Ascend™ Surfactant Solution Case Study Major Operator Optimizes Fracturing Fluid Efficiency with Customized Chemicals

Challenge

• Traditional surfactant fluid absorbed before it can travel the full length of the fracture

Solution

• Ascend™ surfactant to prevent absorption so surfactant can be more active, reach deeper into the formation, and drive increased oil recovery

Results

• Up to 150% uplift in daily initial production• Repayment of surfactant spend in less

than 2 weeks’ time• 2.7 times higher 90-day cumulative oil

production
