DOLOMITE MAPPING USING MULTISCALE FRACTURE CHARACTERIZATION

摘要

Methods for dolomite mapping using multiscale fracture characterization include using a computer system to receive seismic data for a geographical area. The computer system identifies one or more macroscale fractures located within the geographical area based on a three-dimensional (3D) visualization of the seismic data. The computer system identifies one or more mesoscale fractures located within the geographical area based on a curvature map generated from the seismic data. The computer system identifies one or more microscale fractures located within the geographical area based on an amount of chaotic seismic reflections indicated by the seismic data. The computer system identifies a dolomite distribution of the geographical area based on the one or more macroscale fractures, the one or more mesoscale fractures, and the one or more microscale fractures. A display device of the computer system generates a graphical representation of the dolomite distribution.
