Title

Evaluation of Adsorption of a Polymeric Surfactant on Reservoir Rock in Different Conditions and its Comparison with HPAM

Pages

  95-107

Abstract

 The loss of surfactants and Polymers in the injection process in reservoirs is considered the most crucial issue in the chemical injection process›s Feasibility. Simultaneous injection of Polymers and surfactants causes interaction between surfactant and Polymer and a significant reduction in performance. The best solution for solving this problem is using a new material called Polymeric Surfactant/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polymeric Surfactant that can be an exciting alternative for currently available methods. These new materials can have the effect of Polymer and surfactant like increase of water viscosity, reduction of interfacial tension between water and oil, and change in reservoir rock wettability simultaneously,thus, these new materials will further increase oil production relative to traditional methods. One of the fundamental problems of chemical injection is the Adsorption of these substances on the reservoir rock. Because of limited research regarding the analysis of the Adsorption rate of Polymeric Surfactant/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polymeric Surfactant on reservoir rocks and comparing them with the Adsorption rate of conventional Polymers, in this study, the Adsorption rate of this substance has been studied in different Temperatures. First, in this research, A HPAM and HMZPAM As a Polymeric Surfactant/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polymeric Surfactant synthesized using a Zwitterion hydrophobic group, and the effect of these two Polymers was measured in concentrations between 50 to 1000 mg/L at Temperatures between 25 to 80 oC on Adsorption of surface in carbonate rock. The results show that the Adsorption of HPAM and HMZPAM on reservoir rock, which made of Dolomite, increases with the increase in Polymer›s concentration. Generally, the main factor in the Adsorption of Polymers are electrostatic forces which because HMZPAM compared to HPAM, in addition to COO-group also has SO3-group that these negative groups adsorbed more to the positive charge of the rock surface in which as a result increases the amount of Adsorption of Polymeric Surfactant/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Polymeric Surfactant compared to HPAM.
