    • Advanced Casing Wear Model 

      Teigland, Andreas (Master thesis, 2017)
      Casing wear prediction is an important part of a well integrity assessment. Reduction in the thickness of the casing wall as a result of various wellbore operations can cause significant reduction in burst and collapse ...

    • Advanced Temperature Model for HPHT Conditions 

      Løbergsli, Knut Vegard (Master thesis, 2015)
      Temperature changes of wells are analyzed in this Thesis. Wells need to be designed for all planned operations in order to maintain well integrity for the well life. Well barriers need to be numerically assessed for ...

    • Advanced Tubing Design - Temperature Modeling 

      Lervik, Øystein (Master thesis, 2016)
      In casing and tubing design, one of the most important aspects is to make the well safe for operation. This includes many complex areas that need thorough understanding, with one being temperature prediction. This is a ...

    • Coiled Tubing Drilling from Riserless Light Well Intervention Vessel 

      Bergsli, Bendik Øverland (Master thesis, 2017)
      Riserless light well intervention (RLWI) vessels currently have a proven capability of drilling offshore wells with coiled tubing (CT) to approximately 1000 meter measured depth (MD). The method has been used to drill ...

    • Collapse prediction of pipe subjected to combined loads 

      Brechan, Bjørn Astor; Teigland, Andreas; Dale, Stein Inge; Sangesland, Sigbjørn; Kornberg, Even (Peer reviewed; Journal article, 2020)
      Prediction of tubular performance has over the last decades improved with models that are more accurate. There is a trend in the oil and gas industry where traditional uniaxial modelling is given less importance and the ...

    • Digital well planning - Well Intervention 

      Selmer, Håkon (Master thesis, 2021)
      Dagens olje og gass industrien har sett en formidabel fremgang i teknologi og utstyr som er nødvendig for å kunne gjennomføre stadig mer krevende brønnintervensjoner. Brønnplanleggingsprosessen har ikke sett den samme ...

    • Digital Well Planning: Next Generation Workflow 

      Bareksten, Magnus; Vambheim, Lars Djuve (Master thesis, 2022)
      Petroleumsnæringen er inne i en periode med høyt fokus på digitalisering og automatisering. Dette fokuset er spesielt drevet av en ambisjon om å redusere kostnader, effektivisere drift og øke sikkerheten. Flere nye ...

    • Evaluation and Testing of Thermoset Polymer Resin for Remedial Repair of Sustained Casing Pressure 

      Øyan, Even Gunnarsson (Master thesis, 2017)
      The number of petroleum wells exhibiting pressure build-up in the annulus as a result of lost cement integrity is evident, this is known as Sustained Casing Pressure (SCP). There are several factors contributing to lost ...

    • Evaluation of Industry Practice for Buckling Analysis in Well Design 

      Remmen, Trine (Master thesis, 2018)
      The development of horizontal drilling technology have enabled the production of oil and gas from thin layers. With the development of shallow, horizontal subsea wells, new challenges arises. The occurrence of compressive ...

    • Evaluation of Methods and Quality Barriers in Plug and Abandonment - Technology Advances, Physical and Governing Requirements 

      Aasnes, Mona Øygarden (Master thesis, 2017)
      Improving the present P&A operation with respect to costs and safety is of current interest to the petroleum industry. This is because this operation will frequently be performed in the future due to the large number of ...

    • Improved Casing Collapse Prediction with a Case Study of Asset Life Extension 

      Kornberg, Even Mikael (Master thesis, 2017)
      The current industry accepted standards of predicting collapse strength of casings are pessimistic and inaccurate. With wells being drilled ever deeper, high strength pipes are required in order to comply with rules and ...

    • Influence of Hole Trajectory and Direction on MWD Survey Errors 

      Hassan, Syed Muhammad Reza (Master thesis, 2018)
      Wellbore positioning is important to meet directional drilling objectives. Inaccurate wellbore surveys can lead to wellbore collision, failure to penetrate thin reservoir sections and drilling of relief wells etc. Such ...

    • Kick Tolerance for HPHT 

      Pettersen, Line (Master thesis, 2014)
      Safety is of great importance during a drilling operation. Where the worstcase scenario is that the well will kick and it will lead to a blowout. The bestway to handle disasters is to avoid them. Kick tolerance is a planning ...

    • Optimized Well Design on Brage 

      Jensen, Marielle (Master thesis, 2015)
      Slot recovery operations have the intention to increase the oil recovery and extend the lifetime of maturing fields. Keeping the well cost low is an important aspect of such operations, as the recoverable resources are ...
