Abstract
Quantitative refracture diagnostic and fracture-injection/falloff models may be used in methods for oil and gas subsurface formation evaluation techniques. More particularly, such methods may be used to select candidate wells and well candidate layers for stimulation treatments in a subterranean formation. An example of a method for selecting well candidate layers for stimulation treatments in a subterranean formation may comprise the steps of: selecting a candidate well; selecting a reservoir layer to be tested; performing a quantitative refracture-candidate diagnostic test on the reservoir layer; determining at least one reservoir property of the reservoir layer using the quantitative refracture-candidate diagnostic test; and modeling a proposed stimulation treatment using the at least one reservoir property in a reservoir simulation model so as to predict the efficacy of the proposed stimulation treatment.
