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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
The influence of pore pressure on rock-fluid interaction
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)The experimental work in this thesis was performed at the chalk laboratory in University of Stavanger. The main objective is to determine the overall influence of pore pressure on the mechanical strength of chalk in the ... -
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. ... -
Evaluation of Foam Cementing the Reservoir Liner in Deviated Wells on the Ekofisk M Platform
(Masteroppgave/UIS-TN-IPT/2009;, Master thesis, 2009)Foam cementing the reservoir liner has proven to be a good solution for achieving zonal isolation due to its low permeability and high compressive strength. However, out of the 32 reservoir liners cemented on the Ekofisk ... -
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 ... -
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 ... -
