Chemically induced compaction in fractured and intact chalk cores
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)The effect of pore water chemistry on the mechanical strength of chalk has been thoroughly investigated during the last years. Recent studies have demonstrated precipitation of new minerals that further triggers dissolution ... -
Mathematical modeling of water-rock chemistry during water injection and its impact on the composition and porosity of chalk
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010) -
The impact of temperature and non-carbonate minerals on chalk compaction
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)There has been a considerable research activity concerning the effect of brine chemistry on the mechanical behaviour of chalk since the discovery of the Ekofisk subsidence in the North Sea. Although the research on water ... -
Water induced compaction of chalks with varying non-carbonate content : the effect of Mg2+ and pH of the injected brines
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)The main objective for this study was to investigate the effect of alkaline brines on chalk, and the importance of non-carbonate content in chalk. This was done by flooding alkaline MgCl2 on Liège chalk – which has ... -
Water weakening of chalks - comparsion of intact and fractured cores
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Even though Chemical induced compaction on high porosity chalks has been studied extensively, little attention was given to the impacts of fractures when chalk is exposed to various flooding brines. Due to the nature of ...
