SYSTEM AND METHOD FOR ASSIGNING EXPLORATION RISK TO SEISMIC ATTRIBUTES

摘要

An improved method for assessing the geologic risk for hydrocarbon presence and hydrocarbon accumulation size is disclosed. In one configuration, seismic attributes are assigned to a horizontal axis and data quality to a vertical axis to form a matrix crossplot. Direct Hydrocarbon Indicators (DHI) derived seismic data are used to qualify the presence and accumulation size. A quantitative method for scaling and calibrating the DHI is illustrated that can be applied to existing petroleum basins and by analog to frontier areas.
