COIL SHIFTABLE PACKER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240011366 titled 'COIL SHIFTABLE PACKER
Simplified Explanation
The abstract of this patent application describes a packer assembly that includes several components such as a mandrel, a push sleeve, a shift sleeve, and a ratchet ring. These components work together to create a packer that can be actuated by a sliding sleeve.
- The mandrel is a central component of the packer assembly and contains an expandable packer element. It also has a ratchet section, a lower collet retaining shoulder, and longitudinal slots.
- The push sleeve is connected to the ratchet ring by shear pins. The ratchet ring is positioned between the push sleeve and the mandrel and engages with the mandrel's ratchet section.
- The shift sleeve consists of an inner shift sleeve and an outer shift sleeve. The inner shift sleeve is slidably disposed within the mandrel and has a lower collet. It also has a profile that can engage with a shifting tool. The outer shift sleeve slides around the mandrel and is connected to the inner shift sleeve with bolts that pass through the mandrel's longitudinal slots.
- The shift sleeve and push sleeve are movable between a running position and a released position, allowing the packer assembly to be actuated by a sliding sleeve.
Potential applications of this technology:
- Oil and gas industry: This packer assembly can be used in well completion and production operations to isolate different zones and control fluid flow.
- Geothermal energy: The packer assembly can be utilized in geothermal wells to enhance the efficiency and performance of the system.
Problems solved by this technology:
- Efficient isolation: The packer assembly provides a reliable and efficient method for isolating different zones in a well, preventing fluid communication between them.
- Controlled fluid flow: By actuating the packer assembly with a sliding sleeve, operators can control the flow of fluids in the well, optimizing production and minimizing unwanted fluid migration.
Benefits of this technology:
- Versatility: The packer assembly can be used in various wellbore configurations and can be easily adjusted and actuated as needed.
- Reliability: The use of ratchet sections, collet retaining shoulders, and shear pins ensures the packer assembly's reliability and stability during operation.
- Cost-effectiveness: The packer assembly's design and materials make it a cost-effective solution for well isolation and fluid control.
Original Abstract Submitted
a packer assembly includes (a) a mandrel bearing an expandable packer element, the mandrel having a ratchet section, a lower collet retaining shoulder, and defining a plurality of longitudinal slots; (b) a push sleeve connected to a ratchet ring by at least one shear pin, wherein the ratchet ring is disposed between push sleeve and the mandrel and engages the mandrel ratchet section; (c) a shift sleeve comprising an inner shift sleeve slidingly disposed within the mandrel and having a lower collet, the inner shift sleeve defining a profile for engaging a shifting tool, and an outer shift sleeve slidingly around the mandrel and connected to the inner shift sleeve with a plurality of bolts, wherein each bolt passes through a longitudinal slot defined by the mandrel; (d) wherein the shift sleeve and push sleeve is moveable between a running position and a released position. also disclosed are methods of using a packer actuated by a sliding sleeve.
