A compressible two-phase model with pressure-dependent well-reservoir interaction
(Journal article; Peer reviewed, 2013)This paper deals with a two-phase compressible gas-liquid model relevant for modeling of gas-kick flow scenarios in oil wells. To make the model more realistic we include a natural pressure-dependent well-formation ... -
Analysis of borehole failure related to bedding plane
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Borehole instabilities during drilling are more common in shale formations than in most other rock formations. Shale make up more than 80% of sediments and rocks in siliciclastic environments and about three quarters of ... -
Analysis of packer forces in vertical wells and frictionless sail sections
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)New discoveries could represent challenges in many ways such as high pressures and high temperatures. The reservoir contains corrosive liquids that are being produced to the surface. Since the casing is expensive to replace, ... -
Application and design of passive inflow control devices on the Eni Goliat oil producer wells
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)During the recent years installation of ICD completions has become more common in new wells. ICDs have proven to be an operationally simple and reliable completion solution. The primary benefits of installing ICDs are ... -
Asymptotic behavior of a compressible two-phase model with well–formation interaction.
(Journal article; Peer reviewed, 2013-02)In this work we consider a compressible gas–liquid model with a well–reservoir interaction term that is relevant for coupled wellbore-reservoir flow systems involved in e.g. drilling operations. Main focus is on deriving ... -
Automated well control using MPD approach
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)The easy oil and gas is gone. Newly discovered fields follow the trend of being smaller and harder to reach, moving to increasingly remote locations with high temperatures. The huge fields of the past are maturing and ... -
Creep behavior and loading rate dependency of chalks
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)‘‘Mechanically high porosity chalks behave as frictional materials, but with an end-cap reflecting pore collapse failure, and the mechanical properties of chalk are strongly dependent on the type of fluid in the pores’’ ... -
Cretaceous-Cenozoic tectonostratigraphic evolution of the Loppa High

Cuttings transport in inclined and horizontal wellbore
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Efficient cuttings transport and hole cleaning is very important for obtaining an effective drilling operation. In inclined and horizontal drilling, hole cleaning issues is a common and complex problem. This thesis explores ... -
Deepwater drilling problems
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)Several problems encountered in the deepwater makes it very difficult in terms of accessibility for drilling. In this work, the major problems in the deepwater are identified, and discussed from different perspectives. ... -
Depleted reservoir drilling : a study of the Ula field in the North Sea
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Ula is an oil field operated by BP in the southern part of the Norwegian North Sea. As the field matures depleted intervals are drilled to access remaining reserves. Drilling in highly mature fields is challenging, both ... -
Drilling optimization : drill bit performance optimization using DROPS simulator ( Ekofisk/Eldfisk Field)
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Two drilled Wells: Well A and Well B were analysed under the following input data; drilling parameter, survey data, lithology data and bit information using DROPS simulator to showcase the bit performance optimization ... -
Drilling problems in depleted reservoirs
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)New oil and gas wells are becoming more challenging to drill. New technology and better understanding of new and existing reservoirs become available, pushing the envelope of what is technically possible and economically ... -
Dynamics of multiphase dispersed systems in rotating annulus
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)An investigation of multiphase dispersed system dynamics in rotating annulus is described. The investigation was based on measuring rheological constant (viscosity) of two-phase flowing system. The flow was obtained between ... -
Effect of core cleaning solvents on wettability restoration and oil recovery by spontaneous imbibition in surface reactive, low permeable limestone reservoir cores
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The success of oil recovery, by water flooding, in naturally fractured, low permeable limestone reservoirs strictly depends on imbibition of injected water into the reservoir matrix block. Prerequisite of imbibition process ... -
Effect of Various Silica Nanofluids: Reduction of Fines Migrations and Surface Modification of Berea Sandstone
(Journal article; Peer reviewed, 2017-11)Abstract: This work is aimed at addressing surface modification of berea sandstone by silica nanofluids (NFs). Three types of nanofluids were used: silica/deionized water (DIW), silica in DIW with a stabilizer fluid ... -
Effect of water flow in gravel pack with regards to heavy oil production
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The objective of the thesis is to see how the effect of water is displacing the oil through gravel pack. Experimental solutions have been developed for displacement performance of two vertical displacements and one horizontal. ... -
