METHODS AND COMPOSITIONS FOR CONSOLIDATING PROPPANT IN SUBTERRANEAN FRACTURES.

摘要

Improved methods and compositions for consolidating proppant in subterrane an fractures are provided. In accordance with a method of the invention, proppa nt particles coated with a furfuryl alcohol resin composition are mixed with a gelled liquid fracturing fluid and the fracturing fluid is pumped into a subterranean zone. The fracturing fluid forms one or more fractures in the subterranean zone and deposits the proppant particles coated with the resin composition therein. Thereafter, the hardenable resin composition on the proppant particles is allowed to harden by heat and consolidate the proppant particle s into chemical and thermal degradation resistant permeable packs.
