COMBINED WIDE AND NARROW AZIMUTH SEISMIC DATA ACQUISITION SYSTEM AND METHOD

Title:

COMBINED WIDE AND NARROW AZIMUTH SEISMIC DATA ACQUISITION SYSTEM AND METHOD

Document Type and Number:

WIPO Patent Application WO/2014/131854

Kind Code:

A3

Abstract:

There is a method for acquiring seismic data over a survey area. The method includes deploying streamer and source vessels to acquire seismic data along a survey line; performing one pass with the streamer and source vessels along the survey line for collecting wide azimuth (WAZ) data; and performing another pass with the streamer and source vessels along the survey line for collecting narrow azimuth (NAZ) data.
