Abrégé
A method and agent to induce accelerated creep deformation of shale rock formations in the annular gap between a shale formation and non-cemented sections of a casing string have been developed. A fluid containing alkali silicate or a modified alkali silicate is added to the annular space between the shale rock formation and the casing string. The alkali silicate promotes creep deformation of the shale rock, effectively closing the annulus surrounding the casing. It has been found lithium silicate provides the strongest shale-casing bond and is the presently preferred material for closing abandoned wells.

SELF-PRESSURIZING SOLUBLE ALKALI SILICATE FOR USE IN SEALING SUBTERRANEAN SPACES
The invention provides compositions and methods for sealing subterranean spaces such as natural or induced fractures, vugs or annular spaces. The composition is composed of a base fluid consisting of a soluble alkali silicate, a gas generating additive, solids and a setting agent. The gas generating additive may be coated or uncoated. The gas generating additive may also be in the form of a slurry. In the case of coated additives, the coating may act as a retarder or an accelerator to the expansion and setting agent of the soluble alkali silica. Similarly, the choice of carrier fluid in a slurry may retard or accelerate the expansion and setting of the alkali silicate-based plug.

Use of high ratio aqueous alkali silicates in drilling fluids
An improved drilling and completion fluid can be used in subterranean drilling for oil and gas. Sodium silicate and potassium silicate-based drilling fluids are commonly used drilling fluids with the notable attributes of exceptional shale stabilization characteristics coupled with exceptional environmental performance. Environmental and wellbore stabilization characteristics are improved by using high ratio aqueous silicates wherein ratio is defined as the molar ratio of SiO2:Me2O, where Me is an alkali and is most commonly sodium or potassium (i.e. Na2O and K2O). For high ratio aqueous alkali silicates, the molar ratio of SiO2:Me2O can range from just over 4.0 to about 12Ø
Soluble silicates are commonly used to block and strengthen permeable zones in subterranean formations. These applications include conformance for oil field, grouting for the construction industry and water shut-off for mining. It was discovered that set times and set properties could be improved by using novel, high ratio alkali silicates. Ratio being defined as the mol ratio of SiO2:Me/2O, where Me is an alkali metal and is most commonly sodium or potassium (i.e. Na2O and K2O).
