# Pre-stack deconvolution revisited

## TL;DR

This paper revisits pre-stack deconvolution in seismic data, analyzing how finite offset effects influence the convolution model and the interpretation of reflectivity series.

## Contribution

It investigates the impact of finite offset on pre-stack deconvolution, addressing a previously overlooked aspect in seismic data processing.

## Key findings

- Finite offset affects the convolution model in seismic data.
- Neglected effects can lead to misinterpretation of reflectivity.
- The study clarifies the role of incident ray direction in seismic deconvolution.

## Abstract

While in the case of zero offset data with horizontal beds, it is clear that the recorded trace is a convolution of the wavelet and reflectivity series, the situation in the case of finite offset is a bit more complex as the direction of the incident ray is not vertical, the natural direction in which the reflectivity series is measured.We examine the consequences of this hitherto neglected fact.
