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 ... -
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 ... -
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 ... -
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’’ ... -
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 ... -
The use of sea water tracer as a tool for history matching of the Statfjord Fm simulation model
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)In this study, the Statfjord Fm reservoir simulation model was set up to track injected sea water. The sea water itself thereby forms a tracer in the simulation model. This sea water tracer was included with the intent ... -
Wettability alteration in carbonates : the effect of water-soluble acids in crude oil and application of enzyme for wettability alteration
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The objective of the project is defined in two phases. The first phase is to study the effect of oil composition and carboxylic acids in the crude oil on the wetting condition and wettability alteration process using ... -
Experimental study of low salinity EOR effects from the Varg field
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)The extra oil recovery obtained when flooding a sandstone reservoir with low saline water is called low salinity (LowSal) effect. The term salinity refers to amount (and type) of salt that makes up the ionic composition ... -
Mathematical modeling of water-rock chemistry during water injection and its impact on the composition and porosity of chalk

Hole cleaning and hydraulics
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Cuttings transport and efficient hole cleaning remains a vital challenge when planning and drilling vertical, deviated, high angle and extended reach wells. Optimization of cuttings transport depends on so many factors- ... -
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 ... -
Evaluation of experimental methods to determine wettability
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Two methods to evaluate the wettability of carbonates have been investigated: Aqueous cationic surfactant solutions contact angles on oil-wet calcite crystals, and imbibition time of surfactant drops into oil-wet ... -
Evaluation of a method of placing cross-sectional barriers during permanent plugging of wells
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)When oil and gas wells reach the end of their production life, they need to be permanently plugged and abandoned. The requirements for a permanent barrier state that it must cover the entire cross-section of the wellbore, ... -
Numerical simulation of surfactant flooding in mixed wet reservoirs
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Surfactants have been considered for enhanced oil recovery either by reduction of oil–water interfacial tension (IFT) or through wettability alteration. This study reveals the effect that reduced interfacial tension has ... -
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, ... -
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 ... -
