Stationary flow with reservoir and fluid staying at quasistatic equilibrium and fluid pressure and temperature are not changing in time:
p(t, {\bf r}) = p({\bf r}) |
T(t, {\bf r}) = T({\bf r}) |
Well production or injection resulting in steady state flow is characterised by:
| constant flowrate | ||
| constant formation pressure | ||
| constant bottomhole pressure | ||
| constant productivity index |
