Annotation: The problem of determining the parameters and type of oil and gas reservoirs according to wells test data at unsteady stage filtration using the adaptive method of deterministic pressure moments under uncertainty conditions of bottom hole pressure build up curve model at its initial section is considered. Case studies are given that solve the problem of identifying and interpreting pressure build up curve of oil and gas wells using field data.
