ABSTRACT:
A method for minimizing formation damage during gravel packing operations in a loosely consolidated hydrocarbonaceous fluid producing formation penetrated by at least one well. Solidifiable chemical blocking agents are used to keep intrusive fluids, e.g. kill fluids, from the hydrocarbonaceous fluid producing interval of said formation during said gravel packing operation.
