Abrasive Perforator and Plug Dispenser for Single-Trip Well Completion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current well completion techniques face challenges in efficiently stimulating and isolating multiple formation zones in a single trip of the bottom hole assembly, leading to inefficiencies and increased operational costs.
Innovation Solution
The system employs a bottom hole assembly equipped with an abrasive perforator and a plug dispenser tool, allowing for the simultaneous perforation, stimulation, and isolation of multiple zones by forming abrasive jets to create perforations and using plugs to block fluid flow after stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional well completion techniques are used to stimulate and isolate multiple formation zones, then operational complexity and time increase, but the ability to complete multiple zones in a single trip is limited
Solution Approach 1:
The bottom hole assembly is divided into multiple independent functional modules including an abrasive perforator for creating perforations, a stimulation device for injecting fracturing fluid, and a plug dispenser for isolating zones. These segmented components can be independently controlled and activated at different depths, enabling multiple zones to be processed in a single trip while reducing operational complexity
Solution Approach 2:
The bottom hole assembly is designed as a multi-functional system that can perform perforation, stimulation, and isolation operations within a single integrated unit. This universal device eliminates the need for multiple separate trips or equipment configurations, thereby reducing operational time while increasing the number of zones that can be completed per trip
2Productivity
If conventional well completion techniques are used, then operational costs increase due to multiple trips, but efficiency remains low
Solution Approach 1:
The system merges perforation, stimulation, and isolation operations into a single integrated bottom hole assembly that can execute all functions during one trip. This consolidation eliminates the need for multiple separate trips and equipment deployments, thereby reducing operational costs while simultaneously improving completion efficiency through streamlined operations

AI summary
A bottom hole assembly can include an abrasive perforator with at least one nozzle configured to direct an abrasive jet outward from the abrasive perforator, and a plug dispenser tool configured to discharge at least one plug via a plug discharge port into an annulus surrounding the plug dispenser tool. A method of completing a well can include deploying a bottom hole assembly into a wellbore, perforating at least one zone with an abrasive perforator of the bottom hole assembly, and then discharging at least one plug from a plug discharge port of a plug dispenser tool of the bottom hole assembly. The discharging step can include the plug displacing from an internal flow passage of the bottom hole assembly to an annulus formed between the bottom hole assembly and the wellbore.
