( also called unit-rate self-response )
In single-well deconvolution:
Sandface pressure response drop

...
to the constant unit-rate production

In multi-well deconvolution applications the above definition is usually abbreviated as:

p_u(t) = p_{\rm wf}(0) - p_{\rm wf}(t)|_{q = 1} >0, \quad p_{u}(0) = 0

In multi-well deconvolution:
Sandface pressure response drop in Sandface pressure response
in well "m" to the constant unit-rate production
from the same well "m"

p_{u,mm}(t) = p_{{\rm wf}, mm}(0) -p_{{\rm wf}, mm}(t)|_{q_m = 1} >0, \quad p_{u,mk}(0) = 0
