Prediction efficiency of immiscible Water Alternating Gas Performance by LSSVM-PSO algorithms
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020)In this work the aim is developing LSSVM-PSO model capable of capturing the interplay between the most influential parameters (mechanisms) and recovery factor (RF) of WAG process in layered reservoirs. In a previous work ... -
Prediction of mechanical friction forces on casing being run
(Bachelor thesis, 2023)In recent years, advancements in drilling technology have led to increasingly complex wellbore trajectories, particularly in the case of horizontal wells and extended reach wells (ERWs). This complexity necessitates highly ... -
Predictive accuracy of data-driven solutions to the transient response of the drilling system
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)One of the utmost desires of the drilling industry is full drilling automation to minimize well construction cost, optimize well performance and many other advantages. Dynamical system modeling and control of complex systems ... -
Prevention of loss of drilling fluids and formation damage when drilling through high permeability formations
(Bachelor thesis, 2023)In order to avoid kicks and the potential for a well blowout, it is necessary to maintain the drilling fluid pressure above the pore pressure of the formation. However, doing so may result in fluid loss due to the fluid ... -
Probabilistic Portfolio Modeling in Python
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-14)The portfolio selection problem has been known for centuries. However, Markowitz (1952) was the first to introduce a robust framework for optimized portfolios on financial markets. Later this approach was applied in the ... -

Pump pressure manipulation during MPD connection
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-14)Over time the remaining oil prospects are becoming harder to drill and managed pressure drilling is a tool that can be used to reach target depth in depleted reservoirs or similar narrow margin scenarios. In any narrow ... -
Qualification of the Cementitious Material Rock-based Geopolymer in Permanent Plug & Abandonment
(Master thesis, 2022)When an oil & gas well proves not to be economically favourable anymore, or is technically inviable, the well has served its life and are due to be shut-down and sealed, also referred to as permanent plug & abandonment. ... -
Reactive flow in chalk at reservoir temperature – Experiment and simulation
(Bachelor thesis, 2021)This thesis seeks to study how 0.219 M MgCl2 brine flooded through chalk cores at reservoir temperatures will chemically react when flooded through at various flowrates. We used two different chalk cores. The cores were ... -
