A study performed by Marbun et al. [1] claimed that “A new methodology to predict fracture
pressure from former calculations, MattheweKelly and Eaton are proposed.” Also, Marbun et al.'s
paper stated that “A new value of Poisson's and a stress ratio of the formation were generated and
the accuracy of fracture gradient was improved.” We found those all statements are incorrect and
some misleading concepts are revealed. An attempt to expose the method of fracture gradient
determination from industry practice also appears to solidify that our arguments are acceptable to
against improper Marbun et al.'s claims.
