Abstract

AVO attributes are determined from seismic survey wave data and a relationship derived between the AVO attributes and specific rock property contrast including inter-face (cap/reservoir), inter-location (A/B), or inter-time (T1/T2). At least two amplitude variation as a function of offset ('AVO') attributes are determined for at least one set of seismic traces. Linearized equations providing curve fit parameters and basic functions are disclosed for determining the AVO attributes. Incident compression wave to reflected compression wave (P-P), incident compression wave to reflected shear wave (P-S), isotropic horizontal reflected wave (S-SH), isotropic vertical reflected wave (S-SV) and joint P-P and P-S AVO attributes are determined and a relationship derived to directly relate the AVO attributes to specific rock property contrasts. The obtained rock property contrasts are used to detect hydrocarbons in the geologic formation at the location of interest.
