Cements and cementation in geothermal well drilling

Geothermics, 1970
Abstract The full success of cementation of a casing depends on the possibility of assuring the filling-up of the annulus space between the casing and the well by a cement resisting the specific environmental conditions. Operational techniques of cementation are described and the several technical problems arising in geothermal drilling are ...
