Frac plugs are temporary downhole isolation tools used during hydraulic fracturing and plug-and-perf completion methods. They provide a mechanical barrier within the wellbore to segregate stages of the well for targeted stimulation.
By isolating a section above each plug, operators can introduce fracturing fluid into a specific zone at high pressure and ensure that treatment is focused where it will be most effective. In multi-stage fracking operations, frac plugs are set sequentially from bottom to top. After each stage is fractured, the plug serves as a barrier so the next interval can be perforated and stimulated.
Once treatments are complete, frac plugs are typically removed or drilled out to allow hydrocarbons to flow freely into the well.
Frac plugs are run into the wellbore on coiled tubing, wireline, or other conveyance methods. They are set at the desired depth where isolation is required. Once positioned, the plug expands or anchors against the casing wall, creating a seal that holds back pressure and fluids.
After setting a plug and isolating the interval above it, perforation guns open communication with the reservoir. High-pressure fracturing fluids are then pumped into that isolated section. The plug maintains isolation until the stimulation stage is complete, at which point it may be removed mechanically or dissolved naturally if a dissolvable design is selected.
Delta Oil Tools supports operators with frac plug solutions that match the pressure and isolation needs of each well design, ensuring that fluid placement and stimulation are executed as intended.
