Cementing Geothermal Steam Wells
Haavik, Inger Lill (Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Cementing wells with severe temperatures and/or pressures has become a common matter over the years. Running casing and designing the cement job is very difficult with temperatures above 150°C (300°F) which is a common ... -
Development and Characterization of Norite-Based Cementitious Binder from an Ilmenite Mine Waste Stream
Khalifeh, Mahmoud; Saasen, Arild; Larsen, Helge Bøvik; Hodne, Helge (Journal article; Peer reviewed, 2017-08)Norite is a major type of solid waste generated during the production of ilmenite. This study focuses on the usability of norite as a solid precursor of alkali-activated cement. Sensitivity analysis was performed to find ... -
Evaluation of Downhole Tubing Disposal for Permanent Plug and Abandonment
Holsen, Andreas (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)A new method called Downhole Tubing Disposal developed by Oilfield Innovations for performing rigless permanent plug and abandonment is presented. Instead of pulling the production tubing, the tubing is weakened with ... -
Materials for optimized P&A performance: Potential utilization of geopolymers
Khalifeh, Mahmoud (PhD thesis UiS;292, Doctoral thesis, 2016-05)When a well reaches the end of its life-cycle, it must be permanently plugged and abandoned. Plug and abandonment (P&A) can easily contribute with 25% of the total drilling costs of exploration wells offshore Norway. The ... -
