INTEGRATED INSTALLATION AND WORKOVER CONTROLL SYSTEM

摘要

A subsea production system for controlling fluid flow from a well. The system includes a subsea production tree and a drilling riser engageable with the well. The tree includes electrical and hydraulic lines to communicate with equipment in the tree and downhole in the well. The system also includes a tieback tool that can be installed in the tree through the drilling riser to establish communication with the tree electrical and hydraulic lines and permit access into the well bore. The system also includes an umbilical connectable with the tieback tool and extendable inside the drilling riser to the surface. The umbilical can be used to communicate the tieback tool. The umbilical can also be used to communicate with the tree and downhole equipment through the tieback tool connection with the tree.
