Method and system for predicting formation top depths

A system, comprising:

• a logging system coupled to a plurality of logging tools;
• a drilling system coupled to the logging system;
• and
• a reservoir simulator comprising a computer processor, wherein the reservoir simulator is coupled to the logging system and the drilling system, the reservoir simulator comprising functionality for:
• obtaining seismic data regarding a geological region of interest;
• obtaining well log data from a wellbore within the geological region of interest;
• and
• determining, by the computer processor, a formation top depth using the seismic data, the well log data, a stratigraphic column, and a machine-learning model,
• wherein the stratigraphic column describes an order of a plurality of formations within the geological region of interest, and
• wherein the machine-learning model assigns one or more features among the seismic data and the well log data to a formation among the plurality of formations in the stratigraphic column to determine the formation top depth.

A non-transitory computer readable medium storing instructions executable by a computer processor, the instructions comprising functionality for:

• obtaining seismic data regarding a geological region of interest;
• obtaining well log data from a wellbore within the geological region of interest;
• and
• determining a formation top depth using the seismic data, the well log data, a stratigraphic column, and a machine-learning model,
• wherein the stratigraphic column describes an order of a plurality of formations within the geological region of interest, and
• wherein the machine-learning model assigns one or more features among the seismic data and the well log data to a formation among the plurality of formations in the stratigraphic column to determine the formation top depth.
