The evaluation of turbidity and total suspended solids of completion fluid is a necessary operation. The completion of wells without consuming a lot of time, damaging the zone and controlling the formation pressure gave rise to the evaluation and correlation of NTU and TSS in the selected area. Selecting a properly designed, compatible fluid with evaluation and correlation of NTU and TSS in the selected area is a means of mitigating these effects of hydration of formation clays, wettability changes, pressure differential, water blocking, emulsion blocking, paraffinic or asphaltic plugging, formation of precipitates, and migration/dispersion of formation clays and prolonged displacement period. In this work the borehole water and seawater samples collected from selected operations areas in Southern Nigeria at specific depth were used. Mix borehole water and seawater samples were collected from selected operations areas in Southern Nigeria at specific depth and laboratory analysis/measurements were carried out. The densities of water and brine samples were measured. The density of Owaza water (8.31ppg) and CaCl brine sample was the highest with 10.91ppg specific gravity and Obagi water (8.30ppg) and KCl brine was lowest with 9.44ppg. The brine NTU and TSS data extracted from was used to develop a correlation of R² = 0.765 which is good for the determination of NTU of brine with its TSS. Also, software has been developed for determining each variable that is needed.
