New technology trends for effective plug and abandonment
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-08)Plug and Abandonment (P&A) has become a major focus in the petroleum industry and especially in Norway due to the maturity of the fields. Therefore, an extensive number of wells to be abandoned just show how big the challenge ... -
Numerical Simulation and Experimental Study of Reelwell’s Heavy over Light Solution in Vertical Well Sections
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Reelwell has developed the Reelwell Drilling Method (RDM), including the Heavy Over Light (HOL) solution. The HOL solution allows drilling with simultaneously use of two different drilling fluids, i.e. a near static ... -
Numerical simulation of chemical flow-zone isolation
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Silicate gel has been mostly used for near well treatment. A field test in the Snorre reservoir on the Norwegian Continental Shelf (NCS) has been planned, where the object of the test is to technically qualify silicate gel ... -
Numerical simulation of co-current and counter-current imbibition
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)Spontaneous imbibition (SI) is a very important mechanism for oil recovery in naturally fractured reservoirs. Several studies have indicated that counter-current oil production is much slower and give lower ultimate oil ... -
Numerical simulation of productivity effects by hydraulic fracturing in a low permeability fluvial reservoir in the north sea
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)A simulation study was performed on a recently discovered oil field. The operator is Talisman Energy, and the reservoir is complex in terms of disconnected fluvial channels, surrounded by a large majority of shale. The ... -
Numerical simulation of Spontaneous Imbibition of Smart Water into Preferentially oil-wet Carbonate using ECLIPSE 100
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Spontaneous imbibition (SI) is the main recovery mechanism in low matrix perme- ability, naturally fractured reservoirs. However, for imbibition to occur, the reservoir rock should be preferentially water-wet. Several ... -
Numerical simulation of surfactant flooding in mixed wet reservoirs
(Masteroppgave/UIS-TN-IPT/2010;, Master thesis, 2010)Surfactants have been considered for enhanced oil recovery either by reduction of oil–water interfacial tension (IFT) or through wettability alteration. This study reveals the effect that reduced interfacial tension has ... -
Offshore Exploratory Drilling Campaigns During Low Oil Price Period: Maximizing Value Creation from Flexibility
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06-15)During severe oil price downturns, many operating companies reduce or eliminate large investments with long time horizons such as exploratory drilling campaigns. This reduction in investments forces rig and drilling services ... -
