Inverse problem to pressure convolution, performed as a fully or semi-automated search for initial pressure for every well and Unit-rate Transient Responses (UTR) for wells and cross-well intervals in order to fit the sandface pressure response  (usually recalculated from PDG data using wellbore flow model for depth adjustment ) to total sandface flow rate variation history (usually recalculated from daily allocations based on surface well tests).


The Pressure Deconvolution techniques are usually classified into the following options which use specific mathematical apparatus and deliver different volume of information:

Single-well deconvolution (SDCV)

Multi-well deconvolution (MDCV)

Applied to a stand-alone well with no interference from other wellsApplied 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 wellsApplied to a group of wells with account of all BHP and rate history
