Conductive epoxy/carbon nanofiber coatings for scale control
Edvardsen, Laura; Grandcolas, Mathieu; Lædre, Sigrid; Yang, Juan; Lange, Torstein; Bjørge, Ruben; Gawel, Kamila (Peer reviewed; Journal article, 2021)Calcium carbonate (CaCO3) is one of the most widespread scaling minerals and has been a long-standing problem within many industrial sectors. Scaling of calcium carbonate on conductive surfaces can be prevented electrochemically ... -
Effect of carbonation on bulk resistivity of cement/carbon nanofiber composites
Gawel, Kamila; Wenner, Sigurd; Edvardsen, Laura (Peer reviewed; Journal article, 2021)The conductivity of cement/carbon nanofiber (CNF) composite materials has previously been shown to be affected by parameters such as e.g. CNF content or water to cement (w/c) ratios, water saturation and temperature. ... -
Effect of Field Caprock Shale Exposure to CO2 on Its Mechanical Properties—A Comparison of Experimental Techniques
Cerasi, Pierre; Duda, Marcin; Edvardsen, Laura; Agofack, Nicolaine; Bhuiyan, Mohammad Hossain (Peer reviewed; Journal article, 2022)Laboratory tests were performed on the Draupne shale formation, which may serve as a seal over CO2 storage sites. Different techniques were used to assess the integrity and mechanical properties of the shale, with the main ... -
Electrochemical enhancement and inhibition of calcium carbonate deposition
Edvardsen, Laura; Gawel, Kamila; Wenner, Sigurd; Gawel, Bartlomiej; Torsæter, Malin (Peer reviewed; Journal article, 2020)Calcium carbonate is by far the most widespread scaling material. Its deposition in pipes and flowlines has been a long-standing problem for many industries. Hence, a lot of research is devoted to scale inhibition. One of ... -
Electrochemically Enhanced Deposition of Minerals from Synthetic Reservoir Brine
Edvardsen, Laura; Emmel, Benjamin Udo; Bhuiyan, Mohammad Hossain; Wenner, Sigurd; Gawel, Kamila; Torsæter, Malin (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)In this paper we ask the question whether or not electrochemically enhanced deposition of minerals can be utilized to repair leakage paths existing in cement plugs in wells. Electrical polarization of two electrodes may ... -
Electrochemically Enhanced Deposition of Scale from Chosen Formation Waters from the Norwegian Continental Shelf
Edvardsen, Laura; Gawel, Kamila; Bhuiyan, Mohammad Hossain; Torsæter, Malin; Emmel, Benjamin (Peer reviewed; Journal article, 2022)Reservoir formation waters typically contain scaling ions which can precipitate and form mineral deposits. Such mineral deposition can be accelerated electrochemically, whereby the application of potential between two ... -
Experimental Investigation of the Influence of Injection Pressure and Clay Smear on Fault Reactivation for Co2 Storage
Griffiths, Luke; Park, Joonsang; Cerasi, Pierre; Edvardsen, Laura; Wüstefeld, Andreas (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Induced microseismicity from subsurface engineering projects such as geothermal heat exploitation and CO2 storage can be a show-stopper and halt the development of a site. While microseismicity correlates with fluid injection ... -
Fast Evaluation of Caprock Strength Sensitivity to Different CO2 Solutions Using Small Sample Techniques
Edvardsen, Laura; Bhuiyan, Mohammad Hossain; Cerasi, Pierre; Bjørge, Ruben (Peer reviewed; Journal article, 2021)The Draupne shale is a rock formation functioning as overburden for gas reservoirs in the Norwegian Sea and potentially as caprock for future CO2 storage locations as well. In this paper, the Draupne shale was exposed to ... -
Monitoring of Co2 Well Plug Integrity. Electrical Response of Cement/CNF Sensor to Mechanical Load, Water Saturation and Carbonation
Gawel, Kamila; Wenner, Sigurd; Taghipour, Ali; Szewczyk, Dawid; Edvardsen, Laura; Brocks, Anette; Hagen, Anna Stroisz; Gawel, Bartlomiej; Bjørge, Ruben; Ghaderi, Amir; Cerasi, Pierre; Malin, Torsæter (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)CO2 storage wells will eventually need to be permanently plugged and abandoned. Subsidence, fault/fracture reactivation or chemical degradation can all adversely affect well plug integrity leading to CO2 leakages. Thus, ... -
A Review of Well Integrity Based on Field Experience at Carbon Utilization and Storage Sites
Iyer, Jaisree; Lackey, Greg; Edvardsen, Laura; Bean, Andrew; Carroll, Susan; Huerta, Nicolas; Smith, Megan; Torsæter, Malin; Dilmore, Robert; Cerasi, Pierre (Peer reviewed; Journal article, 2021)Maintaining well integrity is critical to the success of geologic carbon storage (GCS) and carbon dioxide enhanced oil recovery (CO2-EOR) operations. Wells that experience leakage because of integrity issues can potentially ... -
The role of electrical current mode in calcium carbonate deposition on conductive carbon nanofiber–epoxy coating
Edvardsen, Laura; Grandcolas, Mathieu; Lædre, Sigrid; Yang, Juan; Lange, Torstein; Bjørge, Ruben; Gawel, Kamila (Peer reviewed; Journal article, 2024)Calcium carbonate is one of the most common scaling minerals. In this paper we have used different electrical current modes (direct current [DC], pulsed DC, and alternating current [AC]) to control the amount, morphology, ... -
Screening, Monitoring, and Remediation of Legacy Wells to Improve Reservoir Integrity for Large-Scale CO2 Storage—An Example From the Smeaheia Structure in the Northern North Sea
Romdhane, Mohamed Anouar; Emmel, Benjamin; Zonetti, Simone; Dupuy, Bastien; Gawel, Kamila; Edvardsen, Laura; Bhuiyan, Mohammad Hossain (Peer reviewed; Journal article, 2022)Carbon capture and storage (CCS) is an inevitable action to achieve CO2 emission reduction targets including becoming net-zero by 2050. Increased efforts are therefore required to identify suitable locations for large-scale ...
