COMPUTER-IMPLEMENTED METHOD, A DEVICE, AND A COMPUTER-READABLE MEDIUM FOR DATA-DRIVEN MODELING OF OIL, GAS, AND WATER

摘要

A method for independently modeling a water flow rate, an oil flow rate, and a gas flow rate using data-driven computer models is disclosed. The method can include obtaining parameters of a well associated with an asset during a well test; creating the ensemble of data-driven models to model the water flow rate, the oil flow rate, and the gas flow rate based on the parameters; evaluating each model of the ensemble of models; selecting a subset of models from the ensemble of models; modeling each of the water flow rate, the oil flow rate, and the gas flow rate independently using the subset of models; reconciling each of the water flow rate, the oil flow rate, and the gas flow rate for the well with a total flow rate at the asset; and outputting the water flow rate, the oil flow rate, and the gas flow rate.

1. A computer-implemented method for autonomously and independently modeling a water flow rate, an oil flow rate, and a gas flow rate of a well associated with an asset comprising one or more wells using an ensemble of data-driven computer models, the computer-implemented method comprising:
automatically obtaining one or more parameters of the well as measured by one or more sensors at one or more of a well bore, a well head, and one or more flow lines to a separator associated with the well during a well test; using the ensemble of data-driven computer models to independently model the water flow rate, the oil flow rate, and the gas flow rate based on the one or more parameters; evaluating each data-driven computer model of the ensemble of data-driven computer models based on historic, current, or both historic and current conditions; selecting a subset of data-driven computer models from the ensemble of data-driven computer models that were evaluated to independently model the water flow rate, the oil flow rate, and the gas flow rate based on the one or more parameters; modeling each of the water flow rate, the oil flow rate, and the gas flow rate independently using the subset of data-driven computer models; and automatically reconciling each of the water flow rate, the oil flow rate, and the gas flow rate that was independently modeled for the well with a total flow rate obtained at the asset; outputting each of the water flow rate, the oil flow rate, and the gas flow rate based on the modeling and outputting the each of the water flow rate, the oil flow rate, and the gas flow rate based on the reconciling.
