Abstract

A method for preparing a borehole for fracturing including inserting an assembly comprising a fracture plug, a setting tool, a perforating gun and a controller into a borehole, delivering the assembly to a target location, automatically recognizing the target location, automatically setting the plug of the assembly at the target location, and automatically initiating the gun of the assembly to perforate the borehole.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for preparing a borehole for fracturing comprising:
 inserting an assembly comprising a fracture plug, a setting tool, a perforating gun and a controller into a borehole;   delivering the assembly to a target location;   automatically recognizing the target location;   automatically setting the plug of the assembly at the target location; and   automatically initiating the gun of the assembly to perforate the borehole.   
     
     
         2 . The method as claimed in  claim 1  wherein the delivering is dropping. 
     
     
         3 . The method as claimed in  claim 1  wherein the delivering includes pumping. 
     
     
         4 . The method as claimed in  claim 1  wherein the recognizing is by sensing one or more of a physical feature, an electromagnetic feature, a radiologic feature or a chemical feature. 
     
     
         5 . The method as claimed in  claim 4  wherein the physical feature is a casing collar, a recess or a profile. 
     
     
         6 . The method as claimed in  claim 4  wherein the electromagnetic feature is a field. 
     
     
         7 . The method as claimed in  claim 4  wherein the electromagnetic feature is a Radio Frequency Identification (RFID) tag. 
     
     
         8 . The method as claimed in  claim 4  wherein the radiologic feature is a seismic signal or a gamma ray signature. 
     
     
         9 . The method as claimed in  claim 4  wherein the chemical feature is a chemical signature. 
     
     
         10 . A method for fracturing a borehole comprising:
 inserting an assembly comprising a fracture plug, a setting tool, a perforating gun and a controller into a borehole;   delivering the assembly to a target location;   automatically recognizing the target location;   automatically setting the plug of the assembly at the target location;   automatically initiating the gun of the assembly to perforate the borehole; and   pressuring on the borehole to fracture a formation surrounding the borehole.   
     
     
         11 . The method as claimed in  claim 10  further comprising milling the assembly out of the borehole. 
     
     
         12 . A fracturing assembly for a borehole comprising:
 a fracturing plug;   a setting tool operably connected to the fracturing plug;   a perforating gun assembled in the assembly;   a controller disposed in the assembly, the controller configured to sense location of the assembly and upon the assembly reaching a target location, the controller configured to autonomously cause setting of the fracturing plug and the firing of the gun.   
     
     
         13 . The assembly as claimed in  claim 12  further including a physical feature sensor. 
     
     
         14 . The assembly as claimed in  claim 12  further including a electromagnetic feature sensor. 
     
     
         15 . The assembly as claimed in  claim 12  further including a radiologic feature sensor. 
     
     
         16 . The assembly as claimed in  claim 12  further including a chemical feature sensor. 
     
     
         17 . The assembly as claimed in  claim 12  further including a braking system. 
     
     
         18 . The assembly as claimed in  claim 17  wherein the braking system includes an extendable arm. 
     
     
         19 . The assembly as claimed in  claim 12  further including a perforating gun interlock. 
     
     
         20 . A fracturing assembly for a borehole consisting of:
 a fracturing plug;   a setting tool operably connected to the fracturing plug;   a perforating gun assembled in the assembly;   a controller disposed in the assembly, the controller configured to sense location of the assembly and upon the assembly reaching a target location, the controller configured to autonomously cause setting of the fracturing plug and the firing of the gun.   
     
     
         21 . A borehole system having a fracturing assembly as claimed in  claim 12  therein. 
     
     
         22 . A borehole system having a fracturing assembly as claimed in  claim 20  therein.
