Wireline Tool Carrier Fluid Flow Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for positioning wireline tools in deviated wellbores are inefficient due to the need for multiple runs with coiled tubing, which are expensive and time-consuming, and often hindered by debris that requires initial cleaning operations.
Innovation Solution
A system and method utilizing a coiled tubing string with a wireline tool carrier that includes a fixed and floating stabilizer, allowing fluid to flow past the wireline tool, enabling debris removal and tool positioning in a single run, while also facilitating well stimulation or actuation of downhole equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional methods are used to position wireline tools in deviated wellbores, then multiple runs with coiled tubing are required, but this increases operational time and cost
Solution Approach 1:
The patent combines the cleaning tool and wireline tool into a single integrated assembly that can be deployed in one coiled tubing run. The cleaning tool is positioned above the wireline tool within the same tubular member, allowing both debris removal and wireline tool deployment to occur simultaneously during a single operation, thereby eliminating the need for separate cleaning runs and subsequent wireline tool deployment runs.
2Object-affected harmful factors
If a cleaning tool is used to remove debris before wireline tool deployment, then obstructions are cleared, but multiple separate runs are required
Solution Approach 1:
The cleaning tool and wireline tool are merged into a single integrated assembly where the cleaning tool is positioned above the wireline tool within the same tubular member. This allows both functions to be performed in one deployment, eliminating the need for separate cleaning operations and reducing the number of tool runs required.
Solution Approach 2:
The single tubular member assembly serves multiple functions: it acts as both a cleaning tool carrier and a wireline tool deployer. The assembly can perform debris removal, wireline tool deployment, and even well stimulation or actuation of downhole equipment, making it a multi-functional device that replaces multiple specialized tools and runs.
3Object-affected harmful factors
If fluid is pumped through coiled tubing and cleaning tool, then obstructions are broken up and removed, but the process is time-consuming
Solution Approach 1:
The patent enables continuous useful action by allowing fluid to flow through the coiled tubing and cleaning tool during the same operation that deploys the wireline tool. The cleaning function is not a separate preliminary step but occurs continuously alongside the wireline tool deployment, maximizing the utilization of the coiled tubing string and reducing total operation time.

Function Achieved in This Case
Enables efficient and cost-effective deployment of wireline tools in deviated wellbores by consolidating multiple runs into one trip, improving operational efficiency and allowing for simultaneous well intervention and stimulation operations.
Implementation Method 1
Fluid may be conveyed through the coiled tubing string and past the wireline tool through the flow path

AI summary
A carrier system may be used to position a wireline tool within a wellbore. The system includes a wireline tool carrier disposed on the end of a coiled tubing string. The wireline carrier tool includes a tubular member and stabilizers which secure the wireline tool within an internal passageway of the tubular member. The internal passageway defines a fluid flow path which facilitates fluid communication between the coiled tubing string and any device or wellbore portion below the wireline tool carrier. As the system is advanced within the wellbore fluid is conveyed around the wireline tool through the fluid flow path to remove obstructions that would otherwise inhibit the placement of the wireline tool within a deviated wellbore. Fluid conveyed through the system and around the wireline tool may also be used to perform various well stimulation and intervention functions.
