Disappearing expandable cladding

摘要: Perforations in an existing borehole are covered with expandable clad or elongated tubular that is expanded on location the expansion equipment then removed. The made of a disintegrating material such as controlled electrolytic known CEM and into position to cover perforations. One more plugs run perforating guns set moved away from plug fired make new perforation. After each perforation ball delivered isolate portion well perforations treated fracturing another operation. Over time exposure fluids temperatures disintegrates original drift diameter regained so subsequent production injection not impeded.
