Evaluation of thin film composite membrane in production of ionically modified water applied for enhanced oil recovery
. The ion rejection values of the selected proper TFC membrane for sulfate, calcium, magnesium, sodium, and chloride were 90%, 43%, 67%, 6.5%, and 19%, respectively. Finally, the spontaneous imbibition test was performed to appraise the influence of smart...
Numerical Investigation of Contact Angle Effect on Counter-Current Spontaneous Imbibition
Medium wettability plays the main role during spontaneous imbibition (SI) in fractured porous media; however, one can rarely find pore-scale studies addressing wettability effects on this process. In present work Cahn–Hilliard phase field coupled...
Improvement of Water Displacement Efficiency in Sandstone Reservoirs Using Buffered Sodium Silicate
be explained by quartz surface charge modification due to alkalinity of sodium silicate as well as increased number of hydroxyl groups on the mineral surface due to silicate chemi-adsorption. Spontaneous imbibition tests at micro and macro-scale using glass...
Phase-Field Simulation of Counter-Current Spontaneous Imbibition in a Fractured Heterogeneous Porous Medium
Spontaneous imbibition is well-known to be of the most effective processes of oil recovery in fractured reservoirs. However, the detailed pore-scale mechanisms of counter-current imbibition process and the effects of different fluid/rock parameters...
A Discussion On Chemical/Physical Understanding of Ionically Modified Water EOR Method In Carbonate Reservoirs
Almost 90% of Iranian oil reservoirs are carbonate (limestone, dolomite or chalk). They are normally highly fractured, mixed to oil wet and have low matrix permeability. Since 1980’s, it has been discovered that water ...
Development of an assay to evaluate differences in germination rate among chickpea genotypes under limited water content
An assay system that provides rapid and reproducible germination under low soil water content (<10% water holding capacity (WHC)) was developed and used to compare how chickpea (Cicer arietinum L.) genotypes complete ...
