METHOD OF CONSOLIDATING PARTS OF PERMEABLE UNDERGROUND FORMATION USING DIMETHYLAMINOMETHYLPHENOL

摘要

To consolidate subsurface formation parts around a well or borehole, a treating solution including an epoxy compound and a hardening agent is injected thereinto, this solution optionally being preceded by a pre-flush liquid. The solution and the pre-flush liquid displace mobile fluids in the formation, but leave water adhering to the wall of the pore space thereof. Dimethylaminomethylphenol is dissolved in the solution and/or in the pre-flush liquid.
