Risks resulting from using rules-of-thumb when cementing oil wells; Riscos decorrentes do uso de chavoes nas cimentacoes de pocos de petroleo

Abstract

In the oil industry the two most popular rules-of-thumb related to interpreting the thickening time tests are: 'On reaching 50 Uc (consistency units) the cement slurries are no longer pumpable' and 'Time spent on mixing and displacing the slurries should not exceed 60% of the thickening time'. To check these rules more then 200 experimental tests were carried out which show that depending on the additives used, the consistometry curves may require individual interpretation and slurries with different composition have great changes of showing different apparent viscosities even when having the same consistency.
