A machine learning model is trained to facilitate determination of transient inflow performance relationship for a reservoir. A type reservoir model for the reservoir is developed and run multiple times with different input parameters to generate multiple production simulations for the reservoir. The input parameters and the results of the multiple production simulations for the reservoir are used to train a machine learning model. The trained machine learning model facilitates determination of transient inflow performance relationship for the reservoir by providing time-series prediction of average pressure, production rate, and absolute open flow of the reservoir.

IN-SITU DOWNHOLE SEPARATION FOR OIL AND GAS RESERVOIRS
A method of separating gas and liquid within a well bore includes positioning a production tube within the well bore such that the production tube extends from a subterranean reservoir, traverses a gas cap, and out of the production well bore. An in-situ downhole separation system is configured such that during production, produced fluid enters a separation zone formed in the well bore. The fluid flows within the separation zone in a direction from the reservoir and toward the gas cap, and at least some gas of the produced fluid separates from liquid of the produced fluid as separated gas that is reinjected into the gas cap. The remaining fluid is withdrawn through the production tube. Additional amounts of the gas may be separated from the liquid using a gas liquid separation device and/or a pump mechanism of the in-situ downhole separation system.
