Method and apparatus for downhole production zone

This invention describes a specialized tool lowered into a well to test how much fluid a production zone can produce, all without bringing any fluid to the surface. The tool uses seals to isolate the production zone, allowing its fluid to flow into a central pipe. It also has a separate seal for an injection zone and includes pressure sensors to monitor both zones.

Why it matters: Downhole sensor reliability and real-time data processing for reservoir characterization have advanced significantly since 2001. This could make the in-situ testing and pressure analysis more precise and cost-effective, aligning with modern environmental and operational efficiency goals.
