Solution Overview

Problem

Legacy autocalcimeters used in geoservices are limited by their standalone nature, which prevents real-time data connectivity to acquisition systems and lacks a continuous shaking or agitation option, leading to inaccurate and less precise measurements of carbonate content in rock samples.

Innovation Solution

The integration of a calcimeter with a laboratory shaker and an acquisition system allows for continuous shaking and real-time pressure measurement, enabling more accurate and precise determination of carbonate content, including calcite and dolomite, in rock samples.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If legacy autocalcimeters are used as standalone units, then device simplicity is maintained, but real-time data connectivity and measurement precision are limited

Engineering Contradiction:

Improvecarbonate content measurement precisionVSAvoidsystem integration complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the calcimeter with the laboratory shaker into an integrated system, allowing the calcimeter to be positioned on the shaker platform. This merging enables continuous shaking during pressure measurement, improving carbonate content measurement precision while maintaining manageable system complexity through modular integration rather than complete system redesign

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated system serves multiple functions: the shaker provides both sample agitation and serves as a platform for the calcimeter, while the acquisition system handles both data acquisition and real-time processing. This multi-functionality improves measurement precision without proportionally increasing device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If continuous shaking is implemented during measurement, then measurement precision and reaction completeness are improved, but device complexity and operational complexity increase

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system enables self-service operation where the integrated calcimeter and shaker automatically coordinate their functions. The acquisition system automatically records pressure data while the shaker maintains continuous agitation, eliminating the need for manual intervention and maintaining ease of operation despite the enhanced measurement capabilities

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements continuous shaking throughout the entire measurement duration, ensuring constant sample-acid contact and complete reaction. This continuous action improves measurement precision while the automated control maintains operational simplicity by eliminating the need for manual shaking interruptions

Inventive Principle:

Solution Approach 1:

The system employs mechanical vibration through continuous shaking of the calcimeter platform during measurement. This vibration ensures thorough mixing of the rock sample with HCl acid, improving reaction completeness and measurement accuracy while the automated control maintains operational simplicity

Inventive Principle:

AI summary

Systems and methods may determine carbonate content in rock samples and may include shaking a calcimeter having a reaction chamber including at least one pressure sensor and an acid cup with a rock sample therein and recording a first pressure value at or after a first time duration of shaking, wherein the first pressure value is indicative of first gas pressure within the reaction chamber at or after the first time duration of shaking. The systems and methods may also record a second pressure value at or after a second time duration of shaking, wherein the second pressure value is indicative of second gas pressure within the reaction chamber at or after the second duration of shaking, and calculate a carbonate content in the rock sample based on at least one of the recorded first pressure value and the recorded second pressure value.
