Fracture devices are rapidly employed in modern reservoir procedures to isolate sections during hydraulic fracturing . Such dissolvable frac barriers offer a significant improvement over traditional retrievable plugs : they negate the requirement for a dedicated workover operation to extract them. Instead , they gradually degrade in the reservoir environment, typically through exposure with chemicals used during post-frac phases . This strategy minimizes operational duration and costs , while also mitigating the hazard of injuring the formation.
The Rise of Dissolvable Frac Plugs in Shale Operations
The expanding pressure for improved production in shale plays has driven the adoption of dissolvable frac plugs. In the past, permanent plugs were employed to isolate zones of the wellbore, requiring costly and lengthy mechanical removal processes. Yet, dissolvable plugs, which degrade and disappear during the production phase , present a key benefit by eliminating this additional work. This approaches are gaining popularity among operators seeking to minimize costs and speed up well completion .
Degradable Frac Plugs : Advantages and Obstacles
Dissolvable frac plugs provide a novel solution for wellbore completion, largely in hydraulic fracturing operations . These plugs are created to reliably seal portions of the wellbore during fracturing, then entirely degrade under specific conditions , usually exposure to fluids or temperature .
