A cross-well type of Unit-rate Transient Response (UTR): Sandface pressure response drop in well "m" to unit-rate () production from the well "k":
p_{u,mk}(t) = p_{{\rm wf}, m}(0) - p_{{\rm wf}, mk}(t)|_{q_m =1} > 0 |
It's a virtual analogue of a unit-rate step-response pressure interference test to the shut-in well "k" from the constant unit-rate production from the well "m"
