Design for operation and maintenance of the Johan Sverdrup oil and gas field
(Student paper, others, 2014-04)The Johan Sverdrup field was discovered in 2010, formed by three blocks (PL 501, PL 265 and PL 502) on the North Sea, with an estimated of reserves between 1.8 billion to 2.8 billion Barrels of Oil, so assessing the ... -
Design of a hypothetical relief well for a shallow reservoir, possible challenges.
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-05-09)Blowouts are one of the biggest threats during exploration and production of oil and gas. Losing control of a well can lead to severe consequences both economically, environmentally and put the working crew in danger. ... -
Designing Well Tests to Understand Performance of Induced Fractures
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Presently, more and more water injection wells operate under induced fracturing condition. Induced fractures geometry and their orientation with respect to the injection well and nearby production wells are crucial factors ... -
Detailed reservoir study of the Lower Jurassic Tilje Formation around the Noatun and Linnorm discoveries, Halten Terrace, Norwegian Sea
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-11-14)Tilje Formation in Halten Terrace is significantly affected by the strongly heterolithic nature of its component of lithofacies and the complicated reservoir architecture, which largely controlled by eustatic process of ... -
Developing a full field geological model with subsequent reservoir numerical simulation on the Krafla field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06)The Krafla field is newly discovered in production license PL 272/035 which is located in the North Sea where Statoil is the operator and Det Norske Oljeselskap is one of the partners. Exploration wells are drilled on the ... -
Development of a method to assess the steerability of different PDC bit designs from field data, and correlation with theoretical bit model
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The bit and directional tool are a part of the BHA system. This thesis work analyzes that part of the system. The objective of the thesis is to analyze the performance of different bit designs using a computer simulator ... -
Development of a Thermal Based Flow Measurement Technique for Very Low Flow Velocities
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)A measurement technique for very low flow velocities based on thermal measurements is proposed as an alternative for measurements in larger- diameter pipes. The velocity of a locally accelerated thermal flow is calculated ... -
Development of an improved Nanoparticle-modified Water Based Drilling Fluid
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)The objective was to improve conventional water based drilling fluid systems by the addition of nanoparticles. Experiments were conducted to evaluate whether addition of nanoparticles to the drilling fluid could improve ... -
