Packers-Subsurface Safety Valves

Packers

Packers systems are among the most important tools in the tubing string. The types of packer systems vary greatly. Often, they're designed or configured to meet specific wellbore or reservoir conditions, such as single-packer or tandem-packer configurations, single-tubing or dual-tubing strings, and the full range of pressure and temperature applications.

The basic requirement of packers systems and associated tools relates to flow from or injection into the formation to the tubing string or production conduit. The packer must enable efficient flow and must not restrict normal production or injection flow.

Subsurface Safety Valves

Work on subsea wells is a costly and hazardous process. Crucial to efficiency and safety are the successful installation, dependable operation, and long-term reliability of subsurface safety and injection valves.

Safety valves, an integral part of well completions, protect offshore and land production installations. Schlumberger surface-controlled subsurface safety valves use the innovative rod piston hydraulicactuation system developed by Schlumberger. All series contain a rugged, metal-to-metal Inconel flapper closure mechanism plus secondary soft seal. Schlumberger offers six main safety valve styles, ranging from basic to the most high-tech design available in the industry.
