Inverse problem to pressure convolution trying to find unit-rate transient responses which relate recorded pressure variation to flowrate variation history.
It is The Pressure Deconvolution techniques are usually classified into the following options which use specific mathematical apparatus and deliver different volume of information:
| Applied to a stand-alone well with no interference from other wells | Applied to a group of interfering wells | |
| Radial Deconvolution (RDCV) | Cross-well Deconvolution (XDCV) | |
| Applied to a well with BHP readings and no account of the BHP readings in offset wells | Applied to a group of wells with account of all BHP and rate history | |
