smart Water as wettability modifier in carbonate and sandstone a discussion of similarities differences in the chemical mechanisms
Energy & Fuels, 2009Co-Authors: Alireza Rezaeidoust, Tina Puntervold, Skule Strand, Tor AustadAbstract:Waterflooding has for a long time been regarded as a secondary oil recovery method. In the recent years, extensive research on crude oil, brine, and rock systems has documented that the composition of the Injected Water can change wetting properties of the reservoir during a Waterflood in a favorable way to improve oil recovery. Thus, injection of “smart Water” with a correct composition and salinity can act as a tertiary recovery method. Economically, it is, however, important to perform a Waterflood at an optimum condition in a secondary process. Examples of smart Water injection in carbonates and sandstones are: (1) injection of seaWater into high temperature chalk reservoirs and (2) low salinity floods in sandstone reservoirs. The chemical mechanism behind the wettability alteration promoted by the Injected Water has been a topic for discussion both in carbonates and especially in sandstones. In this paper, the suggested mechanisms for the wettability modification in the two types of reservoir rocks a...

a new model for discriminating the source of produced Water from cyclic steam stimulation wells in edge bottom Water reservoirs
Energies, 2020Co-Authors: Shi Jun Huang, Menglu Yang, Lun Zhao, Tong WuAbstract:Heavy oil reservoirs with edge-bottom Water represent a huge portion of the world’s reserves, and the effective development of such reservoirs with cyclic steam stimulation (CSS) is significant for the petroleum supply. However, the Water cut of some CSS wells increases, and production decreases, with the increase of circulation turns. Discerning the source of the produced Water is the basis of targeted treatment measures. In this paper, a new model is established for discriminating the source of produced Water from CSS wells in edge-bottom Water reservoirs. The model combines traditional hydrochemical characteristics analysis and factor analysis, and considers the quality change in Injected Water. The coefficient of formation Water and Injected Water in produced Water can thus be obtained. In addition, the normal distribution method is used to further divide interlayer Water and edge-bottom Water. The model was applied to a field case, and the results showed that one well was severely invaded by edge-bottom Water. The results are consistent with field production performance, which further verifies the accuracy of the model. This model is of great significance for not only discriminating the source of produced Water in an edge-bottom Water reservoir, but also providing a basis for further the provision of further treatment measures.
