Abstract
The characteristics of seismic reflection on fluid-bearing strata vary distinctly with offsets. We present a methodology to highlight fluid images via instantaneous spectral differences on multi-angle stacking gathers, and propose a workflow to implement this hydrocarbon anomalies measurement. In this paper, we applied this methodology and workflow to a 3D marine seismic data volume from JX field in the Bohai Sea, China. The results demonstrate that the hydrocarbon anomalies measured by the methodology and workflow are well consistent with the real gas production of wells. The methodology and workflow presented in this paper provide an effective and relatively fast supplement measurement for hydrocarbon identification.
