Fracturing Ball Retrieval Device and Method

摘要

A method and system for retrieving a fracturing ball in a wellbore casing. The system includes a wellbore retrieval tool comprising a tool body that is inserted into and transported along the wellbore casing. The tool is sized and configured to trap and hold the fracturing ball. When a hydraulic lock happens in the wellbore casing, the retrieval tool is lowered in a vertical section and the ball is flowed back along a horizontal section and captured by a trap in the retrieval tool. The retrieval tool may also be run in conjunction with a setting tool with a ball-in-place fracturing plug. In case of the hydraulic lock, the injection is tested following perforation with the retrieval tool still a location proximal to the ball, and the ball is immediately retrieved.
