Geological Model of Channel Deposits Based on Results of Spectral Decomposition and Interactive Analysis of Seismic Data

摘要

Over the past decade, digital geological modeling based on the analysis of three-dimensional seismic data securely has become a practice of exploration and development of oil and gas fields. Range of tasks expands every year, among them are risk assessment, reserve calculation, optimization of development scenarios, etc. Accuracy of the model is largely dependent on the complexity of the geological structure, data quality, interpreter experience, and some other subjective or objective factors. Particularly acute, this problem for those of complex geological objects as channels, volumetric isolation and analysis of which in the seismic field is highly difficult task.
