      This thesis presents an advanced model for temperature predictions of a producing well. With today s low oil price, cost reduction has become paramount for many big oil companies. One way of reducing operational costs are ...
    • 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 ...
    • Analysis of Drilling Loads in Advanced Casing Design 

      Østvedt, Johan Holm (Master thesis, 2015)
      Casing design planning has during the last decades developed from manual calculations performed by the engineer himself, to the use of advanced simulation tools. The tools have become increasingly advanced, allowing the ...
    • Analysis of the Influence of Wellbore Deposits on Wireline Well Intervention Operations 

      Wold, Magnus Wingan (Master thesis, 2015)
      Well intervention activities are crucial for maintaining well performance and integrity throughout the whole lifecycle of oil producers and injectors. Typical operations involve perforation, logging, setting and pulling ...
    • Applications of Equations of State in Blowout and Relief Well Kill Simulation 

      Nilsen, Marius Staahl (Master thesis, 2016)
      A blowout is the most severe consequence of a well operation, and may cause a high negative impact on the surrounding environment and human safety, and financial distress for responsible companies due to clean up costs, ...
    • Automatic Lithology Prediction on Well Logs Using Kernel Density Estimation Trained By Analysis of Cuttings Data 

      Strømslid, Simen Kristoffer Steiro (Master thesis, 2017)
      Lithology interpretation is a vital part of the process when drilling oil and gas wells in the petroleum industry. The ability to predict what problems and challenges can occur along the well path and which precautions ...
    • Benefits of using Wired Drill Pipe in coring operations; analysis of data from the North Sea 

      Taraldsen, Turi (Master thesis, 2017)
      Mud Pulse Telemetry (MPT) is the standard way of communicating with downhole tools on the Norwegian Continental Shelf today. Wired Drill Pipe (WDP) is a high-speed telemetry alternative to traditional telemetry systems. ...
    • Boring av 800 meter dype energibrønner i Asker - Uttesting av boreteknologi og laboratoriemetoder for boreslitasje 

      Bones, Mette Nordmark (Master thesis, 2016)
      «Boring av 800 meter dype energibrønner i Asker uttesting av boreteknologi og laboratoriemetoder for boreslitasje» er en masteroppgave skrevet av Mette Nordmark Bones. Oppgaven er utført i forbindelse med faget TPG4910 ...
    • The capacity of creeping shale to form an annular barrier 

      Brendsdal, Are Olav Eriksen (Master thesis, 2017)
      This report was written in Pau, France, as part of an internship in Total E&P Drilling & Wells Division, Geomechanics Entity, under supervision of Kun Su. Shale displacing inwards in the wellbore is a well-recognized ...
    • Cement Displacement Efficiency in Rough Pipes 

      Johansen, Espen; Giil, Gunnar Lia (Master thesis, 2017)
      Research within casing string cementing is important in the oil industry. The integrity of an oil well is dependent on the quality of the cement job, and a poor cement job can put the environment, company economics and ...
    • 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 ...
    • Concentric Coiled Tubing Drilling System 

      Sandven, Håkon (Master thesis, 2015)
      A concept review of concentric coiled tubing drilling (CTD) system is performed in this Master thesis, hereafter named DualCTD. The main purpose is to investigate and present the advantages, limitations and applications ...
    • Creep and Consolidation in Pierre Shale - Identification of how time-dependent effects are influenced by alteration in pore fluid pH and changes in stress conditions 

      Lund, Elisabeth; Kleiven, Marta Laukeland (Master thesis, 2016)
