摘要：
Methods and compositions are provided that utilize pumice and various additives. An embodiment provides a method of remedial cementing in a subterranean formation comprising: providing a lightweight settable composition comprising pumice, a calcium activator, and water, wherein the lightweight settable composition has a density of less than about 13.5 pounds per gallon and is free of Portland cement; and using the lightweight settable composition in a remedial cementing method to seal one or more voids in a well bore. Also provided are pumice-containing remedial compositions and systems for remedial cementing.
