System and method for analysis of depositional settings of subsurface reservoirs

A computer system configured to generate an improved digital image for a subsurface volume of interest, comprising:

• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions that when executed by the one or more processors cause the device to:
• a. receive a seismic image representative of the subsurface volume of interest and a velocity model;
• b. receive well log data representative of wells drilled in an analogous region to that of the subsurface volume of interest;
• c. identify at least three different rock facies in the well log data;
• d. estimate 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;
• e. transform the velocity model to produce a trend-match volume using the at least three compaction trends;
• and
• f. superimpose 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.
