A new method for identifying micro fractures and characterizing fractures of different scales

Oil and gas exploration professionals have begun to focus more on unconventional oil reserves in recent years as a result of their increased efforts. Fractures significant impact the permeability connectivity reservoirs crucial component rock mechanics hydraulics, which directly affects production gas. The identification fracture development zones or micro faults, well how adequately define fracturing model, thus become pressing issues forecast reservoirs. In this study, we decompose three-dimensional seismic data volume site order obtain single frequency that can be calculated using ant tracking technique. We do by taking advantage synchronous extrusion improvement short time Fourier transform time-frequency focusing. Coupled with advanced DFN extracted are calibrated various attributes restore morphology characteristics fractures. findings demonstrate method is capable providing not only precise outline fractures but also reflection at scales, including structure associated properties. precision applicability confirmed paper, reference for industry.
