Link-up of mini-fractures from perforated holes
The link-up of mini-fractures from perforated holes on a deviated wellbore is analyzed in this chapter. The link-up of mini-fractures depends on the in situ stresses, fluid pressure, wellbore orientation, and the spacing between perforations.
Boundary integral method
Stress intensity factor
It has been demonstrated in the previous chapter that in order to minimize the turning and twisting of mini-fractures from the perforated holes and to facilitate the link-up of mini-fractures to form a large hydraulic fracture, the perforation has to be directed to the tension zone of the wellbore. Furthermore, ...
