Abstract: Using a graphical user interface (GUI), a user is guided to generate a logical graph that represents how real data is generated in a situation. The situation is simulated using an artificial intelligence (AI) model a number of times by having the AI model choose paths through the logical graph to generate synthetic data that is representative of the real data. The AI model may also use a reward table that the user is guided to generate via the GUI to execute the simulation, wherein the reward table incentivizes certain paths of the logical graph, and agents of the AI model are trained using the values of this reward table. This synthetic data generated via the AI model can be used for training other AI models.

The first injection stream is injected into the formation at a first time and the second injection stream is injected into the formation at a second time. The first injection stream and second injection stream contact at least some overlapping portion of the formation. Oil is recovered from the overlapping portion of the formation.
