I wanted to know if Density Delta between Water and Oil is important parameter for separation and as temp decreases, it will reduce further, making separation difficult.

How much should be the delta between these fluids as a standard practice

water density is easy to estimate,

for oil you can estimate from  specific gravity, API gravity , molecular weight...

for separators there are many papers / books, for example "Successfully Specify Three-Phase Separators",

you may also visit the Bobby Strain's website...

The section on liquid-liquid separation design in section 7 of the GPSA Engineering Data Book is both brief and useful. The worked example shows two methods of design and the table showing how typical retention times change with temperature for hydrocarbon/water separation may be of particular interest to you.
