Application of Multilateral Wells as an alternative solution for costs optimization
Zhambrovskii, Dmitrii (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Field completion techniques have progressed over the last twenty years. Today, different methods of well drilling can reduce total costs spent on single well construction. Multilateral wells is the primary example of ... -
Cement properties characterization from a section retrieved from an oil production well after 33 years of downhole exposure
Beltran Jimenez, Katherine; Gardner, Dave; Kragset, Steinar; Gebremariam, Kidane Fanta; Reales, Oscar A. 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. The conservatism of well completion is constantly put to the test by introducing and qualifying new equipment meant to enhance well performance, minimize HS&E ... -
Determination of steel/cement friction coefficient
Tugalevs, Nikolajs (Master thesis, 2023)Two different experimental approaches have been used to determine the kinetic coefficient of friction between carbon steel and concrete made of API class G well cement mixture. First experimental setup consists of sliding ... -
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 ... -
Effect of scaling and mixing procedure on cement slurry and hardened cement
Søyland, Heidi (Master thesis, 2022) -
Friction coefficcient in wells with black sticky stuff and scale
Nærland, Kristine (Bachelor thesis, 2022)Scale buildup is a common problem in oil and gas producing wells all over the world. It gives difficulties to both the production of oil and gas, as well as well intervention operations. The buildup of scale generates more ... -
Investigation of temperature effects on cement bases for shallow gas zone cementing
Seglem, Kim André (Bachelor thesis, 2021)Shallow gas can create challenges for well integrity, local and global environment. During drilling and completion of wells, shallow gas can create dangerous situations resulting to human, environmental and economic ... -
Possibilities and limitations for well intervention with CoilHose
Helland Vevatne, Viljar; de Lanlay, Yann-Erik (Bachelor thesis, 2022)The E&P business is constantly driving improvements to ensure safe and efficient operations and optimize production. Well Interventions are used to increase the production and extend the well lifetime which results in an ... -
Repeated push-out testing of expansive cement plug in casing
Iversen, Simon Groven; Åsly, Jan Christer (Bachelor thesis, 2023)In the petroleum industry, cement plays a crucial role during well operations as it connects the casing pipes to the formation and forms a seal that prevents fluid migration, ensuring well integrity. The ability of the ... -
