Frac devices are commonly implemented in modern borehole operations to isolate sections during stimulation. These dissolvable fracturing devices offer a significant improvement over legacy retrievable barriers: they eliminate the requirement for a separate workover operation to retrieve them. Rather, they slowly degrade in the wellbore environment, typically through read more interaction with acids used during completion phases . This strategy minimizes operational length and expenditures, while also avoiding the hazard of damaging the borehole .
The Rise of Dissolvable Frac Plugs in Shale Operations
The increasing need for improved production in shale plays has spurred the rise of dissolvable frac plugs. In the past, permanent plugs were utilized to isolate sections of the wellbore, necessitating costly and protracted mechanical removal processes. However , dissolvable plugs, which degrade and disappear during the production period, offer a substantial benefit by eliminating this subsequent work. These solutions are earning traction among operators seeking to minimize expenditures and accelerate well development.
