Frac devices are increasingly employed in modern wellbore processes to segregate zones during stimulation. Such dissolvable fracturing plugs offer a notable improvement over traditional retrievable plugs : they negate the necessity for a separate workover run to extract them. Instead , they slowly dissolve in the wellbore environment, typically through contact with chemicals used during post-frac phases . This strategy reduces finishing time and costs , while also mitigating the danger of injuring the borehole .
The Rise of Dissolvable Frac Plugs in Shale Operations
A growing demand for improved production in shale operations has fueled the adoption of dissolvable frac plugs. Previously , permanent plugs were utilized to isolate portions of the wellbore, involving costly and time-consuming mechanical retrieval processes. Yet, dissolvable plugs, which degrade and disappear during the production phase , provide a key advantage by eliminating this subsequent work. Such solutions are earning popularity among operators seeking to minimize expenses and accelerate well development.
