A novel solution for plugging of subsea wells
(Master thesis, 2016)In recent years, Statoil and other operators on the Norwegian continental shelf (NCS) have publicly announced the need for innovation and new solutions that can improve the efficiency, and reduce the cost of plugging and ... -
A novel wellbore strengthening method by using rotary jet while drilling
(Journal article, 2020)Lost circulation is one of the most common and costly problems in drilling operations. Improving the wellbore strengthening by plugging drilling induced fractures using rotary jet method is a novel and effective method to ... -
Numerical analysis of mixed-mode rupture propagation of faults in reservoir-caprock system in CO2 storage
(Journal article, 2018)Injection-induced seismicity and caprock integrity are among the most important concerns in CO2 storage operations. Understanding and minimizing fault/fracture reactivation in the first place, and rupture growth/propagation ... -
Numerical analysis of stresses and displacements for the Tafjord slide, Norway
(Journal article; Peer reviewed, 2006)Numerical modelling has been used for analyzing stresses and displacements for the very steep and more than 1,000 m high Heggura rock slope near Tafjord, Norway where a disastrous 3 million m3 rock slide occurred in 1934. ... -
Numerical Modeling and History Matching of Super-Wet Combustion Tube Test
(Master thesis, 2014)A number of laboratory experiments are defined and implemented to reveal the in situ combustion behavior on core samples drilled from heavy oil reservoirs under specifically designed conditions. The accelerating rate ... -
Numerical modeling of direct shear tests of rock joints
(Master thesis, 2023)Numerisk modellering spiller en stadig større rolle i felt innenfor ingeniørgeologi. For modelleringens bruk i forskning knyttet til konkrete aspekter for bergmekanikk, er sprekkdeformasjon når utsatt for normal- og ... -
Numerical modeling of fracture initiation using plasticity models
(Master thesis, 2018)Nowadays hydraulic fracturing is a key part of the oil and gas industry to enhance the field's production. Therefore, is important to understand how fractures initiate and how to extract important information from them for ... -
Numerical Modeling of Radial Fracturing of Cement Sheath Caused by Pressure Tests
(Chapter, 2019)To achieve an acceptable level of zonal isolation, well integrity should be guaranteed in hydrocarbon production and geological CO2 sequestration. Well pressure test can cause different types of failures in the well system ... -
