Iterative and repeatable workflow for comprehensive data and processes integration for petroleum exploration and production assessments

A non-transitory, computer-readable medium storing one or more instructions executable by a computer to:

• initialize a workflow of a plurality of model simulation processes, wherein the plurality of model simulation processes comprise, in order:
• structural modeling, stratigraphic modeling, petroleum system modeling, fluid flow modeling, petro-elastic modeling, and forward seismic modeling, wherein the model simulation process are associated with a plurality of workflow parameters, wherein each model simulation process is associated with a respective local objective function, and wherein the respective local objective functions combine to form a global objective function for the workflow;
• starting with a first model simulation process and for each of the plurality of model simulation processes in order:
• prepare input data for the model simulation process input data for the model simulation process, wherein the prepared input data comprises at least one of raw measured data or an output of a previous model simulation process in the workflow;
• execute the model simulation process using the prepared input data;
• compute a mismatch value by using the respective local function to compare an output of the model simulation process to the raw measured data for the model simulation process;
• update the global objective function with the computed mismatch;
• and
• add the computed mismatch to the global objective function;
• send the prepared input and the output of the model simulation process to a subsequent model simulation process in the workflow;
