Performance optimized rig design
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-12)Increasing the number of wells drilled into a reservoir leaves less oil in the reservoir as well as exploration of new reservoirs demands to drill new wells. By increasing the efficiency of a drilling rig, more wells can ... -
Performance-based policy in offender rehabilitation: Limitation or innovation for frontline workers in Liaison and Diversion services?
(Peer reviewed; Journal article, 2020-06)In recent years, the English government has been using competitive elements in the process of allocating public funds through policy. Front-line workers struggle with the limitations imposed by such a model. A qualitative ... -
The Performances of Three Commercially Available Assays for the Detection of SARS‐CoV‐2 Antibodies at Different Time Points Following SARS‐CoV‐2 Infection
(Peer reviewed; Journal article, 2022)The aim of this study was to evaluate the performances of three commercially available antibody assays for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies at different time points ... -
Performative kunstdidaktiske erfaringer som praksisrefleksjon
(Peer reviewed; Journal article, 2021-09)Hensikten med denne studien er å undersøke hva performative kunstdidaktiske erfaringer kan tilføre praksisrefleksjonen til PPU (praktisk pedagogisk utdanning) studenter i drama og teater. Forfatterne har gjennomført tre ... -
Performing Rurality in Online Community Groups*
(Peer reviewed; Journal article, 2022-03)In this paper, we investigate how rurality is performed in online community groups, attending in particular to outdoor recreation and engagement with local nature. The starting point for our performative approach is that ... -
Performing simulation study on drill string mechanics, Torque and Drag.
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In this thesis work, a simulation and monitoring study was carried based on operational data obtained from two wells. These are South Sangu-4 and Sangu-11, which are situated in block 16. From the study it was found out ... -
Periodic CO2 Injection for Improved Storage Capacity and Pressure Management under Intermittent CO2 Supply
(Peer reviewed; Journal article, 2022-01)Storing CO2 in geological formations is an important component of reducing greenhouse gases emissions. The Carbon Capture and Storage (CCS) industry is now in its establishing phase, and if successful, massive storage ... -
Perish or prosper: Trade patterns for highly perishable seafood products
(Peer reviewed; Journal article, 2021-05)In recent years trade with highly perishable agricultural products like fresh fish, berries, and cut flowers has increased substantially. The perishability of these products appears to challenge conventional wisdom when ... -
Permanent Plug & Abandonment Decision Support Technique: Modelling and Simulation based Analysis for Enhanced Value
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06)Several oil and gas producing assets on the NCS (Norwegian Continental Shelf) are entering a phase where the costs of extracting the hydrocarbons from the reservoir exceeds the income generated from production, and thus ... -
Permanent plug and abandonment on Gyda field, challenges, solutions, and qualification of creeping formation to be used as a well barrier in Gyda
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-14)Well plugging and abandonment (P&A) presents a very substantial challenge to oil and gas operators, and this challenge will increase exponentially in the coming decades. P&A operation cost the operators billions of dollars ... -
Permanent Plugging and Abandonment - An identification and discussion of technologies and the differences in UKCS and NCS regulations
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06)There is a large number of wells on the Norwegian Continental Shelf that need to be permanently plugged and abandoned (P&A) within the next decades. As P&A does not provide any income, it is very important to develop ... -
Permeability evolution in chalk linked to stress and thermochemical aspects of North Sea reservoir conditions
(PhD thesis UiS;564, Doctoral thesis, 2020-12)The project was initiated by The National IOR Centre of Norway within the University of Stavanger and it aligns with the overall goal of the centre to improve oil recovery on the Norwegian Continental Shelf. It contributes ... -
Permeability evolution of chalk under different stress states
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)This thesis reports the results obtained from triaxial tests on Kansas outcrop chalk flooded with inert NaCl brine. Permeability measurements are conducted at 50ºC under different stress states simulated by five test ... -
Permeability evolution of shear failing chalk cores under thermochemical influence
(Peer reviewed; Journal article, 2020-04)Development of petroleum reservoirs, including primary depletion of the pore pressure and repressurization during water injection naturally, leads to changes in effective stresses of the formations. These changes impose ... -
Permeability modeling of Lavrans field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Permeability has been calculated for three exploration wells from the “Smørbukk” field, from the mid – Norwegian Sea. Permeability from logs, cores and cross plots have been derived and compared with permeability from well ... -
Permeability of Cement Plugs In Steel Pipes and Effects of Treatment Material Injection
(Bachelor thesis, 2021)Wellbore integrity is a common challenge in the oil and gas industry. Despite all measures in place, the integrity is often threatened. The integrity of the well is dependent on zonal isolation, effort is made to ensure ... -
