    • Ostwald ripening of trapped gas bubbles in porous media : A pore-scale perspective 

      Singh, Deepak (PhD thesis UiS;747, Doctoral thesis, 2024)
      Ostwald ripening of gas bubbles is a thermodynamic process for mass transfer, which is significant for both foam-enhanced oil recovery and underground gas storage. During recovery, it can impact the macroscopic efficiency. ...

    • Performance evaluation of subsea petroleum activities utilizing vessels 

      Valeev, Airat (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-07)
      Global consumption of the fossil fuels is continuously growing. The oil and gas industry is extending the frontiers of exploration and production towards challenging areas such as deep-water zones and arctic regions. ...

    • Pump pressure manipulation during MPD connection 

      Meling, Kristoffer (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-14)
      Over time the remaining oil prospects are becoming harder to drill and managed pressure drilling is a tool that can be used to reach target depth in depleted reservoirs or similar narrow margin scenarios. In any narrow ...

    • Reliability-Based Casing Design with Focus on an APB Collapse Scenario 

      Bjørndal, Erling (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)
      In times of unstable oil price, optimization related to casing and tubing design becomes more important than ever. Reducing cost and at the same time ensuring reliable and safe drilling and completion installations becomes ...

    • Simulating Managed Pressure Drilling and well control scenarios on test rig 

      Sandviknes, Anders Stave (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-12)
      The need for new methods for drilling wells is increasing, and new technology is introduced to the industry in order to solve the challenges we face. We are facing tougher and more challenging fields to drill. This includes ...

    • Simulation of Oil Recovery Process – Co-current Spontaneous Imbibition in Fractured Reservoirs 

      Ceballos, Anibal (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-14)
      A large fraction of the world petroleum reserves is made up by Naturally Fractured Reservoirs (NFR) which are usually produced by waterflooding. The injected water flows primarily through the fracture network and cover the ...

    • Stability assessment of PITT tracer candidate compounds: the case of benzyl alcohols 

      Silva, Mario; Stray, Helge; Bjørnstad, Tor (Journal article; Peer reviewed, 2018-04)
      The selection of compounds used as inter-well tracers has traditionally been done taking into consideration the goal of the test and the ease in analyzing the chemicals used. This often led to improper selection of the ...

    • Synthesis, characterization, and activity of bimetallic Ni-Fe hydrotalcite-derived catalysts in dry reforming of methane 

      Huynh, Huong Lan (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)
      The extensive amount of carbon dioxide (CO2) emitted into atmosphere is arguably considered to be the main reason for global climate change due to the greenhouse effect. For decades, considerable efforts have been devoted ...

    • The Physics of Buoyancy, Effective Tension and Pinching-off Effect 

      Landivar Argandona, Marcelo Gerardo (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-13)
      The thesis addresses at the beginning the understanding of the development of forces that result in buoyancy, and the concept of effective forces. Then, it continues more in-depth with an application of effective forces ...

    • Transport of CO2 In Porous Media – A Visualisation Study 

      Chauhan, Jaldeepsinh (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)
      The increase in global energy demand coupled with a need to stabilize CO2 emission levels has called for the development of a strategy with the potential to make energy `greener'. One such strategy is Carbon Capture ...

    • Viscosity Models for Drilling Fluids: Herschel-Bulkley Parameters and Their Use 

      Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2020-10)
      An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for drilling fluids. If data from automatic viscosity measurements exist, the parameters should be selected from relevant shear rate ...

    • Well Modelling of H2S Production on a Field in the North Sea 

      Mburu, Andrew (Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)
