Enhanced Acid System
Polymer-based self-diverting acid that eliminates the possibility of fluid re-crosslinking during flow back. Offers extended crosslinking pH range. Offers high viscosities for more effective diversion, while fluid loses viscosities as pH raises. Uses internal breaker as secondary breaking mechanism.
The Baker Hughes Enhanced Acid System™ is a self-diverting acid system designed to increase efficiency when stimulating carbonate formations. The system has low viscosity when pumped, which minimizes surface horsepower requirements and permits high pump rates. As the acid spends in the formation, the system crosslinks and develops high viscosity, which increases acid diversion to increase the stimulated volume.
