Depressants are used in petroleum production operations to reduce pour point and viscosity of paraffinic and highly paraffinic crude oils. A new ethylene-vinyl acetate co-polymer based depressant with succinimide additive is tested. The depressant performance can be estimated based on resin-asphaltene-paraffin components ratio.
Key words: highly paraffinic crude oil, depressant, pour-point, dynamic viscosity.
