Hydrodynamic studies correctness of a well equipped with a singlepacker single-pump design for Multizone selective completion

Abstract

The advance of systems of Multizone selective completion is an effective solution in the development of multilayer fields, however, there are problems with determining the correct parameters of a multilayer object. To assess the correctness of the hydrodynamic studies results of wells revealing multilayer objects, a single-pack singlepump system of Multizone selective completion is selected, which provides direct estimates of individual parameters of jointly enter formation according to well testing results. It was revealed that for multilayer objects, the most informative are hydrodynamic studies in wells using a packer. The conclusion is made about the correctness of the parameters obtained during the well testing (according to the interpretation of the Pressure Transient Analysis (PTA) and Production Analysis (PA)). According to the results of the well test interpretation (WTI), it was confirmed that this arrangement provides informative hydrodynamic studies.
