Solution Overview

Problem

Drilling fluid circulation systems lack real-time monitoring of drilling fluid parameters, leading to infrequent and inaccurate measurements, which can result in borehole instability and well control issues due to the absence of sensors, and retrofitting with sensors is costly and not commonly practiced.

Innovation Solution

A standalone sensor package is designed to be easily integrated into existing drilling fluid circulation systems, featuring sensors and a processor that continuously monitor drilling fluid parameters, compare them to target profiles, and adjust the fluid profile dynamically to maintain optimal conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If no sensors are installed in the drilling fluid circulation system, then the system remains simple and cost-effective, but real-time monitoring of drilling fluid parameters cannot be achieved

Engineering Contradiction:
Improvedrilling fluid parameter monitoringVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

A portable container unit with integrated sensors serves as an intermediary device that temporarily couples to the drilling fluid circulation system. This mediator enables real-time monitoring of drilling fluid parameters without permanently modifying or complicating the main system architecture, resolving the contradiction between measurement capability and system simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The monitoring function is extracted from the main drilling fluid circulation system and placed in a separate, portable container unit. This extraction allows the monitoring capability to be added without increasing the complexity of the primary system, as the sensors and processing are contained in a standalone module that can be easily attached and removed.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If sensors are retrofitted into the drilling fluid circulation system, then real-time monitoring capability is achieved, but the cost and complexity increase significantly

Engineering Contradiction:
Improveborehole stabilityVSAvoidsystem cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The portable container unit with sensors is designed as a cost-effective, temporary monitoring solution rather than a permanent installation. This approach uses more economical sensors and housing that can be deployed for the duration of drilling operations and then removed, reducing the overall cost compared to permanently retrofitting expensive sensors into the circulation system while still achieving the reliability needed for borehole stability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The portable container acts as a cost-isolating intermediary, containing all sensor and processing costs within a separate, replaceable unit. This allows the main drilling system to remain simple and cost-effective while still achieving reliable monitoring through the added portable module, resolving the contradiction between reliability and manufacturing cost.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If manual sampling and testing of drilling fluid is performed, then equipment complexity remains low, but measurement accuracy and frequency are insufficient

Engineering Contradiction:
Improvedrilling fluid parameter accuracyVSAvoidmonitoring automation
Core Design Contradiction:
Measurement precisionVSExtent of automation

Solution Approach 1:

The portable container unit incorporates sensors that continuously measure drilling fluid parameters and provide real-time feedback about mud weight, composition, and other critical properties. This automated feedback system replaces manual sampling and testing, achieving high measurement precision and frequency while maintaining reasonable automation levels through a self-contained monitoring unit that requires minimal operator intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The sensor package within the portable container is designed to autonomously monitor and record drilling fluid parameters without requiring manual operation. The system self-regulates the monitoring process, automatically measuring parameters and generating data, which eliminates the need for frequent manual sampling while achieving superior measurement accuracy and continuity.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If multiple sensors are integrated into a portable container unit, then real-time monitoring is achieved without permanent system modification, but the container design and integration complexity increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The portable container unit is designed with universal coupling mechanisms that can interface with standard drilling fluid circulation system components. The container integrates multiple sensors (density, temperature, composition) into a single multi-functional module that can be attached to various positions in the circulation system, providing adaptability across different drilling operations while managing integration complexity through standardized connection interfaces.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A system includes a container unit and a processor. The container unit includes a first fluid pathway having an inlet configured to couple to a first component of a drilling fluid circulation system, and having an outlet configured to couple to a second component of the drilling fluid circulation system. The container unit also includes a second fluid pathway having an inlet configured to couple to a third component of the drilling fluid circulation system, and having an outlet configured to couple to the third component. The container unit includes a first sensor coupled to the first fluid pathway and a second sensor coupled to the second fluid pathway. The processor is configured to determine a drilling fluid profile based on data from the sensors, and compare the determined drilling fluid profile to a target drilling fluid profile to determine an adjustment for an actual drilling fluid profile.
