Fill up time in WATERFLOODING
A field has 1 prod well, after the BHP of well Prod has reached just above the bubble point pressure, well is shut. and Injection is started from Well Inj.
1- What Should be the pressure limit of BHP-inj? Pi or Pb
2- Effect of Injection will take time to reach production well and after that much time BHP-prod start increasing, at what value of BHP-prod the prod well should be put on production again?

For clastics reservoir:
1. Bottomhole pressure limit of injector should be the fracture pressure. You should estimate the fracture pressure of the reservoir, and ensure that the bottomhole injection pressure does not exceed the reservoir fracture pressure.
2. The minimum reservoir pressure of a reservoir (for oil), is the critical gas saturation pressure. It is estimated to be about 50psia below the bubble point pressure. Once the reservoir pressure goes above (Psat-50psia), then it is save to open up the well and produce again.
*Note: Psat = Bubble point pressure.

Here's a great class materials from W. Cobbs on waterflooding. It preety much covers the whole topic.
Hope it helps!
