(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)In the present investigation, the disturbance and its effect on the bottom hole pressure has been studied. After digging into the prior works, it’s figured out that the reason of their failure is oversimplification and ... -
Manufacturing Software Prototype for applying fuzzy MCDM in Well completion optimization
(Master thesis, 2021)Well completion is the important system to put the well into the production phase. This well completion engineering system is complex engineering which requires reservoir drilling, cementing of the well, installation of ... -
Material behavior of perforated and non-perforated simply supported steel plates in air and water, subjected to impact loads.
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-12)Due to challenging economic times, industries such as oil and gas face the need of moving from customized, time-consuming, and costly solutions, to more standardized technologies, to reduce costs and maintain high profits. ... -
Materials for Well Integrity: Performance of Setting Materials for Well Cementing Operation
(PhD thesis UiS;642, Doctoral thesis, 2022-05)Primary cementing operation is the process of pumping and placing a cementitious slurry in a well. After setting, the so-called barrier material has to provide zonal isolation in the annular gap behind casing string. After ... -
Mathematical and Numerical Modelling of Lithium Battery
(Master thesis, 2021)Application of lithium-ion batteries have increased in recent years due to their high energy density, low weight and smaller form factor. Machine learning algorithms are used in lithium-ion battery management systems due ... -
Mathematical modeling of cancer cell migration - from in vitro to in vivo
(PhD thesis UiS;511, Doctoral thesis, 2020-05)Tumors has been the object of computational model studies for nearly five decades. The early models considered simple tumor growth based on nutrients, whereas models now can simulate from microscale gene expressions in ... -
Mathematical modeling of compressible and incompressible multiphase flow based on mixture theory
(PhD thesis UiS;501, Doctoral thesis, 2020-11)MIXTURE THEORY has been developed based on balance laws and conservation principles which is well known in continuum mechanics, and has been widely applied to systems which can be characterized as a mixture of interacting ... -
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 ... -
