Permanent packer using a slurry inflation medium

Abstract

A system for forming a seal in a wellbore includes a slurry source, an expandable inflatable element, and a filter. The slurry may contain particles entrained in a fluid carrier. The filter may be configured to separate the particles from the fluid carrier to form a relatively solid body in the inflatable element. The system may include a pump configured to pressurize the slurry. The pump may flow the slurry from a surface location or from a location in the wellbore. The source may be a bailer configured to receive a pressurized fluid from the pump. The system may use a hydraulic disconnect that conveys the slurry from the source to the inflatable element. The hydraulic disconnect may be configured to disconnect the source from the inflatable element upon a predetermined pressure being reached in the inflatable element. The particles may be formed of a compressible material.
