摘要： A well completion and workover method wherein a subterranean formation is contacted with a high density, nondamaging treating fluid which comprises a saturated, aqueous solution having finely divided particles of a water soluble salt suspended therein. The saturated aqueous saline solution should have a density of at least about 1.2 g/cc and the suspended salt particles should be present in sufficient quantities to substantially increase the overall density of the treating solution. The preferred fluid comprises a suspension of pulverized sodium chloride in a saturated calcium chloride solution. Dispersants and viscosifiers can be added in minor amounts to help maintain the salt particles in suspension.
