Method for gravel or frac packing in a wellbore and for monitoring the packing process

Abstract

A method for gravel packing or frac packing in a borehole includes running a workstring to a target location, running an optic fiber to the location with the workstring and monitoring the target location with the optic fiber. A method for monitoring at least one parameter at a plurality of discrete locations at a gravel packing or frac packing location in a borehole including running a workstring to the gravel packing or frac packing location running an optic fiber to the gravel packing or frac packing location along with the workstring and monitoring the gravel packing or frac packing location at a plurality of discrete points along the gravel packing or frac packing location.

1 . A method for gravel packing or frac packing in a borehole comprising: 
 running a workstring to a target location;    running an optic fiber to the location with the workstring; and    monitoring the target location with the optic fiber.    
   
   
       2 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  further including: 
 packing the target location.    
   
   
       3 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the monitoring includes querying the target location at a plurality of discrete selective points therealong.  
   
   
       4 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the method further includes mapping the target location using selective monitoring of a plurality of points therealong.  
   
   
       5 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the method further includes removing the optic fiber from the borehole.  
   
   
       6 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the removing of the optic fiber occurs with the removal of the workstring.  
   
   
       7 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the optic fiber is run inside a control line.  
   
   
       8 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the monitoring includes measuring pressure at plurality of discrete selected points within the target location.  
   
   
       9 . A method for gravel packing or frac packing in a borehole as claimed in  claim 1  wherein the monitoring includes measuring temperature at plurality of discrete selected points within the target location.  
   
   
       10 . A method for monitoring at least one parameter at a plurality of discrete locations at a gravel packing or frac packing location in a borehole comprising: 
 running a workstring to the gravel packing or frac packing location;    running an optic fiber to the gravel packing or frac packing location along with the workstring; and    monitoring the gravel packing or frac packing location at a plurality of discrete points along the gravel packing or frac packing location.    
   
   
       11 . A method for monitoring at least one parameter at a plurality of discrete locations at a gravel packing or frac packing location in a borehole comprising: 
 disposing an optic fiber at a workstring in the downhole environment while the workstring is in the downhole environment;    measuring at least one parameter of the downhole environment at a plurality of discrete locations; and    removing the optic fiber from the downhole environment while the workstring is removed from the downhole environment.    
   
   
       12 . A method for monitoring at least one parameter at a plurality of discrete locations at a gravel packing or frac packing location in a borehole as claimed in  claim 11  wherein the optic fiber is disposed within a control line.  
   
   
       13 . A workstring comprising provision for association therewith of an optic fiber such workstring and optic fiber being runnable into and out of a borehole over short duration.
