During the extraction process, and possibly later, the engineer may decide to control the
derivative smoothing, apply a logarithmic filter, and in the case of a shut-in, control the last
flowing pressure.

Deconvolution
The new deconvolution method developed in the last few years was presented in a previous
section. Extraction of the deconvolution may occur right after the extraction of the individual
shut-ins, or much later after the interpretation of the individual shut-ins.
