application
hydra-jet fracturing is a new stimulation method which incorporates hydra-jet perforation, hydraulic fracturing and hydraulic isolation. high pressure fluid which contains abrasive material is pumped through the nozzles of hydra-jet fracturing tool and high speed jet flow is formed to perforate the casing and cement sheath. pore path is created in near wellbore formation to establish communication between formation and casing. high pressure fluid is pumped into annulus to superimpose the nozzle jet flow pressure and fracture the formation. fracturing operation is then started.
features
1. high pressure hydraulic jetting and fracturing are combined. perforation is not necessary. no compacted zone.
2. high pressure jet flow creates unique hydraulic isolation. running a packer is not necessary.
3. suitable for all well types, such as vertical and horizontal wells.
4. suitable for several completion methods, such as casing completion, openhole completion and screen pipe completion.
