Technical Abstract

Ultra-low frequency phase assessment for broadband data

Back to Technical Content
Reliable low frequency content and phase alignment are critical for broadband seismic inversion and the prediction of reservoir properties. However, currently there is a lack of tools for ultra-low frequency (less than 5 Hz) quality and phase assessment. A focusing metric in the impedance domain is proposed to assess the ultra-low frequency phase alignment. The method has been applied on a real broadband dataset for the assessment of the residual phase correction process and the conclusion is validated by using well information.
