Oilfield Chemicals UBEOR-331 Self-diverting Agent for Acid Fluid

UBEOR-331 represents a significant advancement in well stimulation technology, specifically engineered to enhance the efficiency and effectiveness of acidizing operations. This modified polyacrylamide-based self-diverting agent delivers exceptional performance in controlling acid placement and improving reservoir contact during stimulation treatments. The innovative formulation addresses critical challenges in matrix acidizing and fracture acidizing applications through its unique combination of properties.

The product demonstrates remarkable capabilities in gelling acid systems, effectively delaying acid-rock reaction rates while significantly reducing fluid leak-off into high-permeability zones. This controlled reaction mechanism enables more uniform acid distribution throughout the reservoir, maximizing contact with less permeable formations and improving overall stimulation effectiveness. The rapid dissolution characteristics ensure quick integration into acidizing fluids, immediately enhancing viscosity and developing optimal diverting properties.

UBEOR-331 maintains stable performance under high-temperature conditions, making it suitable for challenging reservoir environments where thermal stability is crucial. The outstanding low friction performance contributes to reduced pumping pressures and improved hydraulic efficiency during injection operations. The excellent compatibility with various acid systems and reservoir fluids ensures reliable performance across diverse operational scenarios.

For standard diverting applications, recommended concentrations range from 0.3% to 1.0%, tailored to specific formation characteristics and treatment objectives. The product's efficient mixing properties facilitate preparation using Venturi principle systems, where powder is injected through an ejector and thoroughly blended with acid fluid. This method ensures homogeneous solution preparation with two to three circulation cycles, typically followed by overnight maturation before application.

As an effective drag reduction agent, UBEOR-331 demonstrates exceptional performance at concentrations of 0.1-0.15%, achieving friction reduction rates exceeding 70% at flow velocities above 8 m/s. This dual functionality provides additional value in operations requiring both effective diversion and improved flow characteristics.

The advanced technology behind UBEOR-331 supports enhanced reservoir productivity through improved acid placement and controlled reaction kinetics. The product's balanced performance characteristics make it particularly valuable for carbonate formations and heterogeneous reservoirs where uniform acid distribution is challenging to achieve.
