Dead oil viscosity at atmospheric pressure: p = 1 atm and initial formation temperature:
| (1) | \mu_{od} = \mu_o(p = 1 atm, T_i) |
where
p = 1 \ \rm atm | Fluid pressure at 1 atm |
T_i | Initial formation temperature |
Although the dead oil may be found in petroleum reservoir under substantial pressure but when it comes to 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.
