• Fluid-Rock Interactions for CO2 Geological Storage in Chalk 

  Yu, Tongtong (Master thesis, 2022)

  CCS has been recognized as an effective strategy to limit the temperature rise to 1.5 °C by 2050 under the Paris Agreement. As a result, more than 50 CCS pilot or large-scale projects have been commissioned in recent ...

• A pore-to-core scale investigation of hysteresis for CO2 storage processes using a discrete-domain method 

  Engarnevis, Nazila (Master thesis, 2022)

  In this thesis we have studied a discrete-domain method that is implemented to demonstrate the immiscible, two-phase displacements of two fluids, namely CO2 and water (or brine) in an originally water-saturated reservoir ...

• Simulation Study and Modelling Improvements for the Bullheading Process 

  Abdelgadir Mohammed, Mohammed Elsiddig (Master thesis, 2022)

  In a bullheading operation, selecting the right pumping rate is vital to the job's success. A too low pumping rate may not displace the undesired fluid back into the formation, and a too-high rate generates high surface ...
