Use of a spindle to provide optical fiber in a wellbore

Abstract

A method of providing optical fiber in a wellbore may include lowering a spindle holding the optical fiber through the wellbore and anchoring a distal end of the optical fiber in the wellbore. The method may also include drawing the optical fiber from the spindle by pulling the spindle back through the wellbore. A device for providing optical fiber in a wellbore may include a spindle configured to hold at least a portion of the optical fiber as the spindle moves through the wellbore. The optical fiber is drawn from the spindle as the spindle passes through the wellbore.

1 . A method of providing optical fiber in a wellbore, comprising:
 lowering a spindle holding the optical fiber through the wellbore;   anchoring a distal end of the optical fiber in the wellbore; and   drawing the optical fiber from the spindle by pulling the spindle back through the wellbore.   
     
     
         2 . The method of claim  0 , wherein anchoring the distal end comprises:
 providing an anchor in the wellbore; and   attaching the distal end of the optical fiber to the anchor.   
     
     
         3 . The method of claim  0 , further comprising:
 providing the wellbore with a production tubing;   wherein the step of anchoring comprises providing an anchor downhole of a distal end of the production tubing; and   wherein the step of lowering the spindle comprises lowering the spindle through the production tubing.   
     
     
         4 . The method of claim  0 , wherein the step of providing the wellbore with the production tubing comprises lowering the production tubing into the wellbore. 
     
     
         5 . The method of claim  0 , wherein the step of providing the anchor occurs prior to the step of lowering the spindle. 
     
     
         6 . A method of providing optical fiber in a wellbore, comprising:
 anchoring a proximal end of the optical fiber proximate an entrance to the wellbore;   drawing the optical fiber from a spindle by lowering the spindle through the wellbore.   
     
     
         7 . The method of claim  0 , further comprising providing the wellbore with a production tubing, wherein lowering the spindle through the wellbore comprises lowering the spindle through the production tubing. 
     
     
         8 . The method of claim  0 , further comprising:
 providing an anchor downhole of a distal end of the production tubing; and   attaching a distal end of the optical fiber to the anchor.   
     
     
         9 . The method of claim  0 , wherein providing the anchor comprises:
 lowering the anchor before drawing the optical fiber from the spindle.   
     
     
         10 . The method of claim  0 , wherein the spindle is configured to act as an anchor, and wherein lowering the spindle comprises:
 lowering the spindle through the wellbore to a predetermined location within the wellbore.   
     
     
         11 . A method of providing optical fiber in a wellbore, comprising:
 lowering a spindle through the wellbore to a predetermined location within the wellbore; and   drawing the optical fiber from the spindle toward an entrance to the wellbore.   
     
     
         12 . The method of claim  0 , wherein the step of drawing the optical fiber from the spindle utilizes a float, the method further comprising:
 attaching a proximal end of the optical fiber to the float; and   allowing the float to move upward toward the entrance to the wellbore.   
     
     
         13 . The method of claim  0 , further comprising anchoring the proximal end of the optical fiber proximate the entrance to the wellbore. 
     
     
         14 . The method of claim  0 , further comprising:
 affixing the optical fiber to an interior of wellbore.   
     
     
         15 .- 21 . (canceled) 
     
     
         22 . A method of providing optical fiber in a wellbore, comprising:
 anchoring a spindle holding the optical fiber at surface; and
 drawing the optical fiber from the spindle by dropping the fiber into the wellbore. 
   
     
     
         23 . The method of  claim 22  comprising:
 providing the distal end of the optical fiber with a weight, to draw the distal end of the fiber into the wellbore assisted by gravity. 
 
     
     
         24 . The method of  claim 22 , comprising the step of:
 drawing the optical fiber into the wellbore until the distal end of the fiber has reached a predetermined location in the wellbore.   
     
     
         25 . The method of  claim 22 , comprising the step of:
 taking data using the optical fiber arranged in the wellbore; and
 using the spindle to pull the optical fiber back out of the wellbore. 
   
     
     
         26 . The method of claim  0 , further comprising:
 affixing the optical fiber to an interior of wellbore.   
     
     
         27 . The method of claim  0 , further comprising:
 affixing the optical fiber to an interior of wellbore.
