Systems and methods for forecasting well productivity

A system comprising:

• at least one processor coupled with at least one computer-readable storage medium having stored therein instructions which, when executed by the at least one processor, causes the system to:
• obtain an input sequence of input data features associated with a well for at least one time stamp during a period of time, the input data features associated with the well for the at least one particular time stamp during the period of time comprising well production rates for the well and well operation constraints for the well;
• divide the input data features into a training data subset, a validation data subset, and a test data subset;
• build a well production model for the well using machine learning based on the training data subset, the validation data subset, and the test data subset;
• and
• generate a forecast for the well for a future period of time using the well production model, the forecast comprising a future well production rate for the well including at least one of an oil rate, a gas rate, and a water rate.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• obtaining an input sequence of input data features associated with a well for at least one time stamp during a period of time, the input data features associated with the well for the at least one particular time stamp during the period of time comprising well production rates for the well and well operation constraints for the well;
• dividing the input data features into a training data subset, a validation data subset, and a test data subset;
• building a well production model for the well using machine learning based on the training data subset, the validation data subset, and the test data subset;
• and
• generating a forecast for the well for a future period of time using the well production model, the forecast comprising a future well production rate for the well including at least one of an oil rate, a gas rate, and a water rate.
