Experimental and Theoretical Modelling of CO2 Injectivity : Effect of Fines Migration and Salt Precipitation
(PhD thesis UiS;, Doctoral thesis, 2017-11)Adequate well injectivity is required to inject large volumes of CO2 at acceptable rates through a minimum number of wells. Mineral dissolution and salt precipitation could impair CO2 injectivity and reduce the quality and ... -
Experimental assessment of cracked tubular joints repaired with crack-deflecting holes and weld-toe grinding
(Master thesis, 2023)Fatigue-induced cracks in tubular joints represent one of the major threats to the structural integrity of offshore infrastructure. Consequently, developing and researching efficient temporary and permanent repair solutions ... -
Experimental assessment of cracked tubular joints repaired with crack-deflecting holes and weld-toe grinding
(Peer reviewed; Journal article, 2023)Tubular joints in offshore structures for energy production are exposed to cyclic loading and may experience fatigue cracking. Presently, the inspection method commonly used for such structures will primarily detect whether ... -
Experimental Bench-Scale Study on Cuttings-Bed Erosion in Horizontal Wells
(Peer reviewed; Journal article, 2022)Cuttings-beds formation while drilling wellbores is a common challenge, especially for horizontal wells, as drilled particles have higher area to be deposited and form cuttings-beds, which can cause several problems such ... -
Experimental circulation loss study
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-07)Circulation losses could occur during any operation that involves pumping into a well. As of today, it is recognized as one of the most costly drilling problems. In some situation it might ... -
Experimental comparison of migration strategies for MEC-assisted 5G-V2X applications
(Peer reviewed; Journal article, 2022)The introduction of 5G technology enables new V2X services requiring reliable and extremely low latency communications. To satisfy these requirements computing elements need to be located at the edge of the network, according ... -
Experimental Design and Setup of Circulation Flow Loop - Using Particle Image Velocimetry
(Master thesis, 2017-07-25)Mud left static in a well over a longer period of time can begin to gel up or form filter cakes along the formation wall and in washout zones, which can be difficult to remove. Therefore, proper mud mobilization and removal ... -
