SUBSURFACE SAMPLING TOOL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18061002 titled 'SUBSURFACE SAMPLING TOOL
Simplified Explanation: The downhole sampling tool described in the patent application is designed to draw formation fluid into a sampling vessel by selectively engaging a closure member with an opening in the tool body. The closure member is biased to remain closed but can open in response to increased hydraulic pressure, allowing the formation fluid to flow into the sampling vessel.
- Key Features and Innovation:
- Tool body with opening for drawing formation fluid
- Sampling vessel to receive formation fluid
- Closure member to control flow of fluid
- Biasing mechanism to open closure member at a threshold pressure
Potential Applications: The downhole sampling tool can be used in oil and gas exploration, geothermal energy extraction, and environmental monitoring to collect and analyze formation fluids for various purposes.
Problems Solved: This technology addresses the challenge of efficiently and accurately sampling formation fluids in downhole environments where pressure conditions can vary.
Benefits:
- Improved sampling accuracy
- Enhanced data collection in challenging downhole environments
- Increased efficiency in fluid analysis processes
Commercial Applications: The downhole sampling tool can be utilized by oil and gas companies, geothermal energy producers, and environmental monitoring agencies to optimize resource extraction and environmental impact assessments.
Prior Art: Prior art related to downhole sampling tools includes various designs for sampling devices in downhole environments, but the specific biasing mechanism described in this patent application appears to be a novel feature.
Frequently Updated Research: Ongoing research in downhole sampling technologies may lead to advancements in sampling efficiency, data analysis capabilities, and environmental monitoring applications.
Questions about Downhole Sampling Tool:
- Question 1: How does the biasing mechanism in the sampling tool respond to changes in hydraulic pressure?
- Question 2: What are some potential challenges in implementing this technology in different downhole environments?
Original Abstract Submitted
A downhole sampling tool includes a tool body defining an opening therein for drawing a formation fluid into the downhole sampling tool. At least one sampling vessel is carried in the tool body and is operatively coupled to the opening to receive the formation fluid therein. A closure member is selectively engageable with the opening to prohibit flow of the formation fluid through the opening, and a biasing mechanism is operably coupled to the closure member. The biasing mechanism biases the closure member into engagement with the opening and is responsive to an increase in hydraulic pressure on the exterior of the sampling tool to a predetermined threshold pressure to permit movement of the closure member away from the opening and permit flow of the formation fluid through the opening and into the sampling vessel.
