Abstract
Mathematical well models are developed for pure water and for water-carbon dioxide mixtures. For the slug flow regime, three correlations (Orkiszewski's, Nicklin's and modified Nicklin's) are compared. An equationof- state package for water-carbon dioxide mixtures is proposed as a function of pressure and temperature. The predicted values are compared with sixteen field cases, in which the maximum carbon dioxide content is 2.8 %.
