Abstract: The present invention relates to the use of a composition for stabilizing a geological formation in oil fields, gas fields, water pumping fields, mining or tunnel constructions. The composition has a hardening temperature in the range from about 40° C. to about 120° C. and can therefore be used to stabilize a geological formation in oil fields, gas fields, water pumping fields as well as in mining or tunnel constructions.

Abstract: The invention relates to a process for the curing of latently reactive, heat-curable compositions which do not harden at room temperature. The composition includes a polymer obtainable via reaction of certain compounds having two aldehyde groups with polyacrylate compounds having two or more acrylate groups, and also a compound which bears at least two thiol groups.

Abstract: A pumpable shelf-stable suspension of fibers in an organic phase comprising 1.0-60 wt % of fibers and 0.01-10 wt % of a disubstituted urea is proposed as well as a method using the disubstituted urea to suspend fibers in an organic phase.
