Modified Extended Elastic Impedance and Simultaneous Avo Inversion for Estimating Reservoar Lateral Lithologic and Pore-Fluid Heterogeneities from Seismic Data

(Universitas Indonesia, 2006)

Lateral litology and saturation heterogeneities is the key for reservoir

characterization. Amplitude versus offset (AVO), which is based on the

reflection response change caused by the change of incident angle, provides

the relationship between reservoir parameter, petrophysical parameter and

elastic constant.

Conventional AVO analysis and modeling by iteratively picking on the

reflection event sometimes could be difficult due to practicalities of picking,

resolution problem, and thin layer effects. Lithofacies identification based on

seismic impedance inversion can alleviate this difficulties. Impedance

inversion also relatively free from the horizon interpretation problem, which

can be subjective in heterogeneities reservoir.

In this study, we modify the Extended elastic Impedance (EEI) to predict

lateral lithologic and saturation hetereogities from seismic data. In order to

validate the developed method we apply Simultaneous AVO inversion. The

modified extended elastic impedance method is a least square weight

combination of intercept and gradient to produce lateral and vertical elastic

parameter or log analysis of interest. The method provides more reliable and

stable result compare to the original extended elastic impedance. In addition,

the method produces any type of elastic parameter without explicit relation

function.
