A mechanically-set packer system for use in a wellbore environment, the system comprising:
- a mandrel having an interior and an exterior;
- a packing element positioned along the exterior of the mandrel;
- a line positioned between the exterior of the mandrel and an interior of the packing element;
- and
- wherein the packing element includes a cut along an exterior of the packing element to enable the line to be installed from the exterior of the packing element to within the interior of the packing element.
(canceled)
A mechanically-set packer system for use in a wellbore environment, system comprising:
- a mandrel having an interior and an exterior;
- a packing element positioned on the exterior of the mandrel,
- wherein the mandrel and the packing element are configured to receive a line between the exterior of the mandrel and an interior of the packing element;
- and
- a cover positioned between at least a portion of the line and the interior of the packing element.
A mechanically-set packer system for use in a wellbore environment, the system comprising:
- a mandrel having an interior and an exterior;
- a packing element positioned along the exterior of the mandrel;
- and
- a sleeve formed of a non-swellable material and configured to provide complete circumferential coverage of at least a portion of a line, wherein the packing element is configured to receive the line and the protective sleeve therethrough, the protective sleeve forming a seal with the packing element.
(canceled)
A method for using a mechanically-set packer to isolate different portions of a wellbore while enabling communication therebetween, the method comprising:
- actuating a packing element to cause the packing element to extrude radially outwards and seal against a portion of a wellbore;
- providing a sleeve configured to provide complete circumferential coverage along a portion of a line positioned between an interior of the packing element and an exterior of a mandrel;
- sealing the packing element against the sleeve positioned between the interior of the packing element and the exterior of a mandrel;
- and
- communicating through the line.
