M.; Minde, Mona Wetrhus; Lourenco de Souza, Marcelo I.; Aasen, Jan Aage; Skadsem, Hans Joakim; Delabroy, Laurent (Peer reviewed; Journal article, 2021)A unique data set has been constructed based on the study of class G cement recovered from an oil well on the Norwegian continental shelf. The cement was placed between two casing sections and submitted to downhole conditions ... -
Characterization of annulus well cement quality to estimate the leakage potential in cement well barriers
Beltrán Jiménez, Katherine (PhD Theses;676, Doctoral thesis, 2022-11)Cement is nowadays the most used material that is placed inside of wells as a barrier element to ensure zonal isolation and avoid migration of fluids between the reservoir and surface. Sometimes the well integrity can be ... -
Compatibility between API equations and design limits plots for ellipse and circle of plasticity
Romero Rubio, Juan Manuel (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-01)This project presents a methodology to superimpose the API uniaxial and triaxial limits on the design limits plot. Complications due to a recent change of axis are resolved, producing practical design limits plots that ... -
A Comprehensive Completion Method Selection Based on Probability and Impact Matrix for Iris Production HPHT Well
Økland, Andreas (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-14)HPHT well completion require special attention to well design.
