Horizontal wells with long propped fractures are needed to maximize productivity for ultra-low permeability shale and tight reservoirs. Conventional slickwater fracturing with sand can produce long fractures, but only the near wellbore region is propped due to fast settling of sand in water. Ultra-light weight proppants (ULWPs) can be used to reduce proppant settling. A comprehensive investigation...
Multi-stage hydraulic fracturing is the method for unlocking shale gas resources and maximizing horizontal well performance. Modeling the effects of stimulation and fluid flow in a medium with extremely low permeability is significantly different from modeling conventional deposits. Due to the complexity of the subject, a significant number of parameters can affect the production performance. For...
