HYDRAULIC FRACTURING USING PETROLEUM COKE |
摘要 |
A fluid containing suspended particles of petroleum coke is injected into a fracture formed in a subterranean formation. The injection conditions are such that the coke particles are carried to the ends of the fracture where they screen out and form low permeability zones. Continued injection of a fluid produces an increase in fracture pressure increasing the dynamic width of the fracture.
