Retrievable Fracture Plugs : A Detailed Review
Dissolvable frac barriers represent a notable improvement in borehole construction procedures. These specialized tools are engineered to temporarily seal sections of a borehole during hydraulic operations , and then dissolve completely after their task is completed . This avoids the need for a subsequent run to extract the device , thereby minimizing expenditures and optimizing operational effectiveness . They are generally composed of plastic materials that break down under specific factors such as temperature and chemical interaction.
Understanding Dissolvable Frac Plug Technology
Dissolvable plug represents a significant innovation in hydraulic fracturing operations. These components are created to be initially set within a wellbore to isolate zones and redirect materials during the stimulation process. Unlike conventional, mechanically-retrievable barriers, dissolvable plugs are constructed from composites that eventually degrade and dissolve upon exposure to wellbore environments. This eliminates the need for costly and protracted retrieval operations , minimizing downtime and maximizing yield.
