Development of One-Part Rock-Based Geopolymers for Downhole Cementing Applications
(Peer reviewed; Journal article, 2023-10)The use of geopolymers as a full replacement for cement in oil well cementing applications requires the development of not only environmentally friendly but also user-friendly cementitious materials. This study aims to ... -
Rheological Compatibility of a Hardening Spacer Fluid and Oil-based Drilling Fluid
(Peer reviewed; Journal article, 2023-08)In the placement process of the cement slurry, treatment fluids such as the spacer are pumped ahead of the cementitious slurry to minimize the contamination of the slurry by drilling fluid and ensure superior bonding to ... -
Safety and reliability improvements of valves and actuators for the offshore oil and gas industry through optimized design
(PhD thesis UiS;573, Doctoral thesis, 2021-02)Valves are essential components of piping systems in the oil and gas industry, especially offshore, where they are used for stopping or starting the fluid, flow regulation, and back flow prevention, as well as safety ... -
Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development
(Peer reviewed; Journal article, 2023)Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a ...
