==SACRIFICIAL TOOL FOR PLUGGING AND ABANDONING A WELLBORE AND METHODS THEREOF - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240301765 titled 'SACRIFICIAL TOOL FOR PLUGGING AND ABANDONING A WELLBORE AND METHODS THEREOF

'''Simplified Explanation:'''
The patent application describes a method involving the use of a sacrificial tool in a wellbore to address downhole tool sticking issues.

* The sacrificial tool is conveyed into the wellbore on a conveyance.
* It includes an overshot fishing tool, tubing, and a liner hanger.
* The downhole tool stuck in the wellbore is engaged with the sacrificial tool.
* Cement is circulated through the sacrificial tool and the downhole tool to seal the annulus.

'''Key Features and Innovation:'''
* Conveyance of sacrificial tool into wellbore
* Use of overshot fishing tool, tubing, and liner hanger
* Engagement of downhole tool with sacrificial tool
* Circulation of cement to seal annulus

'''Potential Applications:'''
This technology can be applied in oil and gas drilling operations to address downhole tool sticking issues.

'''Problems Solved:'''
The technology solves the problem of downhole tool sticking in wellbores, which can hinder drilling operations.

'''Benefits:'''
* Improved efficiency in drilling operations
* Prevention of costly delays due to downhole tool sticking
* Enhanced wellbore integrity through effective cement sealing

'''Commercial Applications:'''
Potential commercial applications include oil and gas drilling companies looking to optimize their operations and reduce downtime.

'''Questions about the Technology:'''
1. How does the sacrificial tool prevent downhole tool sticking in the wellbore?
2. What are the key components of the sacrificial tool and how do they work together to address the issue of downhole tool sticking?

'''Frequently Updated Research:'''
There may be ongoing research in the field of wellbore integrity and downhole tool management that could be relevant to this technology. 

By optimizing the conveyance of sacrificial tools in wellbores, this technology offers a practical solution to downhole tool sticking issues, benefiting oil and gas drilling operations.


==Original Abstract Submitted==

a method includes conveying a sacrificial tool into a wellbore on a conveyance, the wellbore penetrating one or more subterranean formations and the sacrificial tool including an overshot fishing tool, a tubing operatively coupled to and extending from the overshot fishing tool, and a liner hanger arranged at an upper end of the tubing. an uphole end of a downhole tool is received within with the overshot fishing tool, the downhole tool being stuck in the wellbore adjacent the one or more subterranean formations. the uphole end of the downhole tool is sealingly engaged, and a cement is subsequently circulated through the sacrificial tool and the downhole tool and discharged into an annulus defined between the downhole tool and an inner wall of the wellbore.
