significantly. This uplift occurred because
the lower injection rate yielded a greater
reduction in liquid density. Slower injection
also meant lower costs.

Barrel Water/Day
Gas lift not working. Liquid
production fell below the
predicted decline.
By enabling extra production and lower
costs from optimizing injection rates, gas
lift surveys can pay for themselves tenfold
and continue to produce revenue long
after they are performed. Over time, a
comprehensive gas lift survey program
can reduce well intervention costs by
millions of dollars.
❒
Ran gas lift pressure and
temperature survey with
valve performance.
Liquid rate improved
after incorporating
recommendation from
P/T survey (i.e. lower
injection).
