A sandface pressure response to unit-rate production in the same or remote well.
It further splits into:
| DTR | pressure response to unit-rate production in the same well |
| CTR | pressure response to unit-rate production in the remote well |
The source of UTRs are:
| Numerical pressure or flow simulations | Deconvolution of long-term PDG data records | Pressure interference Testing |
The most common use of UTRs is to assemble a Pressure Interference Matrix and perform:
| Qualitative analyses of the reservoir properties | Qualitative analysis with Unit-rate Transient Response Model (UTRM) |
