Although the dead oil maybe may be found in petroleum reservoir under high substantial pressure but when it comes to visocisty the usual jargon is to call discussing oil viscosity the reservoir engineering practice is usually using term "dead oil viscosity" as reference to the live oil which has been brought to atmospheric pressure until full liberation of gaseous components.
