1. A method of generating an interference prediction for a target well, comprising: generating, by a computing system, a plurality of interference metrics for a plurality of interference events for a plurality of wells using decline curve analysis based on historical production information for each well, wherein the plurality of interference events comprises a plurality of offset well completion events, and wherein the plurality of interference metrics comprises performance data for the plurality of wells both before and after each corresponding interference event;
for each well, generating, by the computing system a graph-based representation of the well and its neighboring wells;
generating, by the computing system, a predictive model using a graph-based model, comprising:
generating a training data set comprising the plurality of interference metrics for the plurality of wells, well design, completion information, and geological information for each well, and a numerical representation of the graph-based representation of each well; and
learning, by the graph-based model, an interference value for each interference event based on the plurality of interference metrics for the plurality of wells, the well design, the completion information and the geological information for each well, and the numerical representation of the graph-based representation of each well;
receiving, by the computing system from a client device, a request to generate an interference prediction for a target interference event for a target well, the request comprising one or more metrics associated with the target well, the target interference event corresponding to completion of a target offset well; and
generating, by the computing system via the predictive model, an interference metric based on the one or more metrics associated with the target well.
