Abstract
A gravel pack is formed using a mixture of a solid deformable material and conventional gravel pack gravel. In the event of reservoir compaction, such a gravel pack will reduce the transmission of forces from the subterranean formation to the wellbore completion hardware, thereby significantly extending the life of a well. Deformable materials selected for mixing with conventional gravel may be elastically flexible, plastically deformable, or crushable solid materials or particles.
