A comprehensive experimental study for optimization of fracture stabilizers

• Comprehensive evaluation of long term sand control and conductivity maintain.
• Compatibility with commonly used fracturing fluid of fracture stabilizer was evaluated.
• Dosage of fracture stabilizer was optimized.

A Gum fracturing fluid compatible fracture stabilizers was selected through experimental evaluation in the former research. The simulation experiments show that the flow conductivity of fractures could be maintained by fracture stabilizer, and the number of intrusive particles in the proppant processed by stabilizers was significantly reduced. The dosage of the fracture stabilizer was optimized according to comprehensive experiments of long term conductivity and sand control effect under condition of bilinear flow. Results showing that conductivity decreases over time and reaches steady state after 5 days. The conductivity reduction decreases with the increase of stabilizer mass fraction. After a comprehensive evaluation, fracture stabilizer of 3–5% mass fraction is recommended.
