Super Expansion Dissolvable Plug (SEDP) is designed to solve severe downhole restriction challenges for unconventional well completion or workover. By reducing the plug OD substantially, SEDP improves the pass-thru ability of pump down assembly. Minimal plug OD, fully dissolvable features don't comprise the pressure holding up to10,000 psi. SEDP also comes with a patent pending “SMART-FIN” sleeve (Optional). When pump down starts, the pump ring around the setting sleeves opens up, reduce the fluid bypass, increase pump down efficiency and reduce fluids consumption.
