Solids-free brines are used increasingly in well completion and workover operations. One technique to minimize downhole losses of expensive, high-density brine is to spot a pill of thickened brine across the thief zone. Hydroxyethylcellulose (HEC) is the polymer used most frequently for this purpose. This report discusses the properties of HEC-thickened brines and presents guidelines for their use for completion and workover fluid-loss control.
