文摘
- •
Higher order DDM with four special crack tip elements is used for more accuracy.
- •
Hydraulic fracturing as applied to well stimulation is analyzed.
- •
Interaction of several pre-existing fractures starting from a wellbore is studied.
- •
Propagation, arrest and interference of pre-existing fractures have been observed.
- •
Critical inclination angles are suggested for better results in hydraulic fracturing.
