Getting fluids from
reservoir to the
separator.
1. From reservoir to
bottom of wellbore
(drawdown)
2. From bottom of
wellbore to
wellhead
3. Across choke
4. From choke across
flowline to separator
3. The basic problem of
production
We
create
•Completion design
•Choke
•Flowline dimensions
•Separator pressure
From
the
reservoir
•Reservoir pressure
•Water cut
•Oil chemistry (PVT)
5. What happens when the
well is shut in?
Initially filled with
fluid Gas cap forms
6. What happens when the
well is shut in?
Initially filled with
fluid
And water settles
out
7. In low pressure wells, tubing
head pressure can be
deceptive
Early gas

Late gas
