Abstract
An apparatus for storing cable along a tubular in a wellbore using a first retainer for attachment to the tubular at a first location and a second retainer for attachment to the tubular at a second location. Each retainer is constructed and arranged to reverse the direction of the cable and to at least partially retain the cable due to elastic forces therein. In one embodiment, the cable is formed into a plurality of loops, each having an upper end retained by the first retainer and a lower end retained by the second retainer.
Claims20
An apparatus for storing cable along a tubular in a wellbore, comprising:
- a first retainer for attachment to the tubular at a first location;
- a first plurality of main formations and side formations disposed on the first retainer;
- a second retainer for attachment to the tubular at a second location;
- each retainer constructed and arranged to reverse the direction of the cable and to at least partially retain the cable due to elastic forces therein;
- and
- a second plurality of main formations and side formations disposed on the second retainer;
- wherein the first and second retainers are each locatable at a different predetermined axial location along a wall of the tubular;
- wherein the retainers are installed in a manner whereby each main formation of the plurality of main formations on the first retainer are rotationally distinct from each main formation of the plurality of main formations on the second retainer.
A method of storing cable along a tubular in a wellbore, comprising:
- securing first and second retainer around an outer wall of the tubular, each retainer having a plurality of main formations disposed thereon;
- anchoring the cable at a first location on a main formation on one of the first and second retainers;
- extending a predetermined length of the cable along the outer wall in a direction substantially parallel to the axis of the tubular;
- anchoring the cable at a second location on a main formation on the other of the first and second retainers;
- extending a second predetermined length in the direction of the first anchor location;
- whereby at each anchor location the cable is at least partially retained by elastic forces in the cable.
An apparatus for storing cable along a tubular in a wellbore, the apparatus comprising:
- a first retainer disposed on the tubular at a first location and having a first plurality of main formations and side formations;
- and
- a second retainer disposed on the tubular at a second location and having a second plurality of main formations and side formations;
- wherein the first plurality of main formations on the first retainer are circumferentially staggered from the second plurality of main formations on the second retainer.
