(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Flømming med vann med lav saltkonsentrasjon har blitt en vel dokumentert økt oljegjenvinningsmetode (EOR) i sandsteins reservoarer. Både eksperimentelt og i felten. -
Smart water EOR effects in preserved sandstone reservoir cores, comparison between sea water and low salinity brines at 136°C
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Low salinity waterflooding is an emerging EOR technique that injects water at significant lower ions concentration as compared to the formation water. Laboratory experiments and field tests show that it can enhance the oil ... -
Smart water EOR in sandstone reservoirs
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-13)This study attempts to assess the viability of injecting medium-salinity brines of 25.000 ppm NaCl as a substitute for 1.000 ppm low-salinity Smart Water for injection in sandstone reservoirs, as well as study the effect ... -
“Smart water” as a wettability modifier in chalk: The effect of salinity and ionic composition
(Doctoral thesis; Journal article; Peer reviewed, 2010)Seawater can improve the water wetness of chalk at high temperatures, which improves the oil displacement by spontaneous imbibition of water. It is experimentally verified that the interaction between Ca2+, Mg2+, and SO42− ... -
Strength development of aplite-based geopolymer cements
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-05-21)The purpose of this work is to investigate and develop aplite-based geopolymer as an alternative material for Portland cement. This was done by conducting a series of experiments using an Ultrasonic Cement Analysis (UCA) ... -
Structural analysis of the Tabaco anticline, Cerrejon mine, Northern Colombia (South America)
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-13)The Tabaco anticline is located in the Cesar-Ranchería basin of northern Colombia, South America, close to the transpressional collision between the Caribbean and South American plates. The anticline is bounded by the ... -
Structural uncertainty in assisted history matching
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-16)Uncertainty in the building of a 3D geo-model process is a result of our limited knowledge of the actual condition (Bratvold, R. B. and Begg, S. H., 2010). Many interpretations, analogues, estimations and simplifications ... -
Study of a model for spontaneous imbibition as a mechanism for oil recovery in naturally fractured reservoirs
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-06-10)One of the principal recovery mechanisms in Naturally Fractured Reservoirs (NFRs) is spontaneous imbibition. Understanding the parameters affecting spontaneous imbibition is the first step to achieve optimum oil recovery ... -
Study of CO2 properties and transportation for injection well into reservoir
(Masteroppgave/UIS-TN-IPT/2007, Master thesis, 2007)One of the possible solutions to reduce CO2 emission in atmosphere is to inject for storage in reservoir. This action is known as the residual gas geological storage project. One of the important aspects in this project ... -
