water injecting well W0 with total sandface flowrate
, supporting pressure in reservoir volume which includes the drainage volume of producer W1 and potentially other producers {W1 .. WN}.

may be maybe related to the fact that water
injection injection in W20 is shared between
and
another reservoir or with another producerother drainage areas around other producers.
