# Deconvolution

## Definition - What does Deconvolution mean?

Deconvolution is a mathematical technique applied in the analysis of well data to monitor the well and reservoir performance and diagnose oil and gas production from the well. The technique allows transformation of the data related to pressure and flow rate of fluid into a constant fluid flow rate pressure response from any oil well which is in a state of variable fluid flow. This makes the data analysis from reservoir and the well performance much simpler compared to analyzing data of a variable fluid flow.

## Petropedia explains Deconvolution

Deconvolution ensures the transformation of variable fluid flow rate and pressure data into linear data which is much simpler when analyzing the well and reservoir performance. When the well and reservoir are operating under variable fluid flow-pressure regime, the well data poses complex mathematical equations to analyze the well performance. This results in large wait times for the operators so as to understand this complex data using complex mathematical equations and thus, delays their well optimization and performance decisions. Thus, a deconvolution technique is used to linearize such data from a well that presently is operating under variable flow rate of fluid as well as under variable pressure. This process tries to make this variable nature of the well parameters to be converted into linear or constant rate-pressure response which ultimately is easy to interpret and thus, well production performance can be optimized. The behavior of well using this deconvolved data can easily be analyzed using standard methods of pressure transient analysis.
