“…The Bingham plastic model ͑i.e., F 1 ϰ ‫ץ‬V / ‫ץ‬y͒ appears to be well suited to some sediment-laden flows with large concentrations of fine particles ͑e.g., Wan and Wang 1994;Julien 1995͒. A more advanced rheological model is the Herschel-Bulkley fluid model for which F 1 ϰ ͑‫ץ‬V / ‫ץ‬y͒ m , where 0 Ͻ m ഛ 1 ͑e.g., Huang and Garcia 1998;Wilson and Burgess 1998͒. Various models have been proposed to describe the behavior of thixotropic fluids ͑e.g., Mewis 1979;Usui 1995;Toorman 1997͒. Most have a similar structure consisting of an equation of the form ͑2͒ now with parameters depending upon some structure parameter͑s͒, associated with some kinetic equation͑s͒ giving the time evolution of the͑se͒ structure parameter͑s͒ as function͑s͒ of time and shear rate.…”

“…As propriedades reológicas dos fluidos de perfuração estão diretamente relacionadas ao sucesso da conclusão de um poço por perfuração e ao custo do projeto [8,9]. O termo tixotropia veio originalmente da ciência dos coloides e mais recentemente foi melhor definido [10][11][12]. Embora esse termo tenha passado por mudanças na sua definição de acordo com a área de interesse [13], uma definição aceita de tixotropia envolve a diminuição gradual da viscosidade sob tensão de cisalhamento seguido por uma recuperação gradual da estrutura quando a tensão é removida [14,15].…”

“…Existe uma forte relação entre a reologia e estabilidade coloidal (MEWIS, 1979). Os efeitos coloidais determinam as forças inter partículas durante a deformação e consequentemente à variação estrutural e as características reológicas (MEWIS; SPAULL, 1976).…”
