• The most widely used conventional fracturing stimulation, especially suitable for medium-deep wells, medium-temperature reservoirs (80~120℃), and most low-permeability reservoirs.
• Specific examples:
• Low permeability sandstone oil & gas reservoirs
• Wells with depth of 2000~4000 meters and formation temperature around 100℃
• Conventional tight gas, some shale gas (early stages or sections without high demands)
• The main fracturing fluid system for most oilfields (good overall performance, high cost-effectiveness)
