Patent number: 8499841Abstract: The present application is to a method of sequentially drilling a number of frac sleeves in a down hole well. The design enables the removal of fracture sleeve pistons from between treatment zones without requiring drilling or milling of the sleeve while allowing for full flow of fluids after treatment.
