Well Tests in Dual Completions

Authors: R.S. Khisamov, A.M. Evdokimov (Tatneft OAO), V.A. Iktisanov (TatNIPIneft)

The paper deals with hydrodynamic methods to control operation of dual well completions. Different types of dual completion installations as well as well test procedures are shown here. One-string dual installation is considered to be incapable to accurately control well flow rates and watercuts. One-string electrical submersible and sucker rod pump units with plug pig and sucker rods, differential pump units make it possible to provide control and necessary time interval for well tests with application of conventional techniques.
