Abstract
A mechanically-set packer system for use in a wellbore environment may include a mandrel having an interior and an exterior. The system may further include a packing element positioned along the exterior of the mandrel. The system may also include a line positioned between the exterior of the mandrel and an interior of the packing element.
Claims23
A mechanically-set packer system for use in a wellbore environment, the system comprising:
- a mandrel having an interior and an exterior, the mandrel having a longitudinal recess in the exterior of the mandrel, the longitudinal recess configured to receive a line therein;
- a packing element having an exterior surface and an interior surface opposite of the exterior surface, the packing element positioned along the exterior of the mandrel;
- a line positioned between the exterior of the mandrel and the interior surface of the packing element;
- and
- wherein the packing element includes a single cut from the exterior surface of the packing element to the interior surface of the packing element to enable the line to be installed from the exterior surface of the packing element to within the interior surface of the packing element and wherein the line is installed through the cut to be positioned between the exterior of the mandrel and the interior surface of the packing element.
A mechanically-set packer system for use in a wellbore environment, system comprising:
- a mandrel having an interior and an exterior;
- a packing element having an exterior surface and an interior surface opposite of the exterior surface, the 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 the interior surface of the packing element;
- and
- a cover positioned between at least a portion of the line and the interior surface of the packing element, wherein a seal is created between the cover and the packing element when the packing element is expanded and set.
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 having an exterior surface and an interior surface opposite of the exterior surface, the packing element positioned along the exterior of the mandrel;
- and
- a protective 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 includes a cut along the exterior surface to receive the line and the protective sleeve therethrough, the protective sleeve forming a seal with the packing element, wherein the protective sleeve is positioned between the interior surface of the packing element and the exterior of the mandrel and wherein the protective sleeve increases the sealability between the line and the packing element.
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, the packing element having an exterior surface and an interior surface opposite of the exterior surface;
- providing a sleeve configured to provide complete circumferential coverage along a portion of a line positioned between the interior surface of the packing element and an exterior of a mandrel;
- sealing the packing element against the sleeve positioned between the interior surface of the packing element and the exterior of a mandrel;
- and
- communicating through the line.
