Multi-z horizon visualization from seismic data

A system comprising:

• a processor;
• and
• a memory coupled to the processor and storing processor-readable instructions, which, when executed by the processor, cause the processor to perform a plurality of functions, including functions to:
• display a two-dimensional (2D) representation of seismic data via a graphical user interface (GUI) of an application executable at a computing device of a user;
• receive input from the user for interpreting a multi-Z horizon within a portion of the displayed 2D representation of the seismic data via the GUI;
• track the user's input relative to the portion of the 2D representation of the seismic data displayed within the GUI, as the input is received from the user;
• determine each of a plurality of surfaces for the multi-Z horizon within the portion of the 2D representation of the seismic data, based on the tracking;
• identify at least one intersection point between the plurality of surfaces of the multi-Z horizon within the portion of the 2D representation of the seismic data;
• determine a depth position for each surface relative to the other plurality of surfaces of the multi-Z horizon;
• and
• dynamically update the 2D representation of the seismic data within the GUI to include a plurality of visual indications for the plurality of surfaces and the at least one intersection point, based on the depth position determined for each surface, the plurality of visual indications using different visualization styles to represent the plurality of surfaces and the at least one intersection point between the plurality of surfaces.
