摘要： The inventions provide apparatus and methods for radially expanding a tubular deployed in a subterranean well by moving an expansion tool axially through the well. An expansion tool apparatus may have wear faces attached to at least a portion of the outer periphery of a mandrel for contacting the interior surface of the pipe, tube, or screen during expansion. According to another aspect of the invention, an expansion tool has a controlled egress seal between the outer surface of the tool and the inside surface of the expandable tubular. According to another aspect of the invention, an automatically variable diameter expansion tool is provided having a variable diameter cone, which expands, and contracts based on input from one or more sensors. According to another aspect of the invention, an apparatus and method for expanding a length of screen assembly in a subterranean wellbore is provided.

摘要： A multi-zone packing system having unique features that allow for remote operation, thereby eliminating the need to raise and lower a work string and crossover tool to various zones of interest during a frac pack, gravel pack or related completion procedure. The squeeze pack system has a crossover tool or port collocated with each zone of interest and remotely operated closing devices to allow for the setting of each packer and the packing job to be performed with minimal or no movement of the work string.
