The design of highly efficient field development systems, their control and management require reliable information about the reservoir properties and structure of productive deposits. Among the most common and informative methods of obtaining information is well testing with the help of pressure build-up curves (PBU). The latter make it possible to study the structure and parameters of the farfield at a considerable distance from the well (tens and hundreds of meters), which allows to make informed decisions in the process of field development. Therefore, the use of PBU test interpretation methods in order to obtain maximum information is extremely relevant for hydrocarbon recovery processes. Well testing under nonequilibrium filtration conditions is one of the powerful tools for assessing the reservoir parameters, the structure of the farfield and assessing the well potential. The use of modern software tools for well test results interpretation allows to obtain much more information from the classical results, to clarify the structure of the field and the parameters of productive reservoirs. The aim of this work is to generalize the world experience of the farfield influence on the character of PBU and its derivative during well testing under nonequilibrium filtration conditions. The study has been conducted using the KAPPA Saphir software package, licensed for use by IFNTUOG for educational purposes. The above methods of PBU interpretation can be used to determine the farfield parameters and structure. On the basis of those one can make effective decisions on field development managing and during 3D geological models creation.
