Mathematical Modelling of the Drilling Process for Real-time Applications in Drilling Simulation, Interpretation and Assistance
(PhD thesis UiS;, no.;506, Doctoral thesis, 2019)For the last thirty years, mathematical modelling has been used to develop software solutions that support drilling engineering activities at the planning stage of drilling operations. But it is only for the last decade ... -
Measurement and Control in a Flow Loop System
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-13)Automation of processes is key to perfecting them. Several systems exist in order to simply this process, although they may be simple to use most are however, expensive to acquire. This thesis attempts to program an Arduino ... -
Measurement of Viscosities and Friction Pressures in Non-Newtonian Fluids
(Bachelor thesis, 2021)The purpose of this bachelor project is to investigate the correlation between friction pressure predictions inferred from rheometer measurements and actual friction pressures in a pipe. A modular pipe flow loop is designed ... -
Measuring filter-cake cohesive strength and flowability
(Peer reviewed; Journal article, 2022)The filter-cake has a critical role in temporarily reducing the permeability of the wellbore to prevent issues such as lost circulation, formation damage, wellbore collapse and differential sticking. The filter-cake's ... -
Measuring the Magnetic Content of Drilling Fluid
(Master thesis, 2021)Magnetic contamination of drilling fluid can impact the accuracy of the directional surveying by shielding the magnetic field. Additionally, this contamination, such as swarf or finer magnetic particles, can agglomerate ... -
Mechanical Earth Modelling (MEM) and Well Design for High Pressure High Temperature Fields
(Master thesis, 2022)Conventional reservoirs are being depleted and attention has been given to more demanding conditions, like high pressure high temperature (HPHT) environments or under salt formations. There are, however, limited documents ... -
Methane–propane hydrate formation and memory effect study with a reaction kinetics model
(Peer reviewed; Journal article, 2020-05)Although natural gas hydrates and hydrate exploration have been extensively studied for decades, the reaction kinetics and nucleation mechanism of hydrate formation is not fully understood. In its early stage, gas hydrate ... -
A method for assessing drilling fluid induced formation damage in permeable formations using ceramic discs
(Peer reviewed; Journal article, 2022)When drilling an oil and gas or geothermal well, the formation's ability to produce or flow may be reduced because of exposure to the drilling fluid during the drilling operation. To evaluate such formation damage, core ... -
Method for reconstruction of axisymmetric capillary wave surface topography using inverse ray-tracing of refracted laser sheet
(Peer reviewed; Journal article, 2022)Capillary waves can be used to measure the fundamental fluid properties such as surface tension as well as, potentially, the viscosity of Newtonian fluids. This requires the measurement of various wave parameters, mainly ... -
Mineral replacement in long-term flooded porous carbonate rocks
(Peer reviewed; Journal article, 2019-09)This study reports mineralogical and physical property changes linked to geo-chemical alterations processes during three ultra-long-term tri-axial tests on outcrop-chalk from Liège (Belgium). The test core plugs were flooded ... -
Miscible CO2 flooding for EOR in the presence of natural gas components in displacing and displaced fluids
(Journal article; Peer reviewed, 2018-02)Carbon dioxide (CO2) flooding is a complicated process as it involves phase behavior. The objective of this work was to understand the mass transfer mechanisms during flooding with CO2 and CO2/C1/C3 (CO2/HC) based on ... -
