Two years of laboratory and field results suggest that sand control to address fines migration challenges can be overcome with proper formation analysis and engineered treatment design, including appropriate clay stabilizers and fines-fixing agents.
Most unconsolidated sandstone formations require solids production control such as well screens, often combined with gravel packs or frac pack treatments. However, these
