Dissolvable frac plugs are temporary barriers used in hydraulic fracturing operations to isolate different sections of a wellbore. They are designed to dissolve under specific conditions, such as exposure to certain chemicals or changes in pressure and temperature.

Here's how they work:


  1. Placement:The dissolvable frac plug is inserted into the wellbore at the desired location. It is typically placed using a wireline unit, which lowers the plug into the well on a wireline.

  2. Setting:Once in place, the plug is "set" or activated to seal the wellbore. This may involve pumping a specific fluid or applying pressure to the plug.

  3. Hydraulic Fracturing:The section of the wellbore above the plug is then subjected to hydraulic fracturing. This involves pumping a high-pressure mixture of water, sand, and chemicals into the well to create fractures in the rock formation and increase oil or gas production.

  4. Dissolution:After the fracturing operation is complete, the plug is designed to dissolve. This may occur naturally due to changes in pressure, temperature, or exposure to specific chemicals in the wellbore.

  5. Production:Once the plug has dissolved, oil or gas can flow from the fractured section of the wellbore to the surface.


Why use dissolvable frac plugs?

  • Efficiency:Dissolvable frac plugs can improve the efficiency of hydraulic fracturing operations by allowing operators to isolate different sections of the wellbore and focus fracturing efforts on specific areas.

  • Cost-effectiveness:They can be more cost-effective than traditional mechanical plugs, as they do not require additional operations to remove them from the wellbore.

  • Safety:Dissolvable frac plugs can help to improve safety by reducing the risk of wellbore leaks or uncontrolled fluid flow.


Dissolvable frac plugs are a valuable tool in the oil and gas industry, providing a safe and efficient way to isolate different sections of a wellbore during hydraulic fracturing operations.
