A Study of Scale and Scaling Potential during High Salinity and Low Salinity Waterflooding
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)Formation damage has been observed to be one of the severe problems during field life operation. In the waterflood projects, proper design water injection at the beginning of field life is crucial to minimize effects of ... -
Adsorption of quinoline onto illite at high temperature in relation to low salinity water flooding in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Laboratory tests, as well as field tests, have shown that low salinity water flooding in sandstone reservoirs can improve the water wetness of the rock and thereby increase the oil recovery. Many mechanisms have been ... -
An experimental study of low salinity EOR effects on a core from the Yme field
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The best known proposed mechanisms for low salinity effect are fines migration, pH increase, double layer expansion and multicomponent ionic exchange (MIE). Even though many mechanisms have been proposed, none of them have ... -
Effect of Various Silica Nanofluids: Reduction of Fines Migrations and Surface Modification of Berea Sandstone
(Journal article; Peer reviewed, 2017-11)Abstract: This work is aimed at addressing surface modification of berea sandstone by silica nanofluids (NFs). Three types of nanofluids were used: silica/deionized water (DIW), silica in DIW with a stabilizer fluid ... -
Evaluation of using Smart Water to enhance oil recovery from Norwegian Continental Shelf sandstone reservoirs.
(Master thesis, 2016-06-09)Recently, the scale of studies on smart water – one of EOR method - has increased. From decades, water flooding is one of the most used methods to increase oil recovery. However, more effective in sandstone reservoirs is ... -
Geochemical modeling of low salinity core flooding
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Extensive research the last decades has shown that lowering the salinity and ionic compostion of injection water can improve thre oil recovery. The mechanisms causing low salinity water to give favorable reservoir conditions ... -
LWSF simulation at larger scale
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)Low salinity water flooding is a field of science that is new and need more research to find a definite theory of what happens. There have not been done many modeling studies on this field. The objective of my thesis ... -
Modelling of water-oil flow in reservoirs including effects from gravity, capillary pressure and water rock chemistry
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-07-01)In this work we use mass balance equations to arrive at a classical description of the Buckley-Leverett equation for two phase flow in a one dimensional porous medium. Through the use of explicit numerical techniques we ... -
Smart water EOR effects in preserved sandstone reservoir cores, comparison between sea water and low salinity brines at 136°C
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Low salinity waterflooding is an emerging EOR technique that injects water at significant lower ions concentration as compared to the formation water. Laboratory experiments and field tests show that it can enhance the oil ... -
Smart water EOR in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)This study attempts to assess the viability of injecting medium-salinity brines of 25.000 ppm NaCl as a substitute for 1.000 ppm low-salinity Smart Water for injection in sandstone reservoirs, as well as study the effect ... -
Temperature effects in low salinity waterflooding
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)In the past years it has been observed that low salinity floods often lead to production of additional oil recovery. Several theories have been proposed as explanation for improved oil recovery, though the key mechanism ...
