Application of a bayesian framework to decision making regarding maintenance and intervention of subsea water injection pumps
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)As more and more oil fields in the North Sea are developed as subsea fields, the monitoring and maintenance availability is becoming difficult to perform on the equipment used for subsea boosting. Often maintenance is ... -
Borehole stability on Yme
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The main object of this thesis it to perform an in-situ stress and borehole stability evaluation of the wells in the Yme field. The Inversion technique was used find the maximum and minimum horizontal stresses. The ... -
Enhanced oil recovery in limestone. Chemical effects of seawater injection on the rock surface at different temperatures
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The fluid location, flow and distribution in a reservoir rock are to a large extent governed by the wetting condition of the rock. These factors influence oil and gas production, water flood recovery and the performance ... -
Gas in overburden on Ekofisk
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The Ekofisk field is a large producing oil and gas field located in the southern part of the Norwegian sector of the North Sea. The production started in 1971. During the production, the reservoir has been decompressed ... -
Feasibility studies of combining drilling with casing and expandable casing
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)Nowadays, the biggest challenges in the oil business are the cost of operations versus the sizes of the prospect. We are drilling smaller targets and over the last few years, rig cost, service company rates and materials ... -
Optimization of gas lift system in Varg field
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)The objective of this thesis work is to obtain the optimum gas injection rate which yields the maximum oil production. Obtaining the optimum gas injection rate is important because excessive gas injection rate reduces oil ... -
Study of CO2 properties and transportation for injection well into reservoir
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)One of the possible solutions to reduce CO2 emission in atmosphere is to inject for storage in reservoir. This action is known as the residual gas geological storage project. One of the important aspects in this project ... -
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 ... -
Seismic characterization of fault zones for use in fault facies reservoir models
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009) -
Evaluation of artificial lift methods on the Gyda field
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)Since a production peak in 1995 the oil production on the Gyda field has decreased. Water cut is increasing and reservoir pressure is decreasing. This thesis is a study of the artificial lift methods being evaluated to ... -
Through tubing rotary managed pressure drilling
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)Managed pressure drilling (MPD) has been known to the industry for a few years. MPD with the ability of coping with risky down-hole pressure situations has gained a great deal of attention. Compared to MPD, the drilling ... -
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 ... -

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. ... -
Real time production monitoring with prediction and validation
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)This Master of Science studies Optimum Online’s real time estimated production at the Ekofisk Field. Information from offshore process sensors are used to validate the individual well estimates and to detect any deviation ... -
Cretaceous-Cenozoic tectonostratigraphic evolution of the Loppa High

Evaluation of the primary cement operation on the production casing in the Ekofisk field and the Eldfisk field
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The foremost goal of primary cementing is to provide zonal isolation in a well. Cementing of the casing/liner set right above the reservoir on the Ekofisk and Eldfisk fields are associated with a lot of challenges. ... -
Use of expandable pipe technology to improve well completions
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The underlying concept of expandable technology is cold‐working a pipe downhole to the required size. An expansion cone is typically used to permanently deform the pipe downhole. The cone is pulled or pushed through the ... -
Calculation of forces acting on a rotary steerable liner drilling system
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)Torque and drag calculations performed on a new liner drilling design indicate that a very high grade drillpipe, up to S-135, is required in order to satisfy the requirements which both axial and torsional loading place ... -
