Tubular Indicator System for Tool Position Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In tubular systems, tools often become stuck or move slowly when trying to reach a desired position, wasting time and resources due to the tight fit between the tool and the tubular, and there is a need for a method to efficiently verify the tool's arrival at the intended location.
Innovation Solution
An indicator system comprising a body with a sensor and signal generator that detects the tool's arrival and sends a notification, which can include emitting a substance or signal, and features like wings and stabilizers to facilitate smooth passage and secure positioning within the tubular.

Engineering Contradiction Analysis
1Reliability
If a tool is run through a tubular to a desired position, then the tool can reach the intended location, but the tool may become hung and the rate of running may slow, consuming valuable time
Solution Approach 1:
The indicator includes a sensor that detects when the tool has reached the desired position and a signal generator that sends notification of this detection. This feedback mechanism allows real-time verification of tool placement without requiring time-consuming trial-and-error or manual checking, thereby improving reliability while minimizing time loss.
Solution Approach 2:
The indicator acts as an intermediary device between the tool and the tubular system. It includes features such as wings and stabilizers that facilitate smooth passage through the tubular while maintaining reliable contact detection, serving as a mediator that enables reliable tool placement verification without significant time delay.
2Reliability
If the tool fits tightly within the tubular, then the tool can be securely positioned, but the tool may become stuck and require additional force or time to move through
Solution Approach 1:
The indicator is divided into functional segments: a body for passage, wings for guidance, stabilizers for positioning, and detection components for verification. This segmentation allows each component to address specific challenges - the wings and stabilizers facilitate easy passage while the sensor and signal generator ensure reliable positioning detection.
Solution Approach 2:
The indicator features dynamic elements such as wings that can adjust during passage and stabilizers that deploy at the desired position. These dynamic features enable the indicator to adapt to the tubular geometry, facilitating smooth passage while ensuring reliable contact when the tool reaches the intended location.

AI summary
An indicator including a body configured to be run within a tubular from a first portion to a second portion of the tubular. A sensor disposed at the body configured to detect when a tool run through the tubular has reached the body. A signal generator configured to send notification that the tool has reached the body; and a plunger configured to cause the signal generator to send notification upon being urged relative to the body. A method of verifying a tool.
