Biomarker responses and accumulation of polycyclic aromatic hydrocarbons in Mytilus trossulus and Gammarus oceanicus during exposure to crude oil
Turja, Raisa; Sanni, Steinar; Stankeviciute, Milda; Butrimaviciene, Laura; Dévier, Marie-Helene; Budzinski, Helene; Lehtonen, Kari K. (Peer reviewed; Journal article, 2020)In the brackish water Baltic Sea, oil pollution is an ever-present and significant environmental threat mainly due to the continuously increasing volume of oil transport in the area. In this study, effects of exposure to ... -
Environmental impacts of produced water and drilling waste discharges from the Norwegian offshore petroleum industry
Bakke, Torgeir Heggelund; Klungsøyr, Jarle; Sanni, Steinar (Journal article; Peer reviewed, 2013-09)Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research on the biological ... -
An environmental risk assessment framework for enhanced oil recovery solutions from offshore oil and gas industry
Vora, Mehul Arun; Sanni, Steinar; Flage, Roger (Peer reviewed; Journal article, 2021)Environmental risk assessments are necessary to understand the risk associated with enhanced oil recovery (EOR) solutions and to provide decision support for choosing the best technology and implementing risk-reducing ... -
Environmental risk assessment of enhanced oil recovery solutions
Vora, Mehul (PhD thesis UiS;, Doctoral thesis, 2023)The overall objective of the research presented in this thesis is to contribute new knowledge about the environmental risk related to shortlisted products and processes developed at the National Improved Oil Recovery (IOR) ... -
Environmental risk assessment of inter-well partitioning tracer compounds shortlisted for the offshore oil and gas industry
Vora, Mehul Arun; Njau, John-Sigvard Gamlem; Sanni, Steinar; Flage, Roger (Peer reviewed; Journal article, 2022-05)Quantifying residual oil saturation (SOR) in the inter-well region of oil and gas reservoirs is key for successfully implementing EOR solutions. Partitioning inter-well tracer tests (PITTs) has become a common method for ... -
Environmental Risk Assessment of Seven Potential Enhanced Oil Recovery Partitioning Inter-Well Tracer Candidates.
Njau, John-Sigvard (Master thesis, 2021)An environmental risk assessment was conducted to characterise and compare the risk of seven shortlisted partitioning inter-well tracer candidates. The candidates were: Pyridine, 2-3-Dimethylpyrazine, 2,6-Dimethylpyrazine, ... -
Exposure and effects of synthetic enhanced oil recovery polymers on the Norwegian Continental Shelf
Vora, Mehul Arun; Sanni, Steinar; Lyng, Emily; Flage, Roger (Peer reviewed; Journal article, 2023-12)Synthetic polymers are planned to be used for more efficient oil recovery from offshore oil reservoirs. Using synthetic polymers offshore may lead to these being released into the marine environment through produced water ... -
Faunal and Microbial Sediment Community Disturbances Caused by Organic and Inorganic Contamination
Eli, Alexander Ishaya (Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06)There are ongoing developments to enable treatment of oil based drill cuttings with subsequent deposition offshore rather than the current practice to transport and treat such material on land. A sample from a step in the ... -
Framework for environmental risk assessment and management of deep-sea mineral mining of massive seafloor sulfide deposits
Lukoseviciute, Salva Marija (Master thesis, 2022)The global interest in exploiting deep-sea minerals has increased over the last couple of decades due to the rising demand for valuable metals required for technological development. However, due to significant scientific ... -
Implication of forms and distribution of phosphorous in sediments of three Stavanger lakes and ponds of constructed wetland on the potential for sedimentary phosphorous release and future eutrophication.
Nadelyaeva, Yulia (Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-07-27)Excess of bioavailable phosphorus in fresh-water systems results in algal blooms and subsequent biogeochemical activities which in turn as positive feedback can escalate eutrophication and significantly reduce water quality. ... -
Improving and evaluating methods of the analysis of microplastics from environmental samples
Ferreira, Natalia (Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-15)The objective of this thesis was to improve the methodology in the studies of the microplastics (MPs) in the laboratory and from environmental samples. The main application for this purpose was by the use of a quality ... -
Oil Spill clean-up methods; state of the art
Shazif, Muhammad (Master thesis, 2022)Treatment of oil spills and natural dissolvable contamination overall is a significant issue; a few methods are being worked on to eliminate oil from water. A few states of the art oil spill clean- up technologies are ... -
