The Tubing Head is the top spool on a surface wellhead. It is typically installed over the last string of pipe suspended in the well, the production casing. These heads come in a wider range of types and sizes than any other head in a conventional wellhead system. The Seaboard conventional wellhead system high capacity bowel design allows for suspension of casing and tubing to almost any depth. Wellhead and Christmas tree is the main equipment for oil production, water injection and downhole operation.

It is installed on the casing head to seal the annular space between casing and tubing, control wellhead pressure, adjust well flow rate and transport oil to pipeline.

Use of intermediate pressure rated valves psi for weight savings. Along with the knowledgeable advice of your FMC Surface Wellhead representative, this publication is designed to help you make informed decisions in specifying the best, most cost-effective solutions for your surface wellhead applications. The ultimate function of a wellhead is to contain and control the flow of liquids, gases and solids during the drilling, completion, workover, and ongoing operation of the well.

Wellhead and christmas tree equipment shipment, purchasing, repair and remanufacture of wellhead and christmas tree equipment for use in the equipment. Annex H (normative) Design and manufacture of surface wellhead running, retrieving and testing tools, clean-out tools and wear bushings. Wellhead is a general term used to describe the pressure-containing component at the surface of an oil well that provides the interface for drilling, completion, and testing of all subsea operation phases.

HPU supply hydraulic resource to open and close SSVs including MSSV, WSSV and SCSSV. The level of complexity of each well head control panel vary,.

Technology developed in Canada over the past 25. North Sea with instrumentation valves and fittings for surface wellhead pressure monitoring applications. Perhaps the most critical aspects of these design steps is the selection of casings, casing specification, casing shoe depths, and how the well is completed. This paper reviews the casing and wellhead specification process. The subsea wellhead system ( Fig.

1) is a pressure-containing vessel that provides a means to hang off and seal off casing used in drilling the well. It provides a positive seal around the cable. The wellhead is equipped with a wellhead feed through mandrel or pack-off method. Wellheads and cable pack-offs are available in various pressure ratings and hanging load capacities.

The SS-15ES Subsea Wellhead System is specially designed for use in deep water where higher bending capacities are required between the subsea wellhead and the BOP stack. Casing hangers, seal assemblies, wear bushings and running tools for the ES system are compatible with the standard SS-Subsea Wellhead System. Our well head frac stands are height adjustable and have the ability to close around a variety of wellhead sizes. Keep your site traffi c moving and your pipes protected with our rugged drive-over pipe ramps.

Accu-Flo is a product trademark. The CES-LANDTEC ACCU-FLOW wellhead is protected by U. Firmly hold the flex hose into the valve coupling while the glue dries and sets for several minutes. Our wear bushing or nominal seat protector can be run into the wellhead and left for retrieval at a later time or can be retrieved on each bit trip.

API Specification 6A – 1. A Christmas Tree comprises a series of valves, spools, a choke, and connection.

It used for production or injection wells such as oil wells, gas wells, water injection wells, water disposal wells, etc. About Encore Wellhead Systems Encore Wellhead Systems provides engineered solutions for conventional, multi-bowl, storage wellheads, underwater recovery systems, as well as frac tree and zipper manifolds. A wellhead is the component at the surface of an oil or gas well that provides the structural and pressure-containing interface for the drilling and production equipment.
