LINER HANGER SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18045618 titled 'LINER HANGER SYSTEM
Simplified Explanation
The abstract describes a liner hanger system for use in a subterranean well, which includes a spike with an annular seal that can transition between an initial state and an expanded state to seal different portions of the well.
- The liner hanger system comprises a well casing and a liner hanger.
- The liner hanger has a spike with an annular groove and an annular seal within the groove.
- The liner hanger can transition between an initial state and an expanded state.
- The spike and annular seal are designed to seal different portions of the well when the liner hanger is in the expanded state.
Potential Applications
This technology can be used in oil and gas drilling operations to isolate different sections of the wellbore.
Problems Solved
This liner hanger system helps prevent fluid migration between different zones in the well, improving well integrity and overall operational efficiency.
Benefits
- Enhanced wellbore isolation - Improved well integrity - Increased operational efficiency
Potential Commercial Applications
- Oil and gas drilling companies - Wellbore construction and completion services
Possible Prior Art
One possible prior art could be traditional liner hanger systems that do not have the expandable spike feature for sealing different wellbore sections.
Unanswered Questions
How does the liner hanger system handle high-pressure environments?
The article does not provide information on how the system performs under high-pressure conditions. This could be crucial for understanding its applicability in various drilling scenarios.
What is the expected lifespan of the liner hanger system?
The article does not mention the durability or expected lifespan of the liner hanger system. Understanding this aspect is essential for evaluating the long-term cost-effectiveness of the technology.
Original Abstract Submitted
A liner hanger system for use in a subterranean well is disclosed. The liner hanger system comprises a well casing and a liner hanger. The liner hanger comprises a spike extending in an annular ring around an outer perimeter of the liner hanger. The spike comprises an annular groove defined therein. The liner hanger further comprises an annular seal positioned at least partially within the annular groove. The liner hanger is expandable to transition between an initial state where the spike is not in contact with the well casing and an expanded state where the spike is in contact with the well casing. The spike and the annular seal are configured to seal an uphole well portion from a downhole well portion when the liner hanger is in the expanded state.
