Raman spectroscopy applied to enhanced oil recovery research
(Master thesis, 2015-06-09)It is well established that aqueous chemistry affects the mechanical strength of chalk. Seawater tends to weaken chalk at reservoir temperatures and consequently the recovery rate. As more than 50 % of the oil in existing ... -
Rate of penetration optimization using moving horizon estimation
(Journal article; Peer reviewed, 2016)Increase of drilling safety and reduction of drilling operation costs, especially improvement of drilling efficiency, are two important considerations in the oil and gas industry. The rate of penetration (ROP, alternatively ... -
Real time production monitoring with prediction and validation
(Masteroppgave/UIS-TN-IPT/2009, Master thesis, 2009)This Master of Science studies Optimum Online’s real time estimated production at the Ekofisk Field. Information from offshore process sensors are used to validate the individual well estimates and to detect any deviation ... -
Recognition and quantification of petroleum source rocks from well log data and its applications
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2012-06)Petroleum source rocks constitute one of the main elements in petroleum systems. Several methods have been developed to characterize source rocks, mainly using geochemical and petrographical laboratory techniques to determine ... -
Reduction of the effective shear viscosity in polymer solutions due to crossflow migration in microchannels: Effective viscosity models based on DPD simulations
(Journal article, 2017-03)Molecular dynamics simulations (dissipative particle dynamics–DPD) were developed and used to quantify wall-normal migration of polymer chains in microchannel Poseuille flow. Crossflow migration due to viscous interaction ... -
Reelwell drilling method - installation and cementation of 10 ¾’’ casing and 7" liner - method and case example
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06)Current technology gives an opportunity to drill Extended Reach Drilling (ERD) wells with a tremendous length of horizontal departure. The Reelwell Drilling Method (RDM) is a drilling technology particularly suited for ... -
Reliability Based Casing Design
(Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)It is a well-known fact that wells are increasingly becoming extremely expensive and difficult to drill as well as develop due to increasing water depth, temperatures, and pressures. All these result in an increasing load ... -
Repeated post-Caledonian intra-cratonic rifting in the central North Sea: Evidence from the volcanic record in the Embla oil field
(Journal article; Peer reviewed, 2017-11)Intrusive and extrusive mafic igneous rocks in the Embla oil field, central North Sea, testify to repeated post-Caledonian magmatism on the northern flank of the Mid North Sea High. The igneous rocks are highly clay- and ... -
Reservoir characterization and conformance control from downhole temperature measurements
(Master thesis, 2015-07-15)Temperature plays an important role in reservoir development since it affects fluid and formation properties and it is especially important for EOR deployment. Downhole temperature measurements have been available for ... -
Reservoir characterization of Sognefjord and Fensfjord formations across Gjøa field, North Sea, Norway
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)The Gjøa field was discovered in 1989 and first production started in 2010 located about 40 kilometers north of the Fram field. The reservoir contains gas above a relatively thin oil zone in Jurassic sandstones in the ... -
Reservoir characterization of the Lower Cretaceous clastic wedges in the southwestern Barents Sea using seismic analysis and rock physics diagnostic
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-17)The southwestern Barents Sea is an underexplored area of the Norwegian continental shelf, with a few discoveries in Triassic and Jurassic reservoirs. Recently drilled exploration wells on the Loppa High and the surrounding ... -
Reservoir Characterization of the Skagerrak Formation
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)A petrophyscial evaluation has been generated for three wells penetrating the Skagerrak Formation in the Sleip ner Øst field, the Gungne field, and the Loke field in the Central North Sea, Figure 5 - 1. ... -
Reservoir characterization of the Snorre Field
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)The fluvial sandstone in the Snorre field consists of braided to meander streams deposited in arid and in humid climate that show a clear differences in the sedimentology and reservoir properties, especially the silt content ... -
