Abstract:
Methods of forming gravel packs while reducing fluid loss to the surrounding subterranean formation. The methods involve suspending gravel that has been coated with a tackifying agent and degradable fines into a low viscosity carrier fluid and then placing that suspension into a subterranean formation so as to form a gravel pack wherein, as the gravel pack is placed, the degradable fines to de-adhere from the gravel and to fill at least a portion of the pore spaces within the gravel pack so as to reducing fluid loss through the gravel pack.
