A method is described for identifying source rocks in a subsurface volume of interest. The method may include generating a trend-normalized reflectivity seismic attribute and calculating the location, thickness, organic richness and thermal maturity of the potential source rocks based on seismic data. The method may be executed by a computer system.

System and method for mapping hydrocarbon source rock using seismic attributes

A method is described for generating an improved digital image for a subsurface volume of interest that allows analysis of the depositional settings of rock facies in a subsurface volume of interest. The method may include identifying at least three different rock facies in the well log data; estimating a compaction trend for each of the at least three rock facies identified in the well log data to create at least three compaction trends; transforming the velocity model to produce a trend-match volume using the at least three compaction trends; and superimposing the trend-match volume and the seismic image to generate a digital image containing information regarding both structural features and stratigraphic features of the subsurface volume of interest. The method may be executed by a computer system.
