An Improved Scheme of Frequency-Dependent AVO Inversion Method and Its Application for Tight Gas Reservoirs

Figure 11

The inversion profile through well cf563 by Wilson’s scheme. The prediction by Wilson’s scheme matches the well test at location 2. But at the locations 1 and 3, the values of P-wave dispersion gradient are not high while they are good conventional and fractured gas reservoirs. The predictions by Wilson’s scheme mismatch with well tests at the two locations.
