A-Link (Cross-Linked Acid System)

A-link continues to gain viscosity as the acid spends. This occurs because the Cross-Linker is activated in a pH range of 1.5 to 4.5. As the pH becomes higher the system breaks and provides transport properties for insoluble material that may be present when well bore cleanup begins.

Advantages:  Reduces leak-off rates, provides deeper acid penetration before spending, creates longer fractures through diversion, enhances transport of insoluble material during cleanup, and can be formulated for applications up to 300⁰F
