... of attenuation rate measurements, which responds accordingly in higher bonding environments. The two methods are used in a hybrid approach providing a full range quantitative bond index (QBI) introduced by Izuhara et al. (2017) . In order to conform with local requirements related to well integrity...

The amplitude and the attenuation of the returned wave can be correlated with Bond Index (BI), due to the difference in acoustic impedance between casing and cement. Over years, different wireline technologies have been...

.... This data processing involves two steps: 1) estimate the amount of seismic attenuation that a gas-bearing layer creates, and 2) fit a wave attenuation model to the observed attenuation. We accomplish the first step using a wavelet- based spectral ratio approach, and find the seismic quality factor...

... Abstract Seismic waves propagating in the earth are affected by attenuation. Attenuation is the progressive loss of energy with each cycle of the wave. The resulting seismic data has a frequency and time dependent loss of amplitude and a phase rotation of the wavelet. Traditionally attenuation...
