Patent
·
OSTI ID:7048659
A high stability, nondamaging spacer fluid is provided containing readily available weighting agents such as calcium carbonate and iron carbonate dispersed in water using a polymer viscosifier, a salt inhibitor, a primary sulfonated dispersant and a secondary fatty acid amide dispersion. Conventional high density weighting agents can also be used. The spacer fluid is stable over a temperature range of about 32-300/sup 0/F for extended periods.
