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.
Claims18
A method for sealing an annular space between a bore hole and a casing, comprising the steps of:
- providing a fluid sealing system comprising a particulate material and a bonding agent comprising an alcohol-acid suspension of nanoparticles;
- positioning said fluid sealing system in said annular space whereby said particulate material adheres to walls of said bore hole and said casing;
- and
- curing said fluid sealing system so as to form a solid seal in said annular space.
A composition for sealing bore holes, comprising a fluid sealing system containing a particulate material ad a bonding agent comprising an alcohol-acid suspension of nanoparticles, wherein said bonding agent is activatable to bond particles of said particulate material and form a solid seal.
