Effect of Calcium Expansive Additives on the Performance of Granite-Based Geopolymers for Zonal Isolation in Oil and Gas Wells
Gomado, Foster Dodzi; Khalifeh, Mahmoud; Saasen, Arild; Kjøniksen, Anna-Lena; Sanfelix, Susana; Aasen, Jan Aage (Peer reviewed; Journal article, 2023)Geopolymers have emerged as a promising alternative to Portland cement for oil and gas wells. Achieving effective zonal isolation by use of geopolymers may require controlling their expansion. This study investigates the ... -
Exploration and Improvement of the Sealability Performance of Two-Part Granite-Based Geopolymer for Oil Well Cementing Applications
Gomado, Foster Dodzi (PhD Theses;821, Doctoral thesis, 2024)Zonal isolation is essential to producing hydrocarbon from the subsurface. Zonal isolation ensures the well integrity and efficiency of oil and gas wells by preventing fluid migration and ensuring optimal production in the ...
