• Applicable scenarios:
• Low permeability, tight gas/oil reservoirs: Especially suitable for ultra-low permeability reservoirs sensitive to damage.
• Water-sensitive formations: Formulations can be designed to cause no clay damage.
• Shale gas (main fracture + complex fractures): Balances proppant transport and low damage.
• Offshore/environmentally sensitive areas: Low biotoxicity, lower environmental pressure.
• Refracturing/old well stimulation: Avoids secondary damage.
• Typical limitation: High cost, may break prematurely upon contact with crude oil or formation water.
