Solution Overview

Problem

Existing methods for analyzing the contents of geological materials, particularly for detecting hydrocarbons, are limited by the need for high vacuum conditions which lead to gas loss and do not accurately reflect present-day fluid compositions in geologic formations.

Innovation Solution

A method that analyzes volatile substances from geological materials at various vacuum pressures, including low, medium, and high vacuum conditions, using a non-selective trap for condensable gases and mass spectrometry to analyze both condensable and non-condensable gases, allowing for the characterization of petroleum-associated regions and hydrocarbon deposits without the need for high vacuum.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high vacuum conditions are applied to analyze geological materials, then gas extraction efficiency is improved, but gas loss increases and measurement accuracy deteriorates

Engineering Contradiction:
Improvegas extraction efficiencyVSAvoidgas loss
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent applies parameter changes by transitioning from high vacuum conditions to atmospheric or near-atmospheric pressure conditions for gas extraction and analysis. This parameter change resolves the contradiction by eliminating gas loss while maintaining extraction efficiency, as gases are extracted into a headspace and analyzed without requiring high vacuum that causes gas escape and measurement errors.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If high vacuum conditions are applied for mass spectrometry analysis, then condensable gases can be analyzed, but non-condensable gases are lost and analysis accuracy deteriorates

Engineering Contradiction:
Improvecondensable gas analysis accuracyVSAvoidnon-condensable gas information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent applies segmentation by separating the analysis of condensable and non-condensable gases into distinct operational phases. Condensable gases are trapped and analyzed first under controlled conditions, then the system transitions to analyze non-condensable gases in the headspace without requiring high vacuum. This segmentation allows both gas types to be analyzed accurately without information loss.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by first extracting gases into a headspace under atmospheric conditions, then selectively trapping and analyzing condensable gases before analyzing non-condensable gases. This preliminary extraction step preserves all gases without loss, allowing subsequent selective analysis without compromising the integrity of non-condensable gas samples.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If fluid inclusions are analyzed under high vacuum, then material release is improved, but gas loss occurs and present-day fluid composition accuracy deteriorates

Engineering Contradiction:
Improvematerial release efficiencyVSAvoidpresent-day fluid composition accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent applies parameter changes by conducting fluid inclusion analysis under atmospheric or near-atmospheric pressure conditions rather than high vacuum. This parameter change maintains material release efficiency through alternative mechanisms while preserving present-day fluid compositions by preventing gas loss that occurs under high vacuum conditions.

AI summary

Methods for determining the hardness and/or ductility of a material by compression of the material are provided as a first aspect of the invention. Typically, compression is performed on multiple sides of a geologic material sample in a contemporaneous manner. Devices and systems for performing such methods also are provided. These methods, devices, and systems can be combined with additional methods, devices, and systems of the invention that provide for the analysis of compounds contained in such samples, which can indicate the presence of valuable materials, such as petroleum-associated hydrocarbons. Alternatively, these additional methods, devices, and systems can also stand independently of the methods, devices, and systems for analyzing ductility and/or hardness of materials.
