Specific data processing and interpretation workflow of production/injection history and permanent downhole gauges data based on unit-rate transient responses, usually acquired from multiwell deconvolution.
It includes the following stages:
| PDG data filtering |
| Multiwell deconvolution |
| Formation pressure history reconstruction (from deconvolution) and NFA Pe forecast (from convolution) |
| Productivity index history reconstruction (from deconvolution and NFA PI forecast (from convolution) |
| Interference history reconstruction (from deconvolution) and NFA pressure interference forecast (from convolution) |
| UTR diffusion modelling |
