... developed. This accounts for fracture geometry and for acid fracturing job specifications. Acid fracturing is typically conducted in carbonate reservoirs, which make up approximately 70% of the worldwide hydrocarbon reserves. Acid fracturing is a complex process depending on multiple factors which...
