Vertechs Dissolvable Plug Empowers Re-Fracturing in Mature Wells
In China, more and more mature wells require re-stimulation to extend their productive life, this requires utilizing expandable tubular patching to restore wellbore integrity, followed by plug-and-perf operations to create complex fracture networks, thereby enlarging stimulated reservoir volume and enhancing well productivity. However, this technique introduces operational challenges including irregular wellbore ID at plug setting depth and reduced inner diameter at liner hanger, which potentially smaller than standard plug OD
