Experimental Investigation of PhysicoChemical Characteristics of Light Weight Colloidal Gas Aphron)CGA(

This paper presents rheology, stability and filtration loss characteristics of Colloidal Gas Aphron (CGA). Eight rheological models are applied for investigation the rheological behavior of CGA based fluids and proper model are chosen in which best described the rheological properties of CGA based Fluids. Stability analysis of CGA based fluids is examined by measuring drain rate technique. Also, Standard API filtration test were applied for investigation of the CGA based fluid loss in this study. Moreover, Rheological parameters such as fluid flow index, fluid consistency and yield point were determined. The results of the experiments show that both SDS and CTAB surfactants were improved the properties of the CGA based fluids in which SDS anionic surfactant has a better performance compared to CTAB cationic surfactant.
