Method and system for the determination of hydrocarbon accumulations

A method for determination of hydrocarbon accumulations in a subsurface geological area, the method comprising:

• mapping data to a region of the subsurface geological area, the data comprising at least one of geological data and geophysical data;
• creating a structural framework of the subsurface geological area using the data, wherein creating the structural framework comprises estimating one of initial fold axes, an axial plane, and a direction of heterogenous shear displacement resulting from a folding phase that includes a refolding phase;
• calculating a mechanical stress resulting from compressional and tensional forces in the region of the subsurface geological area using the structural framework;
• identifying trapping mechanisms causing a formation of the hydrocarbon accumulations using the compressional and tensional forces, the structural framework, and a processor;
• estimating the formation of the hydrocarbon accumulations in the subsurface geological area using the trapping mechanisms and the structural framework;
• and
• determining a location of the hydrocarbon accumulations using the formation of the hydrocarbon accumulations and the structural framework.
