摘要： Embodiments can provide a method for allocating production for an oil or gas well, comprising: receiving input data comprising well test data, completion/recompletion data, and lease production data; detecting, through an outlier detection analysis, one or more outlying data points in the well test data; detecting, through a change point detection analysis of the well test data, one or more data points indicative of an intervention; generating a decline curve for each period in between the one or more data points indicative of an intervention and disregarding the one or more outlying data points; determining the production of a well for a predetermined period of time by integrating the decline curve over the predetermined period of time; and calculating the allocated production for the well by multiplying the ratio of the production of the well to the sum of the production for all wells in the lease by a production per lease value.
