(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020)Drilling fluids are an essential part of any drilling operation and it offers several functions of great importance, such as controlling the wellbore pressures and transporting cuttings to the surface. The design of a ... -
New Simple Analytical Surge/Swab Pressure Model for Power-Law and Modified Yield-Power-Law Fluid in Concentric/Eccentric Geometry
(Peer reviewed; Journal article, 2023)The axial movement of pipe in and out of the well generates positive (surge) and negative (swab) pressures that will impact the well pressure. When the swab and surge effects cause well pressures outside the allowable ... -
NiFe hydrotalcite-derived catalyst for CO2 reforming of methane: the impact of calcination and reduction temperature
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)ABSTRACT Carbon dioxide (CO2) emissions has become a major environmental concern for today’s society. As energy demand keeps on rising, the transition to cleaner energies is not fast enough to completely reduce greenhouse ... -
