Two new simple and explicit correlations have been proposed in the present paper to calculate the density and the viscosity of carbon dioxide under operational conditions anticipated for a carbon capture and sequestration (CCS) project - pressure = 1100 - 9000 psia (7 - 62 MPa) and temperature = 40 – 100 °C. The new correlations can predict carbon dioxide density and viscosity well matched to the high accuracy carbon dioxide property data available through the National Institute of Standards and Technology (NIST) web database [1]. Substantial improvement over existing correlations has also been achieved with the new correlations.

"My experiences in publishing a paper with Bentham Open is good. I must say that the speed of publication in The Open Petroleum Engineering Journal is very fast. It takes only two month for the pioneer reviewing process. The delay was caused by me. And what’s more, the publisher’s office is quite helpful. I guess they are dealing with thousands emails every week, but they process my request in a very short period of time."
