Comparing mechanical and ultrasonic behaviour of a brittle and a ductile shale: Relevance to prediction of borehole stability and verification of shale barriers
(Peer reviewed; Journal article, 2019)Borehole collapse during drilling operations in shale formations is a well-known and costly problem within the petroleum industry. Recently it has become evident that shales may also form sealing barriers around the casing, ... -
Comparing Ray Trace and Fk-Modeling of the Refracted Wave Associated with Normal Mode
(Master thesis, 2011)An acoustic wave traveling through the water layer will, upon hitting the seafloor at the critical angle, generate a head wave traveling in the upper part of thesubsurface. While some of the energy is converted to this ... -
Comparison of drilling fluids (all types of drilling fluid like WBM, OBM and SBM) using in geothermal wells versus oil and gas HPHT wells (similarities and differences) during design, during operation and during connection. The comparison should take into consideration of the reason of using the mud in each category (wellbore stability, formation damage, pressure and temperature compatibility and tolerance, inhibitor compatibility, mud rheology, and etc.)
(Master thesis, 2022)Denne masteroppgaverapporten er skrevet med utgangspunkt i masterspesialiseringsprosjektet TPG4560. Noen av de teoretiske delene ble hentet fra fordypningsprosjektet og referansene ble lagt til de brukte delene. For å nå ... -
Comparison of continuous and discontinuous modelling for computational rock mechanics
(Dr. ingeniøravhandling, 0809-103X; 2002:149, Doctoral thesis, 2003)Computational rock mechanics becomes more and more popular. New programs are constantly under development, and the modelling process has become a natural part of the planning process for many caverns and tunnels, as well ... -
Comparison of Dry Gas Seasonal Storage with CO2 Storage and Re-Use Potential
(Master thesis, 2013)To make large-scale CO2 storage economic, many groups have proposed using CO2in EOR projects to create value for CO2 storage. However, CO2 EOR projectsgenerally require a large and variable supply of CO2 and consequently ... -
Comparison of existing performance prediction models for hard rock tunnel boring based on data collected at the Follo Line Project
(Master thesis, 2018)In Norwegian hard rock tunnelling history, drill and blast has mainly been the excavation method. At the Follo Line Project, which will be the longest railway tunnel in Scandinavia when it opens in 2021, tunnel boring ... -
Comparison of Gas Reservoir Performance from Simulation and General Material Balance
(Master thesis, 2014)The study of comparing gas reservoir performance using two different methods, namely numerical simulation and general material balance was conducted. The Songo Songo dry gas field in Tanzania was used for this study. The ... -
Comparison of Improved Oil Recovery Processes on the Norne Field, C-Segment
(Master thesis, 2015)The main task is to carry out a comparative simulation study for the polymer flooding, low saline water flooding and well location optimization; and then comparing their performance in terms of net present value. -
Comparison of methods for calculation of immature organic carbon values and initial hydrocarbon potential from mature organic carbon measurements
(Master thesis, 2016)In this study, five mass-balance-based (Peters et al., 1996; Jarvie et al., 2007; Jarvie, 2012) and curve-fitting methods (Banerjee et al., 1998; Dahl et al., 2004) are analysed that have been developed to determine the ... -
Comparison of practice for aggregate use in road construction — results from an international survey
(Chapter, 2017)Conventional flexible pavement structures are constructed using aggregates, in a combination of unbound and bitumen bound materials. Crushed rock aggregates are fundamental for road construction in many countries. This ... -
Comparison of single and mixed reagent systems for flotation of copper sulphides from Nussir ore
(Peer reviewed; Journal article, 2019)The present study investigates the application of thiol collectors and their mixtures on the flotation of copper-silver-gold minerals from a new copper mine located in northern Norway. The copper minerals (chalcopyrite, ... -
Completion Design Review with Focus on Well Integrity and Productivity
(Master thesis, 2012)In this thesis a full well design and detailed tubing design has been developed for the HPHT well K-14. Wellcat casing design software has been used for tubing string analysis. K-14 has been designed using the same ... -
Completion solutions and techniques optimized for RLWI: Identify problems and present alternative solutions
(Master thesis, 2010)RLWI is an important part of Statoil’s goal of increasing the recovery factor from subsea wells from 42% to 55%. Subsea well intervention has traditionally been performed by expensive workover rigs which have made intervention ... -
Compositional Features and Swelling Potential of Two Weak Rock Types Affecting Their Slake Durability
(Journal article, 2021)Weak and weathered rocks are well known for their sensitivity to changes in moisture content. Degrading behavior is common in weak rocks with moisture-sensitive mineral components and present numerous stability problems. ... -
Compositional gradient study in 4 North sea reservoirs
(Master thesis, 2011)In reservoirs with insignificant column heights, each component will have the same chemical potential regardless of its location. Therefore, the reservoir can be assumed to have a constant composition. On the other hand, ... -
Compositional Infrastructure based on Periodic Well Tests - Production Allocation for the Eagle Ford Field
(Master thesis, 2016)This study suggests a way of building an as-accurate-as-possible compositional infrastructure to generate continuous wellstreams, from periodic well tests. It also studies the influence of well test measurements on the ... -
