Post installation cured braided continuous composite tubular
First Claim
1. A method of providing a barrier at a predetermined location in downhole operations, the method comprising:
- a) providing a first tubular sleeve of a woven material comprising a plurality of fibers in a braided arrangement, said tubular sleeve including a conductor selected from the group consisting of electrical conductors and optical fibers;
b) impregnating the sleeve with a curable resin;
c) radially enlarging the sleeve at the predetermined downhole location; and
d) curing the resin.

Abstract
A method for providing a barrier at a predetermined location in downhole operations comprises: providing a first tubular sleeve of a woven material comprising a plurality of fibers in a braided arrangement and including a conductor, impregnating the sleeve with a curable resin, radially enlarging the sleeve at the predetermined downhole location, and curing the resin. The present method can also be used to provide a barrier at a desired location within a wellbore while drilling, to restrict sand flow into a wellbore while allowing fluid flow into the wellbore, or to protect a metallic sand screen by employing the composite braided tubular sleeve as a protective shroud.

10. A method of installing a tubular member in a wellbore, the method comprising:
-
a) providing an expandable tubular member;
b) providing a flexible tubular sleeve around the tubular member, the sleeve comprising a plurality of fibers woven in a braided arrangement and a curable component;
c) installing the expandable tubular member in the wellbore;
d) expanding the expandable tubular member and flexible tubular sleeve in the wellbore; and
e) curing the curable component of the tubular sleeve so as to form a rigid sleeve. - View Dependent Claims (11, 12, 13, 14, 15)

21. A method for restricting sand flow into a wellbore while allowing fluid flow into the wellbore, comprising
providing a braided tubular sleeve; -
positioning the sleeve at a desired location where it is desired to restrict sand flow;
impregnating the sleeve with a curable composition;
expanding the sleeve such that it contacts the borehole wall; and
curing the curable composition so as to set the sleeve such that liquids can pass through the set sleeve but particulates cannot. - View Dependent Claims (22)
