Modeling of Paraffin Deposition During Oil Production by Cold Water Injection

A new approach to modeling paraffin wax deposition during cold water injection into petroleum reservoirs has been developed. In the model, oil is represented by two hydrocarbon components (‘‘oil’’ and ‘‘paraffin’’) that do not dissolve in water. The theory of an ideal solution of a binary mixture is...

Description
Summary:A new approach to modeling paraffin wax deposition during cold water injection into petroleum reservoirs has been developed. In the model, oil is represented by two hydrocarbon components (‘‘oil’’ and ‘‘paraffin’’) that do not dissolve in water. The theory of an ideal solution of a binary mixture is used. Closing relations for the mass, momentum, and energy conservation equations describing porosity, permeability and mass transfer, are constructed using the pore size distribution function.
