The effect of carbon dioxide dissolved in water on some properties of Carboxymethyl cellulose and Polyanionic cellulose used in the oil field

Abstract

This paper investigates the impact of atmospheric carbon dioxide(CO2) on the electrical properties, viscosity, and surface tension of Carboxymethyl cellulose (CMCHV) and Polyanionic cellulose (PACLV) when dissolved in water used for oil extraction. The research reveals that as carbon dioxide concentrations increase, the conductivity, viscosity, and surface tension of these substances also increase, albeit to varying extents. The findings suggest that the presence of carbon dioxide in the atmosphere can alter the physical properties of CMCHV and PACLV when they are dissolved in water used for oil extraction in oilfields and wells. This is significant because these substances are commonly used in solid-laden and water-based drilling fluids, where high viscosity can impede the filtration rate of many water-based drilling fluids. Ideally, these substances should have low viscosity. The results of this study can be used to modify the physical properties of CMCHV and PACLV, particularly their viscosity, to mitigate the effects of carbon dioxide on their behavior
