Abstract: A method of detecting one or more well interference events at a well penetrating a reservoir in a subterranean formation is provided. The method includes: receiving wellhead pressure and flowrates of oil, gas, and water for the well during production; calculating a bottom hole pressure (BHP) of the well based on the wellhead pressure and flowrate of oil, gas, and water; calculating an average reservoir pressure based at least on the BHP; determining a productivity index (PI) for the well for a plurality of time steps based at least on the average reservoir pressure; determining a dataset of PI values and corresponding cumulative fluid production values from the well; analyzing the dataset to determine one or more breakpoints in a relationship between PI and cumulative fluid production representing one or more well interference events; and producing fluids from the reservoir based at least on the one or more breakpoints.

Abstract: An apparatus for estimating a gas-oil ratio for a well in an unconventional reservoir comprises a processor associated with a control system. The processor is configured to determine a bottomhole pressure for the well. The processor is further configured to determine one or more pressure, volume, and temperature (PVT) properties associated with fluid flow and to determine transient well performance. The processor is further configured to determine a Productivity Index (PI) for the well for a plurality of time steps and to determine an inflection point. The processor is further configured to estimate the gas-oil ratio of the well after the inflection point based on the determined transient well performance and to perform the fluid production rate forecast based on the determined PI. The processor is further configured to apply the fluid production rate forecast to the estimated gas-oil ratio to determine an instantaneous gas-oil ratio.
