Effect of Nano Additives on Friction in a Bentonite Water Based System
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-13)This thesis will present relevant literature study and theory for the experimental and simulation parts. Several water based drilling fluids containing high and low concentrations of TiN, MoS2 and Graphene in nano-size ... -
Evaluation of kick and loss scenarios in experimental lab facility
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Detection and evaluation of gain and loss situations is crucial for safety during drilling operations. During managed pressure drilling there is higher risk of kicks than during traditional drilling. Early stage detection ... -
Evaluation of Measurement-While-Drilling, telemetry methods and integration of control systems
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)This paper will present an overview of the applications of the measurements performed by the Measurement-While-Drilling and Logging-While-Drilling tools. An evaluation of the available telemetry techniques used to transfer ... -
Extended Reach Drilling on the example of Reelwell Drilling Method: Influence examination of different drill pipes on drilling performance on Idun field on the Norwegian Continental Shelf by PGNiG Norway AS.
(Master thesis, 2011)Horizontal or extended reach drilling is incredibly fast growing technology. Although in some areas of the world ERD is still novelty, most of oil companies have been using the technology reliably and successfully for ... -
Impact of Well Configuration on CO2 Injection for Energy Exploitation in Geothermal/Geopressured Reservoirs
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Injecting dissolved CO2 into deep saline aquifers is one of the more promising methods of alleviating greenhouse gas emissions. By simultaneously extracting the geothermally-heated brine in the aquifer, there is an opportunity ... -
Investigation of Leakage Paths in Well Abandonment
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)A large number of wells will have to be abandoned at the NCS and around the world. NORSOK D-010 states that a well that is permanently abandoned shall be abandoned with an eternal perspective and with zero leakage [1]. ... -
Reliability Based Casing Design
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)It is a well-known fact that wells are increasingly becoming extremely expensive and difficult to drill as well as develop due to increasing water depth, temperatures, and pressures. All these result in an increasing load ... -
Sand Control Selection in HPHT Reservoirs
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-07)High Pressure High Temperature (HPHT) reservoirs have shown to have great potential of oil and gas reserves through industrial experience. Norwegian Continental Shelf has such good potential HPHT reservoirs. But, HPHT ... -
Simulations of the inner heat coefficient during methane hydrate formation and growth in a stirred cell reactor
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)In the thesis presented in this paper, simulations have been performed in order to investigate the inner heat coefficient of a hydrate-testing cell as a function of varying stirring rates, initial water amounts, and testing ... -
Study of Slug Flow in Undulated Horizontal Wells
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Terrain induced slugging have become more common as the petroleum industry matures. Late-life fields, deepwater fields and marginal subsea tiebacks to existing facilities are prone to terrain induced slugging. Extended ... -
The use of alternative materials for drill pipe to extend drilling reach in shallow reservoirs
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)One of the limiting factors for extended reach and horizontal drilling is high torque and drag values. One way to reduce torque & drag is to reduce the weight of the drill pipe by exchanging the standard steel with other ... -
The value of drilling optimization
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The well construction time and cost on the Norwegian Continental Shelf has increased drastically since 2001. The production is declining and there is a strong need to bring more wells on production while at the same time ... -
Time Estimation of Future Plug and Abandonment Operation at Brage Field
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Production of oil on the Norwegian continental shelf started in the early 70’s. Many of these fields are now reaching the end of their production time. The industry is now awaiting a “plug wave” in the not too distant ... -
Torque & drag analyses of North Sea Wells using new 3D model.
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Excessive drill string torque and drag is one of the major limitations of extended-reach and horizontal drilling. The torque and drag models are used in the planning phase and during the drilling of a well, as a tool used ... -
Utilizing down hole data, acquired by a multiple sensor down hole tool, to determine the PDC bit wear state.
(Masteroppgave/UIS-TN-IPT/2008;, Master thesis, 2008)By using real-time data from INTEQ`s CoPilot Real-Time Drilling Optimalization a search for dependable indications of the degree of the bit wear was done. This would improve decision making procedures for when to pull the ... -
Wellbore stability and rock mechanics study on the Ula field
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-20)In the years to come more challenging drilling conditions will occur when the last reserves need to be collected. More directional drilling will be used and good wellbore conditions will be necessary to make this possible. ...
