Experimental Design and Setup of Circulation Flow Loop - Using Particle Image Velocimetry
(Master thesis, 2017-07-25)Mud left static in a well over a longer period of time can begin to gel up or form filter cakes along the formation wall and in washout zones, which can be difficult to remove. Therefore, proper mud mobilization and removal ... -
Experimental investigation at heavy light interface mixture of Reelwell ERD
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)Due to longer offset and large surface area exposure in a reservoir, extended reach drilling (ERD) is a method which is both cost effective and a well potential during the production phase. However, the present ERD method ... -

Experimental investigation of the potential of UCA and NMR for the detection of particle sedimentation in drilling fluids
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Both ultrasound and Nuclear Magnetic Resonance (NMR) have previously been investigated for the potential of monitoring barite sag in drilling fluids. The Ultrasonic Cement Analyzer (UCA) registers the speed of ultrasound ... -
Experimental lost circulation and performance simulation studies of 60/40, 70/30, 80/20 and 90/10 OBMs
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Lost circulation has been and still is a cost factor for the drilling industry. By using lost circulation material in drilling fluid, it is possible to mitigate unnecessary loss of drilling fluid. This thesis presents ... -
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 ... -
Experimental Study on Automatic Evaluation of Drilling Fluid Properties
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-14)The drilling fluid has several important functions such as transporting cuttings out of the well and being a primary barrier during the drilling operation. When drilling challenging wells in the present and future, factors ... -
Experimental study on cuttings transportation in turbulent pipe flow
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Experimental investigation on cuttings transportation in turbulent flow, in both horizontal and inclined pipes were performed in the multiphase-laboratory at the University of Stavanger. Spherical glass particles were used ... -

Extended Reach Drilling on the example of Reelwell Drilling Method: Influence examination of different drill pipes on drilling performance on Idun field on the Norwegian Continental Shelf by PGNiG Norway AS.
(Master thesis, 2011)Horizontal or extended reach drilling is incredibly fast growing technology. Although in some areas of the world ERD is still novelty, most of oil companies have been using the technology reliably and successfully for ... -
Extended reach drilling using RDM - heavy over light solution. Stability and control of the well annulus fluid
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)The oil and gas industry has large benefit from cost reductions and increased efficiency. One of the segments that is most affected by these factors is the drilling industry. There are large costs related to rig rates, ... -
Extending a drift-flux model for more realistic prediction of transient flow in UBO
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The transient behavior of the bottomhole pressure during underbalanced drilling operations has been investigated. Focus has been on jointed pipe drilling with gas injection through the drill string. A description is made ... -
Facies Modelling Based on Multi-Point Statistics (MPS) in Submarine Fan Deposits
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016)Multi-point statistics (MPS) is a relative new geostatistical facies modelling technique that was welcomed by oil industry as a promising alternative to the classical methods (object-based and pixel-based modelling). However ... -
