Problem Statement

The attenuation values obtained in the lab are usually larger than those measured in the field. To understand this inconsistency, I propose to model attenuation from rock properties and reflection seismic data, and then compare their results. A gas well is used here for providing the rock properties and seismic properties. The preliminary results show that scaling is one of the factors that lower the attenuation values obtained from the field. In the future work, by adjusting more parameters (e.g., the frequency band), checking the received energy in the seismic data, and comparing those two Q models, I will understand more of the key influencing factor on the inconsistency, which helps optimize the acquisition design and choose a suitable method of measuring Q. Those conclusions can be used in practice and help understand the reservoir characterization
