Abstract
A composition for consolidating a carbonate rock formation includes ground calcium carbonate (GCC) and a solvent. A method of consolidating a carbonate rock formation includes providing a consolidant composition comprising ground calcium carbonate (GCC) and a solvent, applying the consolidant composition to a rock formation, and allowing the GCC to precipitate onto the rock formation.
Claims20
A composition for consolidating a carbonate rock formation comprising:
- ground calcium carbonate (GCC), wherein the ground calcium carbonate has an average particle size of from 0.2 μm to 30 μm;
- and
- 1,4-butanediol;
- wherein the composition comprises from 10 g to 20 g of the GCC per 100 ml of the 1,4-butanediol,
- wherein the composition is substantially free of silicates;
- the composition is substantially free of Ca(OH) 2 nanoparticles;
- and
- the composition is free of acid.
