Abstract

Method and apparatus for remotely controlling subsea template production systems having a plurality of satellite wells and a plurality of subsea trees on the well templates uses a significantly reduced number of electrical and hydraulic lines between a surface control unit and a riser base on the seafloor. An electrohydraulic control module on the riser base receives electrical control signals and provides hydraulic output signals to operate the riser base. Electrohydraulic control modules on the templates receive electrical control signals and provide hydraulic output signals to control operation of the trees on the templates. The satellite wells are each controlled by a single hydraulic signal line connected between the surface control unit and a matrix switching control module at the satellite well. All of the electrohydraulic modules are replaceable using surface operated running tools.
