An Effective Method for Inversion of Elastic Impedance for Shallow Sediments and Its Application to Gas Hydrate-Bearing Sediments
Myung W. Lee
2006, Scientific Investigations Report 2006-5297
Elastic properties of gas hydrate-bearing sediments (GHBS) are important for identifying and quantifying gas hydrate as well as discriminating the effects of free gas on velocity from that due to overpressure. Elastic properties of GHBS sediments can be estimated from elastic inversion using the elastic impedance. The accuracy of elastic...
