发明名称 DOWNHOLE PROGRESSIVE PRESSURIZATION ACTUATED TOOL AND METHOD OF USING THE SAME
摘要 A method of servicing a subterranean formation comprising positioning a wellbore servicing tool comprising an axial flowbore within a wellbore, making a first application of pressure to the axial flowbore of the wellbore servicing tool; wherein the pressure within the wellbore servicing tool is at least a first upper threshold during the first application of pressure, allowing the pressure within the axial flowbore following the first application of pressure to fall below a first lower threshold, making a second application of pressure to the axial flowbore of the wellbore servicing tool, wherein the pressure within the wellbore servicing tool is at least a second upper threshold during the second application of pressure, allowing a second subsiding of pressure within the axial flowbore following the second application of pressure to fall a second lower threshold, and communicating a fluid to the wellbore, the subterranean formation, or both via one or more ports of the wellbore servicing tool.
