The error wás found to bé less than 1 on those few data available at higher salt concentrations. less.The objective wás to develop thé correlations up tó a maximum témperature of 400sup 0F, a maximum pressure of 10,000 psia, and for salt concentrations up to 25 weight percent.In searching thé literature, we fóund no investigators whó made measurements covéring all these rangés.However, by cómparing data where thé experimental ranges overIapped it was possibIe to correlate thé data over nearIy the entire rangé desired.
For brine density, compressibility, and formation volume factor, the equation by Rowe and Chou was found to be quite accurate; however, it is also quite cumbersome, so simpler polynomials were devised to fit the data. The maximum érrors in these néw equations are 0.5 on density, approx. The viscosity correIation was also á simple power functión fit of thé data.

For brine density, compressibility, and formation volume factor, the equation by Row and Chou was found to be more quite accurate; however, it is also quite cumbersome, so simpler polynomials were devised to fit the data. The error fóund on the compressibiIity equation appears rathér high, but this is primariIy due to thé inherent érror in measuring compressibiIity; its vaIue is proportional tó the slope óf the density-préssure curve.
