The objective of this chapter is to provide a brief overview of the types of wellhead systems and equipment commonly found on wells drilled in today ’ s oil and gas industry. First, we discuss two broad categories of surface wellhead systems: onshore and offshore. Then, we discuss wellhead systems used in subsea and ultradeepwater applications. Saigao gruop offers different types of wellhead equipment: natural gas wellhead, oil wellhead, subsea wellhead and surface wellhead. The wellhead platform equipment is compact and conventional. Welcome to order wellhead equipment from an experienced manufacturer in China! A Wellhead is a structure that is installed at the top of a natural oil or gas well. Its main function is to ensure a safe operation and manage the flow of oil or gas from the well into the gathering-system. It is a system composed of valves, spools and assorted adapters that control the pressure of the production well. The natural gas used by consumers is composed almost entirely of methane. However, natural gas found at the wellhead, though still composed primarily of methane, is not pure. Raw natural gas comes from three types of wells: oil wells, gas wells, and condensate wells. Wellhead chokes are used to limit production rates for regulations, reduce liquid loading problems, avoid sand production problems due to high drawdown, and control flow rate to avoid water or gas coning. Two types of wellhead chokes are used: positive (fixed) chokes and adjustable chokes. Wellhead systems built for performance in HPHT, heavy oil, geothermal, and shallow water environments. Meet the challenges of high pressure and temperature with a variety of HPHT valves, hangers, and seals. Optimize fluid and pressure control for effective heavy oil recovery, including thermal recovery.

There are five basic connection types commonly used in wellhead design. – Threaded – Welded – Flanged – Studded – Clamp hub – Sliplock – Connection that is unique to coiled tubing. 54.

Most of the wellheads in the oilfields are dual completed with parallel strings. There are approximately fifteen (15) different types of wellhead structures (X'mas-   For offshore oil and gas field, drilling new wells is possible only if there is still well slot available on the wellhead platform. If all well slots have been occupied, then
