Experimental Investigation to Determine the Main Parameters for Viscoelastic Surfactant (VES) Injection for Acid Diversion in Reservoirs and Improving Their Design Conditions, M.Sc. Thesis Sharif University of Technology ; Ayatollahi, Shahab (Supervisor) ; Bazargan, Mohammad (Co-Advisor)
Abstract
The success of matrix acid production operations and its proper efficiency is one of the main challenges for oil and gas companies. The heterogeneity of the reservoir formation (especially the permeability difference) in the area around the well due to the presence of different reservoir layers results in the non-uniform distribution of acid among them and adds acidizing challenges. In order to improve production conditions, stimulation fluid transfer to the low permeability layer, which is the main target of acidizing. In this study, a new generation of chemical diverter, called Viscoelastic Surfactant, has been used. These materials have two components of elastic and viscous behavior, and...
