Produced water challenges : influence of production chemicals on flocculation
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)Produced water is the largest volume waste from offshore oil and gas exploration and production processes. Water in varying quantities is always produced along with oil, and has to be separated from the oil. The quantity ... -
Evaluation of DAPI direct count, computer assisted and plate count methods
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)The feasibility of using automatic counting of bacteria stained with highly specific and sensitive fluorescing DNA stain DAPI, 4',6-diamidino-2-phenylindole, and direct manual counting to enumerate both pure culture of ... -
Biodegradation and chemical characterization of petroleum diesel hydrocarbons in seawater at low temperatures
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010-06)Petroleum hydrocarbons are a major source of marine contamination. Biodegradation, which is fundamental for the natural attenuation of these hydrocarbons in nature, involves mineralization or transformation of organic ... -
A study of the interaction between a kinetic hydrate inhibitor and selected corrosion inhibitors
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)In field operations where natural gas hydrates can occur and CO2 corrosion is a problem, chemicals called inhibitors can be employed. Kinetic hydrate inhibitors (KHIs) and corrosion inhibitors (CIs) are added in small ... -
Pressure effect on biodegradation of hydrocarbons: Naphthalene and BTEX
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Oil and gas are the most important energy resources in the global economy today. Even though there is a growing concern for global heating, no real alternatives have been found. Current political disturbances in the Arab ... -
Carbide formation on carbon steels in CO2 corrosion by use of applied anodic current
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)The present study aims to validate the method in enriching of iron carbide surface from carbon steels in CO2 corrosion. Applying an anodic current to carbon steel electrodes by galvanostatic measurement was a selected ... -
Effect of pre-exposure of sulfur and iron sulfide on H2S corrosion at different temperatures
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)The study has been carried out to investigate the effect of elemental sulfur and iron sulfide on corrosion behavior of carbon steel in sour environment. It was found that both compounds could form a protective layer of ... -
