Title of Invention:

Acquiring AVO information from angle gathers from Seismic while drilling using multiples.

Abstract of the Invention:

The purpose of this disclosure is to acquire gather wave trains from different angles to be able to perform AVO on multiples during an seismic while drilling application.

Description of Invention:

At every point during the seismic while drilling application the source and the receiver positions are accurately known. This makes it possible to acquire data at specific source incident angles. The receivers are also acquiring wavetrains generated by multiples. The multiples may be generated by formations either above or below the borehole. By isolating multiples (deconvolution) we can perform AVO analysis to determine if potential reservoirs exist either above or below the borehole. This information can, in certain cases, be used to navigate the borehole in the new potential reservoir.
