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: A method of forecasting production of a well penetrating a reservoir in a subterranean formation, including: receiving a plurality of bottomhole pressures for the well; receiving a plurality of flowrates for the well; determining rate normalized pressure (RNP) data for the well over a period of time based on the plurality of bottomhole pressure and the plurality of flowrates; performing a sparse identification of nonlinear dynamics (SINDy) analysis on the RNP data to identify a relationship between flowrate and bottomhole pressure for the well, wherein the SINDy analysis is based on a plurality of physics features; providing a forecast of future production for the well based on the identified relationship between flowrate and bottomhole pressure for the well; and producing fluids from the reservoir based, at least in part, on the forecast of future production.
