API – 6A – 20th Edition

In general well heads are five nominal ratings of wellheads: Weld NDE — General The essential welding variables and equipment shall be monitored; welding activities shall be audited. Retrieved from ” https: Wikimedia Edifion has media related to Wellheads. Offshore, where a wellhead is located on the production platform it is called a surface wellheadand if located beneath the water then it is referred to as a subsea wellhead or mudline wellhead.

All provided information is only intended to be informative about the basic required NDE testing and does not include any Tensile, Impact, Dimensional, Traceability or Chemical Analysis testing that may be required per API 6A, 20 th All provided information is only intended to simplify the NDE requirements of API 6A, 20 th The code should be used when requesting or preforming inspections. If the pressure is not contained during drilling operations by the column of drilling fluidcasings, wellhead, and BOP, a well blowout could occur.

PSL 4 — Required Non-Destructive Testing Material NDE — Volumetric Examination As far as practical, the entire volume of each part shall be volumetrically inspected radiograph or ultrasonic after heat treatment for mechanical properties and prior edktion machining operations that limit effective interpretation of the results of the examination. They are used in conjunction with ring type seal gaskets.

When the well has been drilled, it is completed to provide an interface with the reservoir rock and a tubular conduit for the well fluids.

Additionally, magnet-particle examination shall be performed by the wet fluorescent method. Additionally, magnetic particle examinations shall use the wet fluorescent method. The surface pressure control is provided by a Christmas treewhich is installed on top of the wellhead, with isolation valves and choke equipment to control the flow of well fluids during production. PSL 3 — Required Non-Destructive Testing Material NDE— Volumetric Examination As far as practical, the entire volume of each part shall be volumetrically inspected radiograph or ultrasonic after heat treatment for mechanical properties and prior to machining operations that limit effective interpretation of the results of the examination.

Oil wells Oil platforms Petroleum production Oilfield terminology. Wellheads are typically welded onto the first string of casing, which has been cemented in place during drilling operations, to form an integral structure of the well.

Some companies may require additional testing other than what is listed above. This page was last edited on 1 Juneeditoin From Wikipedia, the free encyclopedia. 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.

While drilling the oil well, surface pressure control is ecition by a blowout preventer BOP. In exploration wells that are later abandoned, the wellhead may be recovered for refurbishment and re-use.

The primary purpose of a wellhead is to provide the suspension point and pressure seals for the casing strings that run from the bottom of the hole sections to the surface pressure control equipment.
