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

<div>Time–slice of P-wave dispersion gradient along the first set sand of T<sub>3</sub>x<sup>4</sup> member. Inversion results show that the west and the southeast of the area is the favorable zone of gas reservoirs for the high value of P-wave dispersion gradient.</div>
