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 ... -
Advancement of P&A operations by utilizing new PWT concept from Archer
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)Many of the oil and gas fields on the Norwegian continental shelf (NCS) are approaching the end of field life. The Petroleum safety authority of Norway is putting pressure on the Exploration and Production (E&P) companies ... -
Alternative cement program for the surface casing in the skarv field
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)A phenomenon called Shallow Water Flow (SWF) was encountered when drilling the top sections at the Skarv field, causing difficulties when cementing the surface casing. This thesis describes a proposed cement program with ... -
Alternative production scenarios of the Gyda field
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)The Gyda field has been on stream since June 1990. Water injection commenced Feb. 1991. Currently Gyda is suffering from high water cuts. Having in mind that water injection is very costly, environmentally pollutant and ... -
