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 ... -
Compositional Simulation of Tertiary Gas Injection Experiments - Investigating the Effects of Capillary Pressure
(Master thesis, 2018)Tertiary gas injection is an enhanced oil recovery method, which aims for reducing residual oil in a reservoir by gas injection. Tertiary gas injection induces a system of three-phase where water, oil and gas flow ... -

Concentration at the Minimum Bubble Velocity (CMV) for Various Types of Flotation Frothers
(Journal article; Peer reviewed, 2017)This paper presents the determination of a concentration at the minimum bubble velocity (CMV) for different types of frothers, such as straight and branched alkyl chain aliphatic alcohols, 1,ω-diols, poly(propylene glycol) ... -
Concentric Coiled Tubing Drilling System
(Master thesis, 2015)A concept review of concentric coiled tubing drilling (CTD) system is performed in this Master thesis, hereafter named DualCTD. The main purpose is to investigate and present the advantages, limitations and applications ... -
Conceptual models for rock burst and energy transformations in strain burst
(Chapter, 2020)The occurrence of a rock burst event depends on two requisites: the secondary stresses after rock excavation must be beyond the rock strength and there are excessive energy releases from the rock mass in addition to the ... -
Condensate Blockage - A study from the Norwegian Continental Shelf
(Master thesis, 2020)This Master Thesis is a continuation of the work done in the specialization project TPG4560 in the fall of 2019. Some parts are directly taken from the report “PVT Analysis for Condensate Blockage – A study of gas condensate ... -
Condition monitoring system for all-electric subsea systems
(Master thesis, 2023)I dag er de fleste subsea systemene utviklet med elektro- hydrauliske kontrollsystemer. Dette systemet har i mange tiår blitt utviklet til det velfungerende og pålitelige systemet det er i dag. I disse systemene kommuniserer ... -
Constrained AVO for CO2 storage monitoring at Sleipner
(Journal article; Peer reviewed, 2017)A feasibility study of inverting for CO2 elastic properties using a model based AVO inversion is carried out. We use principal component analysis on a set of PP reflection coefficients to calculate an optimal basis function ... -
Contact Angles in Two-Phase Flow Images
(Peer reviewed; Journal article, 2020)In this work, we calculate contact angles in X-ray tomography images of two-phase flow in order to investigate the wettability. Triangulated surfaces, generated using the images, are smoothed to calculate the contact angles. ... -
Continental weathering and recovery from ocean nutrient stress during the Early Triassic Biotic Crisis
(Peer reviewed; Journal article, 2022)Following the latest Permian extinction ∼252 million years ago, normal marine and terrestrial ecosystems did not recover for another 5-9 million years. The driver(s) for the Early Triassic biotic crisis, marked by high ... -
Contribution of Rock Physics Laboratory Tests and Modelling to Improving Uplift Estimates
(Journal article; Peer reviewed, 2018)Most currently applied procedures for uplift estimation rely on assumptions that porosity and seismic / log measured velocity are unaltered by the uplift process. Laboratory experiments have been performed with synthetic ...
