Abstract
A method for sealing an annular space between a bore hole and a casing includes the steps of: providing a fluid sealing system comprising a particulate material and a bonding agent; positioning the fluid sealing system in the annular space whereby the particulate material adheres to walls of the bore hole and the casing; and curing the fluid sealing system so as to form a solid seal in the annular space.
