Data were forwardly and inversely inverted in 3D using STRATA Seismic Inversion Software (Hampson Russell Software & Services Limited, USA). Often it can enhance features such as bed resolution, minor faulting, fracture zones and discontinuities due to channels and possibly the presence of hydrocarbons. absolute impedance inversion scheme was mainly used to estimate acoustic impedance volume from the Simian field seismic cube. It honours well control giving more accuracy than recursive inversion or integration for example, and does not require an explicit wavelet.Ĭoloured Inversion enhances the seismic signal and aids the auto-picker. We start by formulating the two approaches in a theoretically comparable manner. One is colored inversion (CI), which requires well-log information, and the other is linear inversion (LI), which requires knowledge of the seismic source wavelet. A matching filter is designed and the seismic traces are processed to match the coloration of the acoustic log data. We have revisited and compared two alternative methods to transform stacked seismic data into RAI. Methodology The 3D seismic cube is inputted in the Hampson-Russell. Seismic colored inversion is relatively faster than traditional inversion methods (Lancaster and Whitcombe 2000 Ansari 2014). Coloured Inversion is a fast and lightweight tool that enables interpreters to quickly generate a relative acoustic impedance data type from the reflection seismic data for the purpose of more accurate, more confident seismic interpretation.Ĭoloured inversion is a robust method for “quick-look” inversion, which has been shown to produce results comparable with the more involved and computationally intensive “sparse-spike” method. 2015 MODEL-BASED INVERSION IN NORTH SEA F3-BLOCK DUTCH SECTOR By Hassan Hussien. Colored inversion is a post stack seismic inversion technique which transforms seismic data into acoustic impedance.
