This file contains a single run named “Initial history match”, in which a simple 3 phase black-oil
model has been built and simulated. The reservoir contains three wells: one producer named
“Prod 1”, and two water injectors “Inj 1” and “Inj 2”:

Long-term monitoring bottomhole pressure gauges are available at all wells, as well as daily
measurements of the oil rate at the producer and water rates at the injectors. In the
simulation the producer target is the pressure gauge, whereas both injectors are controlled by
the water injection rates.
A closer look at the simulation result shows that, although a relatively good match has been
globally achieved, the oil production is overestimated during the first two years:
