P&A - status on regulations and technology, and identification of potential improvements
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-12)There will be a wave of wells needing to be abandoned in the North Sea over the next decades. The abandonment operation is known as Plug and Abandonment, or just P&A. As P&A has no value creation, it is very important that ... -
P&A in Arctic conditons
(Master thesis, 2014-06-30)All oil and gas wells will require plugging and abandonment (p&a) at some point in their operating life. Considering the challenging nature of the Arctic weather, its remoteness and lack of infrastructures, and its ice ... -
P&A of Valhall DP wells
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The original platforms on the Valhall field will have to be decommissioned due to integrity issues. The oldest drilling platform, Valhall DP, has 30 wells that must be P&A in order to remove the platform. This thesis ... -
P&A operations today and improvement potential
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-05-29)Today rig/derrick and vessels is traditionally used to perform a P&A operation. With a rising need for P&A operations combined with the wish of having a stable level of drilling operations, a shortage of rigs will be a ... -
P&A using PWC technique and verification of the plug
(Master thesis, 2014-06-16)When a well is permanently plugged and abandoned (P&A), a plug has to be set over the entire cross section of the well. The conventional method to perform a P&A operation is to mill the casing and pull it to surface before ... -
Paleogeographic reconstruction of the northern Caribbean region from Late Cretaceous to the Recent
(Master thesis, 2014-06-16)The northern Caribbean region is geologically complex region and is located between two large hydrocarbon provinces (Gulf of Mexico and the South American continental margins). Using a mega-regional dataset that includes ... -
Paleozoic-Holocene tectonostratigraphic evolution of the Sørvestlandet High and the Åsta Graben, Southern Norwegian North Sea
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)This study is presenting a three-dimensional seismic data set and published data from exploration wells which were used to reconstruct the tectonostratigraphic evolution of the Sørvestlandet High, Southern North Sea, Norway. ... -
Paradigm Shift in International Gas Market Towards an Integrated Market? - Possible Impacts on Markets in East Asia and North West Europe
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-14)Currently gas markets are largely regional and segmented as the result of transport complexities, differences in regional price formation and regulatory factors. Natural gas is more difficult to transport than oil and ... -
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 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 ... -
