ABSTRACT:
Methods and tools are described to reduce sanding including the steps of fracturing the cement sheath in a localized zone around the casing and having the fractured zone act as sand filter between the formation and openings in the casing, with the openings being best pre-formed but temporarily blocked so as to allow a conventional primary cementing of the casing. The fracturing step can also be used for remedial operation to reopen blocked formation or screens.
