Abstract: The effervescent tablet for enhanced oil recovery is made of multi-walled carbon nanotubes (MWCNTs), sodium dodecyl sulfate (SDS), sodium phosphate monobasic (NaH2PO4), and sodium carbonate (Na2CO3). To perform enhanced oil recovery, a suspension is first prepared by adding the effervescent tablet to water. This preparation may be performed at room temperature. Steam is then injected into the oil well, followed by flooding the oil well with the suspension. One-third of the pore volume of an oil reservoir of the oil well may be injected with the steam, and two-thirds of the pore volume of the oil reservoir may be flooded with the suspension.
