Downhole intervention and completion drone and methods of use

Abstract

One method includes temporarily sealing and isolating a portion of a wellbore with a reusable sealing and isolation element, performing a fracturing process in the portion of the wellbore that is isolated, and after the fracturing process is complete, unsealing or de-isolating the portion of the wellbore by temporarily changing a configuration of the reusable sealing and isolation element. Use of the reusable sealing and isolation element may reduce, or eliminate, the need for remediation operations, such as the removal of sealing plugs.

What is claimed is: 
     
         1 . A method, comprising:
 temporarily sealing and isolating a portion of a wellbore with a reusable sealing and isolation element;   performing a fracturing process in the portion of the wellbore that is isolated; and   after the fracturing process is complete, unsealing or de-isolating the portion of the wellbore by temporarily changing a configuration of the reusable sealing and isolation element.   
     
     
         2 . The method as recited in  claim 1 , wherein the method is performed autonomously by a well intervention drone. 
     
     
         3 . The method as recited in  claim 2 , wherein the well intervention drone comprises a perforating module that performs the fracturing process. 
     
     
         4 . The method as recited in  claim 2 , wherein the well intervention drone autonomously mitigates sand and debris screen outs. 
     
     
         5 . The method as recited in  claim 2 , further comprising wirelessly charging a battery of the well intervention drone while the well intervention drone is in the wellbore. 
     
     
         6 . The method as recited in  claim 2 , wherein the well intervention drone, while positioned in the wellbore, gathers data before, during, and/or, after, the fracturing process. 
     
     
         7 . The method as recited in  claim 2 , wherein the well intervention drone, while positioned in the wellbore, communicates data to a surface location. 
     
     
         8 . The method as recited in  claim 1 , further comprising moving the entire reusable sealing and isolation element to another location in the wellbore, and isolating the wellbore at another location with the reusable sealing and isolation element. 
     
     
         9 . The method as recited in  claim 1 , wherein temporarily sealing and isolating a portion of the wellbore with the reusable sealing and isolation element, comprises temporarily changing the configuration of the reusable sealing and isolation element relative to a configuration of the reusable sealing and isolation element when the wellbore is sealed and isolated with the reusable sealing and isolation element. 
     
     
         10 . The method as recited in  claim 1 , wherein after the wellbore is de-isolated, no post-remediation of the reusable sealing and isolation element is required at the site where the reusable sealing and isolation element had been positioned. 
     
     
         11 . A method, comprising:
 deploying a well intervention drone to a downhole location; and   using the well intervention drone to collect data uphole and/or downhole of a reusable sealing and isolation element while the reusable sealing and isolation element is engaged with the drone and/or disengaged from the drone.   
     
     
         12 . The method as recited in  claim 11 , where data collection is performed pre-frac, during frac, and/or post-frac. 
     
     
         13 . The method as recited in  claim 11 , where the data collected comprises data about a wellbore environment, wellbore conditions, and/or, wellbore activity. 
     
     
         14 . The method as recited in  claim 11 , wherein the data is collected autonomously by the well intervention drone. 
     
     
         15 . The method as recited in  claim 11 , wherein the data is collected while the well intervention drone is unconnected to the surface or equipment on the surface. 
     
     
         16 . The method as recited in  claim 11 , wherein data collection is performed autonomously by the well intervention drone, and the data collection begins when the well intervention drone is at its deepest location in a well, and data collection continues at least part of a time during which the well intervention drone moves away from the deepest location.
