  • The Rheological Properties of Cement Slurries:

    Many phenomena important to oilwell cementing-e.g., gel-strength development and subsequent pressure loss in cement columns (which can allow annular fluid flow with consequently poor zone isolation) -are manifestations of the cement's viscoelastic properties. Only a small number of studies of the viscoelastic properties of cement appear in the literature. They have used a small-amplitude ...
