Figure : Injection and Production WBHP vs. Time (in das)

*,lanation: •

As so4n in Figure + Injection WBHP 5et increasing 4ile roduction WBHP 5et decreasing 4it time. Te ig ressure and ig 'lo4 4ater injection ums 'ill te  %ottom o' te reservoir 4it te 'iltered 4ater to us te oil to4ards te roducing 4ells. It 4or5s li5e a iston. As a result+ WBHP 4ill increase. Te rocess o' using oil to4ards te roducing 4ells ta5es 6uite some times.

•

Te movement o' oil to4ards te 4ell creates a lo4 ressure to allo4 te oil to %e  roduced to te sur'ace. #ue to tis e''ect+ te roducing WBHP is decreasing over time. Te 4ater relaces te oil 4ic as %een ta5en and 5ees te roduction rate and te ressure te same over te long term.

•

Injection WBHP 5et increasing and roduction WBHP 5et decreasing until te reac sta%ili7ation oint.

•

Te sta%ili7ation oint is te oint 4ere te injection WBHP and roduction WBHP 4ould reac %e'ore te %ecome constant trougout roduction eriod.
