    • Automatisert rapportering av feil og hendelser 

      Wille, Egil; Hauge, Stein; Nybø, Roar; Onshus, Tor Engebret; Ottermo, Maria Vatshaug; Kråkenes, Tony; Mathisen, Bjørn Magnus (SINTEF rapporter;2022:01376, Research report, 2022)
      Formålet med denne rapporten har vært å gi næringen og Petroleumstilsynet (Ptil) økt kunnskap om systemer og prosesser som er nødvendig for å legge til rette for større grad av automatisert rapportering av feil, hendelser ...

    • Cuttings Transport With Oil- and Water-Based Drilling Fluids 

      Ytrehus, Jan David; Lund, Bjørnar; Taghipour, Ali; Saasen, Arild (Peer reviewed; Journal article, 2023)
      Deviated well sections are common in most modern offshore well construction designs. In the North Sea region, which is a good example of mature areas, practically all producer or injector wells have highly deviated well ...

    • Cuttings transport: On the effect of drill pipe rotation and lateral motion on the cuttings bed 

      Busch, Alexander; Johansen, Stein Tore (Peer reviewed; Journal article, 2020)
      Drill pipe rotation is considered a relevant factor for cuttings transport and hole cleaning. However, in the term “rotation” is often used as a moniker for the combination of plain drill pipe rotation around its own axis ...

    • On pragmatism in industrial modeling. Part III: Application to operational drilling 

      Johansen, Stein T.; Meese, Ernst A.; Zoric, Josip; Islam, Amunial; Martins, Dwayne W. (SINTEF Proceedings;2, Chapter, 2017)
      In this paper, we will apply the concepts of pragmatic industrial modelling to the development of a real time drilling support tool. We develop requirements to such a modelling tool, regarding both input and output, model ...

    • Reporting of incidents in automated systems during drilling operations 

      Ottermo, Maria Vatshaug; Wille, Egil; Bjørkevoll, Knut Steinar; Bodsberg, Lars; Evjemo, Tor Erik; Fjørtoft, Kay Endre; Jaatun, Martin Gilje; Myklebust, Thor; Okstad, Eivind (SINTEF rapporter;2023:00191 A, Research report, 2023-02-06)
      This work is a preliminary study of how incidents, near misses and deviations within automated systems are currently detected, registered and, if appropriate, reported to the Petroleum Safety Authority Norway (PSA), as ...

    • Review of two-phase flow models for control and estimation 

      Aarsnes, Ulf Jakob Flø; Flåtten, Tore; Aamo, Ole Morten (Peer reviewed; Journal article, 2016)
      Most model-based control and estimation techniques put limitations on the structure and complexity of the models to which they are applied. This has motivated the development of simplified models of gas-liquid two-phase ...
