Chemical sand consolidation works by pumping chemicals downhole to strengthen the formation and stop sanding. In most cases reported in the industry, chemical consolidation has been used in short production intervals (less than 100 m). Our approach was to develop a laboratory program to test various industry chemicals and to achieve a good understanding of how these can be applied. Candidate wells were matched to chemicals to identify which system or systems would fit best.
Sand Remediation: Mechanical and Chemical Options
In theory, chemical consolidation should be operationally attractive and a fairly low-cost option to reduce sanding and increase production from the problem well. However, because of negative experiences with early solvent-based resin systems, it is still often viewed as a temporary measure to extend hydrocarbon production for a period of time before recompletion or well abandonment.
