Parametric sensitivity studies of gravel packing
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-16)Several factors determine the success of Alpha-Beta gravel packing procedures in deviated wells. Among others gravel concentration, rheology of carrier fluid and injection rates could be mentioned. Choosing incorrect ... -
Particle settling in non-Newtonian drilling fluids
(PhD thesis UiS;80, Doctoral thesis, 2009-12-14)Particle settling is relevant for several aspects of drilling and completion operations, and is directly related to safety and operational efficiency. The primary function of particles added to drilling fluids is to ... -
Particle transport and hole cleaning in wells during drilling
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)The purpose of the thesis was to look at particles in different rheology to develop a methodology for measuring settling velocities in static systems. There was built a small-scale cell with an inner pipe and a discharge ... -
Performance analysis of gas lifted wells with injection pressure operated valves in the Ekofisk field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06)Gas lift design featuring several gas lift valves in a well is common in the industry. The sequence of valves in the tubing string allows for gradual well unloading and injection through the deepest valve (operating point). ... -
Performance of autonomous inflow control systems
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)The first passive Inflow Control Devices (ICDs), were introduced in the early 1990’s. Their task is to provide an additional choking effect in long reach horizontal wells and to eliminate heel-toe effect. There are several ... -
Performance optimized rig design
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-12)Increasing the number of wells drilled into a reservoir leaves less oil in the reservoir as well as exploration of new reservoirs demands to drill new wells. By increasing the efficiency of a drilling rig, more wells can ... -
Performing simulation study on drill string mechanics, Torque and Drag.
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In this thesis work, a simulation and monitoring study was carried based on operational data obtained from two wells. These are South Sangu-4 and Sangu-11, which are situated in block 16. From the study it was found out ... -
Permeability evolution of chalk under different stress states
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)This thesis reports the results obtained from triaxial tests on Kansas outcrop chalk flooded with inert NaCl brine. Permeability measurements are conducted at 50ºC under different stress states simulated by five test ... -
Permeability modeling of Lavrans field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Permeability has been calculated for three exploration wells from the “Smørbukk” field, from the mid – Norwegian Sea. Permeability from logs, cores and cross plots have been derived and compared with permeability from well ... -
Permo-Triassic and Post-Rift Halokinesis in the Norwegian-Danish Basin
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The area of investigation is located in the Norwegian sector of the Norwegian-Danish Basin (NDB) and covers an area of ~20,000 km2 between the Stavanger Platform and the Central Graben. This basin is a Late Permian rift-basin, ... -
Petrophysical characterization of the Lower Cretaceous clastic wedges in the northwestern Barents Sea
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The results of the petrophysical evaluation of four turbidite systems located along the flanks of the Hammerfest Basin, in the southwestern Barents Sea, are presented in this master thesis. These systems are the reservoir ... -
Play based evaluation of the eastern margin of Nordland Ridge, Norwegian Sea.
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The main objective of this study is produce a petroleum system evaluation of potential plays along the eastern margin of the Nordland Ridge. The area of study consists of two major tectonic structures; the Nordland Ridge ... -
Plug and abandonment operations and tool positioning
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)With aging oil fields, the Norwegian petroleum authorities are focusing on Plug and Abandonment (P&A) plans. Therefore efforts are being made, by relevant authorities, to improve standards and procedures for the P&A ... -
Plug and abandonment operations performed riserless using a light well intervention vessel
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-14)In a few years there will be a significant increase in wells that need to be permanently plugged and abandoned (PP&A). Statoil operates around 500 subsea wells on the Norwegian Continental Shelf (N.C.S), whilst there exist ... -
