Oil and gas well wellhead equipment can be divided into three types: flowing well wellhead equipment, pumping well wellhead equipment and gas well wellhead equipment.

The same principle of well tubing suspension goes for the three kinds of wellhead equipment. Today, oilfields generally adopt the jacking valve suspension method, that is, a jacking valve is installed on the casing four-way, and there is a tapered channel in the jacking valve. The tubing hanger is also a cone.

With a sealing ring, the tubing suspension sits firmly in the seat of the jacking valve under the pull of the weight of the entire wellbore tubing. The function of the jack wire is to prevent the tubing string from being pushed out when the pressure in the well is too high.
During workover operations, after killing the well, remove the wellhead equipment above the casing spool firstly, then loosen the jack wire and take out the tubing before starting to construct according to the design. After the construction is completed, the tubing is seated in the tubing suspension with the jacking valve tightened, and the wellhead device is installed. So far, the construction is completed.
It’s not just a wellhead and tree—that’s only the reliable foundation of our life-of-well SLB intelligent surface production system. We’ve introduced new levels of production and injection functionality by bringing together electrification, digitalization, and sensing with our wellhead systems for any application and any environment worldwide. Whether your project is a critical conventional or unconventional oil and gas application; vapor, liquid, or dry geothermal operation; or permanent carbon capture and sequestration (CCS) installation, we’ve seamlessly integrated all system components with edge computing to keep you informed, enable precise remote control, and provide data-backed insight for continuous optimization across the production lifespan of your well.
