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 ... -
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 ... -
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 ... -
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 ... -
Reservoir characterization through numerical models
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Numerical models have been generated for two DST’s run in the Ile and Tilje formations in the exploration wells 6406/2-2 and 6406/2-4SR in the Lavrans field located in the mid-Norwegian sea at Haltenbanken. DST 2 in well ... -
Reservoir potential in the Klappmyss Formation, Barents Sea
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06)By May 2012 there are a total of 91 exploration and appraisal wells in the Norwegian sector of the Barents Sea, and more than 300 000 km of seismic reflection data. Moreover, estimation from Norwegian Petroleum Directorate ... -
Reservoir wetting in sandstone reservoirs, adsorption of polar basic oil components onto quartz and feldspar minerals.
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)For more than a decade the mechanism behind flooding with low salinity water have been studied and well documented as increased oil recovery method (EOR) in sandstone reservoirs. Recently Austad et. al. proposed a new ... -
Retention of polar oil components in low salinity water flooding
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-14)The influence of brine chemistry, salinity and composition on the retention of polar oil components onto reservoir rock mineral surface in relation to low salinity water flooding (LSWF) was studied and evaluated in this ... -
Review of completion technologies
(Master thesis, 2015-06)It used to be that completion expenditures were a modest proportion of the total capital costs and field development time. Today the wells have become exponentially challenging along with new field development discoveries. ... -
