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 Mixing and Separation Mechanisms of Oil-Water System
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)The behaviour of oil-water mixtures/emulsions is of great importance for a variety of industries and sciences. Specially in oil and gas industry, it can be encountered at different stages while drilling, production, storage, ... -
Experimental investigation of polymer flow through water- and oil-wet porous media
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The majority of the research conducted on polymer behavior in porous media is either for single phase flow or water-wet cores. The effect of wettability on polymer behavior in porous media is the main focus of this work. ... -
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 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 ... -
