Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In subterranean formation operations, existing technologies fail to effectively detect and remove deleterious analytes such as mercury and hydrogen sulfide from wellbore fluids, which can cause equipment failures and safety concerns.
Innovation Solution
The use of reactive filter materials in formation testers that sorb and detect analytes, including mercury and hydrogen sulfide, by being strategically placed in fluid flow lines to absorb or adsorb these substances before they exit the formation tester, thereby preventing exposure and allowing for accurate measurement and analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reactive filter material is added to the formation tester, then the ability to detect and remove deleterious analytes is improved, but the device complexity increases
Solution Approach 1:
The patent combines the filtration function and detection function into a single integrated reactive filter material component. The filter material both removes deleterious analytes through sorption and provides detection capability through sensors embedded within or in communication with the filter material, eliminating the need for separate filtration and detection systems.
Solution Approach 2:
The reactive filter material serves multiple functions simultaneously: it acts as a physical barrier to particulates, chemically sorbs deleterious analytes like mercury and hydrogen sulfide, and provides a medium for sensor-based detection. This multi-functionality reduces the overall system complexity while improving reliability.
2Object-affected harmful factors
If reactive filter material is strategically placed in fluid flow lines, then safety and equipment reliability are improved by preventing exposure, but the device complexity increases
Solution Approach 1:
The reactive filter material is strategically positioned in the fluid flow line upstream of the outlet and sample chamber to preemptively sorb deleterious analytes before they can exit the formation tester or contaminate samples. This preliminary action prevents harmful exposures and equipment damage before they occur.
Solution Approach 2:
The reactive filter material acts as an intermediary component between the wellbore fluid and the formation tester's internal components and external environment. It mediates the interaction by selectively removing harmful analytes while allowing safe fluids to pass through, protecting both equipment and operators.
3Measurement precision
If reactive filter material is used to sorb analytes, then measurement precision is improved by allowing accurate analysis, but the device complexity increases
Solution Approach 1:
The reactive filter material creates localized zones of high analyte concentration through selective sorption, which enhances the sensitivity and precision of detection sensors. By concentrating deleterious analytes at specific locations within the filter material, the system achieves more accurate measurements without requiring complex detection equipment throughout the entire system.

AI summary
A formation tester comprises a body having an outlet; a probe extendable from the body and having a sealing pad; and a flow line within the body, wherein the flow line has an entry end connectable to the probe and has an exit end connectable to the outlet in the body; and a reactive filter material in the flow line downstream of the entry end of the flow line, wherein the reactive filter material sorbs and entraps an analyte in a wellbore fluid.
