Patent number: 11988799Abstract: A method and computing system is disclosed herein. The computing system receives, from a remote computing device, a set of production information for a plurality of plays from a region. The set of production information is directed to past production of the well. The computing system generates an input data set based on the set of production information. The input data set is generated by imputing missing production data to the production information and collapsing the data set into calendar days. The computing system fits one or more decline curves to the input data set. The computing system consolidates the one or more curves into a new data set. The computing system classifies the one or more curves by identifying a subset of wells in the new data set. The subset of wells includes a threshold amount of production information. The computing system delivers the classified results to the remote computing device.Type: GrantFiled: June 12, 2020Date of Patent: May 21, 2024Assignee: RS Energy Group Topco, Inc.Inventors: Norman Runciman, Morgan Kwan, Jiarao Huang, Jianan Qu, Amanda Mackey
