SEALING ELEMENT OF ISOLATION DEVICE WITH INNER CORE AND OUTER SHELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 17938841 titled 'SEALING ELEMENT OF ISOLATION DEVICE WITH INNER CORE AND OUTER SHELL
Simplified Explanation
The patent application describes a zonal isolation device, such as a frac plug, for use in a wellbore to isolate different zones. The plug includes a slip system and a sealing element with an outer shell made of a material with a high Young's modulus and an inner core with a low Young's modulus. The outer shell prevents premature deformation and expansion of the sealing element during installation, while both the outer shell and inner core can disintegrate after a set period of time.
- Slip system and sealing element in zonal isolation device
- Outer shell with high Young's modulus and inner core with low Young's modulus
- Prevention of premature deformation and expansion
- Disintegration of outer shell and inner core after setting
Potential Applications
The technology can be used in oil and gas well operations for zonal isolation, hydraulic fracturing, and well stimulation.
Problems Solved
The technology solves the problem of premature deformation and expansion of sealing elements in zonal isolation devices, ensuring effective zonal isolation in wellbores.
Benefits
The benefits of this technology include improved zonal isolation, reduced risk of wellbore integrity issues, and enhanced well stimulation operations.
Potential Commercial Applications
Potential commercial applications include oil and gas well services, well completion operations, and well intervention services.
Possible Prior Art
One possible prior art could be traditional zonal isolation devices with fixed sealing elements that do not disintegrate after setting, leading to potential issues with wellbore integrity over time.
Unanswered Questions
How does the disintegration process of the outer shell and inner core affect the overall performance of the zonal isolation device?
The disintegration process of the outer shell and inner core may impact the long-term effectiveness of the zonal isolation device and its ability to maintain isolation between different zones in the wellbore.
What is the expected lifespan of the zonal isolation device before the outer shell and inner core disintegrate?
The expected lifespan of the zonal isolation device before the disintegration of the outer shell and inner core is crucial for determining the optimal timing for wellbore operations and maintenance.
Original Abstract Submitted
A treatment operation can be performed in a wellbore. A zonal isolation device, such as a frac plug, can be set within a tubing string in the wellbore to isolate one zone from another zone. The plug can include a slip system and a sealing element located circumferentially around an inner mandrel of the plug. The sealing element can include an outer shell that surrounds an inner core. The outer shell can be made from a material having a high Young's modulus, while the inner core can have a very low Young's modulus. The outer shell can prevent premature deformation and expansion of the sealing element during run in. The outer shell and inner core can wholly or partially disintegrate in a desired a period of time after setting of the plug in the tubing string.
