A Review of Sustained Casing Pressure in Offshore Wells - Mechanisms, Diagnosis and Remediation
Langelo, Even (Bachelor thesis, 2021)Sustained casing pressure (SCP) has in the later years received increased attention. SCP is the result of gas migration through failed or degraded well barriers manifesting at the wellhead as annular pressures that cannot ... -
An experimental research of Newtonian fluids inan annular Heavy-Over-Light fluid displacement
Bratten, Sveinung Huglen (Bachelor thesis, 2021)During the construction of a well, casings are considered essential for the wellintegrity. The job of securing the casing in place, i.e. the primary cementingof the casing, is a challenging task in itself due to the vast ... -
An Experimental Study of Fluid Displacements and Effects of Inner Pipe Vibration in an Eccentric and Vertical Annulus
Leknes, Magnus (Master thesis, 2021)Well abandonment operations can be expensive and time consuming, and thousands of wells will need to be permanently plugged and abandoned off the coast of Norway in the coming years. One potential cost-cutting measure ... -
An Experimental Study of Vibration Assisted Displacement in a Horizontal Annulus for Enabling Through Tubing Abandonment
Fredheim, Fiona Øijordsbakken (Master thesis, 2021)Traditionally, Permanent Plug and Abandonment (PP&A) operations has been carried out by pulling casing and tubing using either Mobil Offshore Drilling Unit (MODU) or Fixed Platform Drilling (FPD). The costs can run up to ... -
An Experimental Study of “Heavy over Light” Density-Unstable Displacement of Newtonian Fluids in a Vertical Annular Geometry of Interest to Reverse Circulation Cementing
Bjørlo, Sjur Haugen (Master thesis, 2021)When an oil well is constructed it is important to cement the casing in place.The cement’s main objectives is to support the casing and ensure zonal isola-tion to prevent leakage of reservoir fluids to the surface. Primary ... -
Challenges associated with mercury occurrence on the Norwegian Continental Shelf
Ryningen, Gro (Master thesis, 2023)The thesis includes a review of the heavy metal mercury, with focus on its origin, effect on the environment, and its role in the petroleum industry. Mercury emissions from the petroleum industry in Norway is looked into ... -
Effect of scaling and mixing procedure on cement slurry and hardened cement
Søyland, Heidi (Master thesis, 2022) -
An Experimental Study of the Enhanced Mass Transfer Process by CO2 Absorption for Carbon Storage in Saline Aquifers
Hansen, Tamara (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-21)Diffusion of CO2 into water-based solutions generate an instability at the interface as a result of density differences. The rate of dissolution, the final saturation pressure and the mixing regime caused by convection ... -
Forstå og håndtere utfordringer knyttet til sandkontroll for utvinning av olje
Skaugen, Magnus (Bachelor thesis, 2023)In the petroleum industry, sand production is a prominent technical and economic challenge that may lead to severe implications such as well abandonment and casing erosion. This challenge is particularly pronounced in ... -
Measurement of Viscosities and Friction Pressures in Non-Newtonian Fluids
Rahimi, Nora Nafiseh (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 ... -
Permeability of Cement Plugs In Steel Pipes and Effects of Treatment Material Injection
Høie, Christian (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 ... -
Prediction of mechanical friction forces on casing being run
Larsen, Edward (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 ... -
Small scale thermohaline ocean circulation
Wanyenze, Joan Shanita (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)Upon examining the how convective flows are generated in the ocean, Henry Stommel presented a simple idealized model called the Stommel model (1961) to better understand how salinity and temperature differences can affect ... -
Undersøking av egenskapene til Polyanionisk Cellulose blandet med vann som sirkulerer gjennom en strømningssløyfe
Ryningen, Gro. (Bachelor thesis, 2021)Denne oppgaven er strukturert i to hoveddeler. Den første delen omhandler noen fundamentale roller borevæske har under boring. Det er i hovedsak fokusert på sirkulasjonssystemet i en boreoperasjon, hovedegenskapene til ... -
Wellbore stability analysis for an extended-reach well on Ekofisk
Diaz Lopez, Jairo Alexander (Master thesis, 2022)
