US Patent:

20170159375, Jun 8, 2017

Filed:

Aug 4, 2014

Appl. No.:

15/323656

Inventors:

- Houston TX, US
Wei Zhang - Plano TX, US
David L. Perkins - The Woodlands TX, US

International Classification:

E21B 17/20
D07B 1/16
D07B 1/14
E21B 19/08
E21B 47/00

Abstract:

In accordance with embodiments of the present disclosure, a slickline for use in well drilling and hydrocarbon recovery operations includes a cable and an intermediate layer disposed around the cable. The slickline also includes a doped polymeric coating layered around the intermediate layer. The doped polymeric coating is a different material from the intermediate layer, and the doped polymeric coating includes a polymeric material doped with an element that is detectable within the doped polymeric coating via a detection machine for purposes of determining wear or other aspects about the conditions of the slickline.

International Classification:

E21B 47/00
G02B 6/50
E21B 17/00
G02B 6/44

Abstract:

Downhole slickline cable including a polymer matrix having reinforcing fibers embedded therein. A plurality of integrity-sensing optical fibers are embedded within the polymer composite and extend along an axial length of the downhole slickline cable that enables slickline cable structural and mechanical integrity self-diagnosis. The cable may include energy transmission lines that include one or more integrity-sensing optical fibers.
