A Study of the Effect of Pressure and Temperature on the Mechanical Friction of Four Different Fluids Using a Specially Designed Setup
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)The mechanical friction caused by the contact between the rotating drillstring and the borehole or casing can lead to significant challenges such as excessive torque and drag, limitation in running speed of drillstring and ... -
An experimental study of unsupported pipe buckling in live well intervention
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)In this experimental study, unsupported pipe experiments are conducted. Information regarding intervention operation, focusing on snubbing operations in live well interventions and unsupported buckling during these operations, ... -
An Overview and Discussion of MPD Systems used in Offshore Operations
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Globally, established fields are reaching maturity and easily accessible reserves have already been exploited. The remaining reserves are generally more difficult to drill and attempting to drill them using conventional ... -
Application of Multilateral Wells as an alternative solution for costs optimization
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Field completion techniques have progressed over the last twenty years. Today, different methods of well drilling can reduce total costs spent on single well construction. Multilateral wells is the primary example of ... -
Controlling Pumpability of Geopolymers for Downhole Placement
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-14)Ordinary Portland cement (OPC) is the prime material used to manufacture concrete and as a barrier material in well construction. Cement has its own advantages such as pumpability, setting, bonding to steel and formation, ... -
Experimental study on thermal effects on well components
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)The main objective of inflow control devices is to maintain a uniform inflow by providing an additional pressure loss between the formation and the wellbore. ICDs delay the production of water or gas, and thus increase the ... -
FEM Modelling and Simulation of Production Casing with Local Wear Damage
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)Field data show that casing and production tubing experiences wear on both the internal and external parts of the tubular. The main mechanisms of the wear are the mechanical friction between drill string and casing, ... -
Influence of measured thermophysical parameters of drilling fluids on downhole temperature models
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-29)Predicting downhole circulating temperature is essential for successful drilling operations as bottom hole temperature variations are a major cause of changing effective mud density and mud volume. So, the effort is needed ... -
New Drilling Technology for Hole Cleaning and Efficient Drilling
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-07)Well integrity is an important safety aspect of a well. Lack of wellbore integrity can lead to challenges like wellbore collapse, stuck pipe, lost circulation and sloughing shales, which are all big problems for drillers. ... -
Numerical simulation of temperature-dependent flow dynamics in drilling operations
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)This thesis is a description of the research and improvements on solving hyperbolic conservation laws by defining a hybrid explicit/implicit numerical scheme. Former researches have been done by (Evje and Flåtten 2005) on ... -
Potential Utilization of Settled Barite as Permanent Barrier Material
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-14)The focus on permanent Plug and Abandonment (P&A) has increased the last few years, due to aging infrastructure of many of the fields on the Norwegian Continental Shelf (NCS). Permanent P&A introduces significant expenses ... -
Reliability-Based Casing Design with Focus on an APB Collapse Scenario
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)In times of unstable oil price, optimization related to casing and tubing design becomes more important than ever. Reducing cost and at the same time ensuring reliable and safe drilling and completion installations becomes ... -
The Physics of Buoyancy, Effective Tension and Pinching-off Effect
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-13)The thesis addresses at the beginning the understanding of the development of forces that result in buoyancy, and the concept of effective forces. Then, it continues more in-depth with an application of effective forces ... -
Well Design With an Environmental Focus
(Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-08)The decisions made during well planning have mainly been focused on safety, cost efficiency and applicability of the design. As the climate have been getting more attention the past years, environment is now high up on the ... -
