Abstract:
The present invention is directed to plug-and-abandon operations that use plugging compositions comprising cement kiln dust, pumicite, and/or lime. An embodiment includes a method of plugging a well bore for abandonment comprising: placing a plugging composition in the well bore, the plugging composition comprising: cement kiln dust in an amount of about 5% to about 100% by weight of cementitious components, pumicite in an amount of about 5% to about 100% by weight of cementitious components, 0% to about 24% of Portland cement by weight of cementitious components, and water; and allowing the plugging composition to set and form a plug.
