SPE 118830 Efficient Simulation for Low-Salinity Waterflooding in Porous and Fractured Reservoirs
Low-salinity brine injection has emerged as a promising, cost-effective improved oil recovery (IOR) method for waterflooding reservoirs. Laboratory tests and field applications show that low-salinity waterflooding could lead to significant reduction of residual oil saturation. There has been a growing interest with an increasing number of low-salinity waterflooding studies. However, there are f...
متن کاملTitle : “ Evaluation of the Impact of Reservoir Heterogeneity and Mixing on Low Salinity Waterflooding ” Speaker :
The impact of heterogeneity induced mixing between the injected low salinity water and the high salinity connate water is investigated in secondary low salinity waterflooding (LSW). Although LSW has proved to be a promising EOR process in laboratory experiments and field trials, its efficiency can be altered due to mixing with in situ higher salinity connate water. This mixing is caused by mole...
متن کاملSPE 113410 Application of Coalbed Methane Water to Oil Recovery by Low Salinity Waterflooding
Development and production of coalbed methane involves the production of large volumes of water. The salinities and sodium adsorption ratios of coalbed methane (CBM) water from the Powder River Basin range from 370 to 1,940 ppm and 5.6 to 69 respectively. Surface discharge of CBM water can create serious environmental problems; subsurface injection is generally viewed as economically nonviable....
متن کاملLow Salinity Oil Recovery - an Experimental Investigation
The idea of injecting low salinity water into a petroleum reservoir is not novel and was often used in the 70’s prior to the injection of surfactant. Yet, recently it was shown that simply injecting sufficiently low salinity water improves oil recovery (LoSalTM). Many possible mechanisms concerning Low salinity waterflood have been proposed in the literature. This paper describes an experimenta...
متن کاملEffects of Growth Stimulator Microbes on Growth and Ions Concentration of Stevia under Salinity Stress Conditions
Soil salinity and water deficit are major problems for development of agricultural production. In this study, effects of growth promoting microorganisms (inoculation with Piriformospora indica and two isolates of Streptomyces sp.) on the leaf yield and absorption rate of some elements in leaves and roots of stevia plant was investigated under salinity conditions for two consecutive years (2016-...
