Experimental Study of Hydraulic Sealability and Shear Bond Strength of Cementitious Barrier Materials
(Peer reviewed; Journal article, 2021-06)In this experimental study, two different cementitious materials, including (i) a class of expansive cement currently used for plug and abandonment (P&A) operations and (ii) a non-cement-based naturally occurring rock, ... -
Experimental study of indentation related to slips design for well intervention plug
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013-06)On behalf of the well technology E plug, an experimental study has been conducted on the subject of indentation related to a mechanical component called slips. Slips are a type of metal wedge element with sharpened teeth ... -
Experimental Study of Loss Circulation Materials Bridging Performance in K/Na-formate based Drilling Fluids
(Master thesis, 2021)The loss of drilling fluid is one of the main concerns of the petroleum industry, causing excessive expenditure both for operational and increasing the non-productive drilling time (NPT). The NPT associated with loss ... -
Experimental study of low salinity EOR effects from the Varg field
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The extra oil recovery obtained when flooding a sandstone reservoir with low saline water is called low salinity (LowSal) effect. The term salinity refers to amount (and type) of salt that makes up the ionic composition ... -
Experimental Study of Particle Dynamics in Circular Channel Flow
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)The study of liquid-particle interaction is the vital importance in many industries, especially for the petroleum well drilling and hole-cleaning operations. The data obtained from laboratory-scale experiments, simulations, ... -
Experimental study of physical, chemical and mechanical properties of enset and sisal fibers
(Peer reviewed; Journal article, 2021)The properties of composites depend on type and properties of the fiber, fiber structure and treatment. In this study, effects of NaOH treatment on the physical, chemical and mechanical properties of fibers collected from ... -
An Experimental Study of the Enhanced Mass Transfer Process by CO2 Absorption for Carbon Storage in Saline Aquifers
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-21)Diffusion of CO2 into water-based solutions generate an instability at the interface as a result of density differences. The rate of dissolution, the final saturation pressure and the mixing regime caused by convection ... -
Experimental Study on Automatic Evaluation of Drilling Fluid Properties
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)The drilling fluid has several important functions such as transporting cuttings out of the well and being a primary barrier during the drilling operation. When drilling challenging wells in the present and future, factors ... -
Experimental study on cuttings transportation in turbulent pipe flow
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Experimental investigation on cuttings transportation in turbulent flow, in both horizontal and inclined pipes were performed in the multiphase-laboratory at the University of Stavanger. Spherical glass particles were used ... -
Experimental study on parametric configurations of artificially downwelling aerations in stratified water
(Peer reviewed; Journal article, 2023)Downwelling aeration has become a widely applied approach to cope with the water eutrophication in stratified reservoirs, rivers and lakes. The aeration parameters involving flow rate, flow locations and working periodicity ... -
Experimental study on thermal effects on well components
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)The main objective of inflow control devices is to maintain a uniform inflow by providing an additional pressure loss between the formation and the wellbore. ICDs delay the production of water or gas, and thus increase the ... -
