Abstract
A packer that accommodates a control line or I-wire within its sealing element. The sealing element has a longitudinal groove to accommodate the I-wire or control line such that, when the sealing element is compressed, it closes around the I-wire or control line to envelope it as the sealing element makes peripheral contact with the casing, tubular, or the wellbore. The control line or I-wire does not go through the mandrel or body of the packer, and additional joints used in prior techniques for accommodating control lines or I-wires going around packers is eliminated.
Claims10
A packer for a wellbore or tubular, comprising:
- a body having a longitudinal axis;
- a sealing element on said body having an outer surface and having a top and bottom and movable between a retracted position for run-in and an expanded position for contact with the tubular or the wellbore;
- said sealing element comprising a passage extending from said top to said bottom to accommodate at least one elongated object which needs to extend beyond the sealing element in the wellbore;
- said sealing element sealingly surrounds the elongated object when in an expanded position;
- said passage comprising an open trough extending from an outer surface of the sealing element;
- and
- said outer surface when contacting the wellbore or tubular sealingly encloses said trough around the elongated object.
A wellbore or tubular packer comprising:
- a. a body having a longitudinal axis;
- b. a sealing element on said body having a outer surface and having a top and bottom and movable between a retracted position for run-in and an expanded position for contact with the tubular wellbore;
- c. said sealing element comprising a circle like passage located at the outer periephery of said sealing element, extending from said top to said bottom to accommodate at least one elongated object which needs to extend beyond the sealing element in the wellbore;
- and
- d. said sealing element is in segments;
- said passage defined between two of said segments.
A method of running at least one control line I-wire. or an elongated object past a packer, comprising:
- providing a longitudinal passage in a sealing element on the packer,
- extending the control line, I-wire, or elongated object through said passage;
- expanding the sealing element to close off a wellbore passage;
- and
- sealingly engaging and surrounding the control line, I-wire or elongated object with said sealing element as a result of said expanding:
- providing an external trough extending from an outer surface of said sealing element to act as said passage.
A method of running at least one control line one 1-wire, or an elongated object past a packer, comprising:
- providing a longitudinal passage accessible to an outer surface of a sealing element on the packer;
- extending the control line, I-wire, or elongated object through said passage;
- expanding the sealing element to close off a wellbore passage;
- and
- sealingly engaging the control line, I-wire or elongated object with said sealing element as a result of said expanding;
- providing a segmented sealing element such that said passage is defined by a circle like opening at said outer surface between adjacent segments.
