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 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 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, ... -
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 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 ... -
Exploring the behaviour of Silicon by empirical analysis of galvanostatic charge-discharge curves
(PhD Theses;, Doctoral thesis, 2024)The capability of battery materials to deliver not only high lithium (Li) storage capacity, but also the ability to operate at high charge/discharge rates is an essential property for development of new batteries. First, ... -
FAITH AND MOBILITY OF HYDROGEN IN GEOLOGICAL POROUS MEDIA
(Master thesis, 2022)Large-scale hydrogen storage can help alleviate the main drawbacks of renewable energy generation, their intermittency, and their seasonal and geographical constraints. Renewable energy without energy storage is unable to ... -
The fate of hydrocarbon leaks from plugged and abandoned wells by means of natural seepages
(Peer reviewed; Journal article, 2020-10)When a well reaches the end of its productive life, it is permanently plugged and abandoned. Even though new technology and verification methods are being evaluated, it is evident that operational, barrier material and ... -
FEM Modelling and Simulation of Production Casing with Local Wear Damage
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Field data show that casing and production tubing experiences wear on both the internal and external parts of the tubular. The main mechanisms of the wear are the mechanical friction between drill string and casing, ... -
Field Case Study of Drill Bit Performance Analysis in Valhall Flank West
(Master thesis, 2021)This thesis will present relevant literature study, data quality assertion and performance evaluation and economic considerations based on field data from Valhall Flank West. The aim is to investigate, explain and suggest ... -
FIELD-SCALE GENERALITY OF THE MACHINE LEARNING MODELS
(Master thesis, 2022)Drilling performance is directly related to fundamental aspects such as drilling variables that can affect the performance of the operation, the well stability, efficiency of drilling equipment, use of new technologies and ... -
