoirs are highly dependent on capillary forces to recover hydrocarbons during water injection. Water can spontaneously imbibe and expel oil if positive capillary forces exist; purely counter-current ... -
Smart Water EOR potential in Brazilian oilfields
(Masteroppgave/UIS-TN-IER/2019;, Master thesis, 2019-06-15)The fact that the petroleum industry still invest a lot of money on different oil recovery techniques indicates that there is an increasing demand for oil that needs to be met. Water flooding is a common secondary oil ... -
Steady State Gas Flow from Tight Shale Matrix Subject to Water Blocking
(Peer reviewed; Journal article, 2021)This work studies 1D steady-state flow of gas from compressible shale matrix subject to water blocking toward a neighboring fracture. Water blocking is a capillary end effect causing wetting phase (e.g., water) to accumulate ... -
Steady State Relative Permeability Experiments with Capillary End Effects: Analytical Solutions including Derivation of the Intercept Method
(Peer reviewed; Journal article, 2020-04)Steady state relative permeability experiments are performed by coinjection of two (or more) immiscible fluids. The relative permeabilities can be calculated directly from the stabilized pressure drop and saturation of the ... -
