METHOD OF GROUTING POROUS GAS - AND PETROLEUM - BEARING FORMATIONS

A method of grouting porous gas - and petroleum - bearing formations with a cementitious material (40) comprising ultrafine ground slag is useful for primary and remedial cementing of a wellbore (37). A composition is provided which comprises water, a dispersant, slag and an accelerator to activate...
