An experimental study of unsupported pipe buckling in live well intervention
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)In this experimental study, unsupported pipe experiments are conducted. Information regarding intervention operation, focusing on snubbing operations in live well interventions and unsupported buckling during these operations, ... -
An Experimental Study on Thermophysical Parameters of Production Wells and their Applications
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Transient pressure and temperature behavior in a wellbore develops as hot fluids from the reservoir move upward, exchanging heat with the surrounding formation. Because of heat exchange between the production fluid and ... -
An Overview and Discussion of MPD Systems used in Offshore Operations
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Globally, established fields are reaching maturity and easily accessible reserves have already been exploited. The remaining reserves are generally more difficult to drill and attempting to drill them using conventional ... -
Analysis of pore pressure measurements in exploration wells in the Norwegian North Sea
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-12)The aim of this thesis was to examine the pore pressure measurements in the Norwegian North Sea. To study the possibility of the overpressure being an indicator that can increase the probability of hydrocarbon discoveries ... -
Applications and Selection of Dissolvable Materials in Well Completions
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Dissolvable materials are an emerging technology in the petroleum industry with multiple areas of application, the chief among them being multistage well stimulation. The challenges associated with removal of traditional ... -
Assessing the Reliability of Physical Non-Newtonian Fluid Models for Saline FLOPAAM Polymer Solutions
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07)Experiments were conducted to investigate the impact of salt (NaCl) on rheological properties of specifically FLOPAAM 5115 VHM and FLOPAAM 3630-S polymers. These polymers were dissolved in brines of various salinity levels ... -
