Guidelines for using HEC polymers for viscosifying solids free completion and workover brines

OSTI ID:6352875

Solids free brines are increasingly used in well completion and workover operations. One technique to minimize downhole losses of expensive, high density brine is to spot a pill of viscosified brine across the thief zone. Hydroxyethylcellulose (HEC) is the polymer most frequently used 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. 2 refs.
