Title: EXPLORATION METHOD AND SYSTEM FOR DETECTION OF HYDROCARBONS FROM THE WATER COLUMN
Abstract:
A method for detecting hydrocarbons is described. The method includes obtaining seismic data associated with a body of water in a survey region, filtering the seismic data to enhance diffraction anomaly signals (1103) with respect to horizontal or nearly horizontal signals associated with the water column, analyzing the seismic data to identify at least one noise indicator (1106, 1107, 1108, 1109, 1111) to produce a noise indicator image; and determining seepage locations (1103) by comparing the at least one noise indicator image to the filtered seismic data.
