Diverting acid for better stimulation

摘要

Optimized acid and diversion technology and long operations experience improve Saudi production and injection wells. Widely contrasting permeability and long horizontal intervals in Saudi Arabian wells complicate the design of matrix acidizing treatments to remove drilling-induced skin damage. Modern retarded acid systems and new diversion technologies have become typical components of effective stimulation treatments in these wells. Analyzing a large collection of operational case histories provides several design guidelines and best practices for matrix stimulation strategies in Saudi Arabia.
