Frac plugs are temporary isolation barriers that have enough strength to hold back the fracture pressures and prevent fracturing fluids from flowing into unwanted zones. A frac plug is inserted above that one section in which hydraulic fracturing took place. The plug seals off the already fractured zone from the rest of the well and allows for pressure to be maintained when pumping fluids through perforated casing into already fracked rock. A check valve also called a frac plug is run in and pumped among the proppant to compartmentalize stages for multi-stage stimulation treatments. During stimulation, they would isolate the lower zone but flow from below is allowed for well clean-up after pumping has ended.

Main Purpose
The primary function of a frac plug is to:
- Isolate perforated zones
- Contain fracture treatment fluids
- Control pressure
- Prevent fluid migration between zones
- Components
A typical frac plug consists of:
- Upper slip (anchors to casing)
- Seal element (rubber or elastomer)
- Lower slip (anchors to liner or casing)
- Setting tool (deploys plug)
Operation
- Run-in-hole (RIH) with setting tool
- Position at desired depth
- Set plug (expand slips, seal element)
- Perform fracture treatment
- Remove plug (drill-out or retrieve)

The frac plug plays a vital role in ensuring the effectiveness and efficiency of hydraulic fracturing operations. Some of the frac plugs offered by Thankful Material suitable with your complex well solutions are as follow
Thankful Single Slip Soluble Bridge Plug
Single slip dissolvable bridge plugs are the kind of bridge plugs made of all-metal materials, but some or all of its components can be dissolved under specific conditions, such as contacting with specific dissolvents or achieving specific environmental conditions.
Thankful Double Slip Soluble Bridge Plug
Double slip dissolvable bridge plug is a kind of down-hole tool that uses double kava structure for support and dissolvable material to achieve plugging and unplugging.
Thankful Blocking Composite Bridge Plug
Blocking bridge plugs are mainly used for temporary or permanent blocking of oil, gas, and water layers. They can be used specifically for production and channeling, water plugging, fracturing, acidification, testing and other constructions.
Thankful Dissolvable Frac Plug
A dissolvable bridge plug is a device that constructs a dissolvable controlled barrier in the well-bore, usually made of a soluble material. It is capable of sealing off fluid passages in the well-bore when needed and restoring access by dissolution when no longer needed.
Thankful Cast Iron Bridge Plug
It is widely used in the process of oilfield exploration and development, especially in the construction of oil and water wells for layered fracturing, layered acidizing and layered oil testing, it is used to seal the lower well section to ensure the safety and effectiveness of the operation.
Thankful Material also offers all other types of frac plugs in the industry for more details check our website.
