Solution Overview

Problem

Apparatuses for sensing wellbore characteristics are not entirely reliable for collecting and providing data representative of wellbore conditions.

Innovation Solution

A wellbore characteristic measurement assembly comprising a dispensing mechanism and a plurality of measurement apparatuses, each mountable to the mechanism in a releasably retained condition, configured for serial dispensing into the wellbore, equipped with sensors and a coupler for releasable retention to wellbore features, and a chemical tracer apparatus for releasing tracers into wellbore fluids, allowing for accurate data collection and modulation of material flow based on sensed characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional sensing apparatuses are used for wellbore measurement, then device complexity is reduced, but measurement precision and reliability deteriorate

Engineering Contradiction:

Improvewellbore condition data accuracyVSAvoidmeasurement assembly structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The measurement system is divided into multiple independent measurement apparatuses (first, second, third apparatuses) that can be serially dispensed into the wellbore. Each apparatus independently measures specific parameters, and their results are combined to achieve comprehensive and accurate wellbore characterization, resolving the contradiction between measurement precision and device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A chemical tracer apparatus is introduced as an intermediary component that releases tracers into wellbore fluids. These tracers enhance the measurability of fluid characteristics by sensors, improving measurement precision without requiring direct contact between sensors and challenging fluid conditions, thus resolving the measurement reliability issue.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If multiple measurement apparatuses are deployed serially, then measurement precision improves, but device complexity and ease of operation worsen

Engineering Contradiction:

Improvewellbore condition data accuracyVSAvoiddeployment and retrieval process

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

Multiple measurement apparatuses and a chemical tracer apparatus are merged into a single integrated measurement assembly that can be deployed as one unit. The assembly includes a dispensing mechanism that serially releases individual measurement apparatuses into the wellbore, simplifying the deployment process while maintaining multiple sensing capabilities for high measurement precision.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The measurement apparatuses are designed with self-retention features including releasable couplers that automatically engage with wellbore features (such as tubing external surfaces) upon deployment. This self-service mechanism eliminates the need for complex manual deployment operations, improving ease of operation while maintaining the benefits of multiple serially deployed sensors.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If measurement apparatuses are made retrievable, then adaptability improves, but reliability of data collection worsens

Engineering Contradiction:

Improveretrievability and redeployment capabilityVSAvoiddata collection reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Measurement apparatuses are equipped with releasable couplers designed to automatically engage with wellbore features during the deployment process itself. This preliminary action ensures secure attachment before data collection begins, maintaining data reliability. The same couplers can later be released to enable retrieval and redeployment, providing adaptability without compromising data collection reliability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The measurement system transitions from a static, permanently installed configuration to a dynamic, retrievable system. Measurement apparatuses use controllable releasable couplers that can engage and disengage based on operational requirements. This dynamic capability allows the system to adapt to different wellbore conditions and deployment scenarios while maintaining reliable data collection through secure engagement during measurement periods.

Inventive Principle:

Principle #15Dynamics
