Wooden box for API 6A 35MPa PR1 and PR2 Double-channel completionwellhead and christmas tree for oil and gas
A wellhead and Christmas tree (X-mas tree) are important pieces of equipment in oil and gas industry. In oil production, the X-mas tree rests on the wellhead.
X-mas tree is an assembly of fittings, valves and spools that help to control the flow of oil and gas. This allows for surface regulation and monitoring of the production process.
Moreover, the X-mas tree may provide other functions such as chemical injection points, well intervention, pressure relief and well monitoring points.
A wellhead is used both during oil and gas drilling and production. During drilling, it is used without the X-mas tree while during production, the two are used together.
Companies that manufacture wellhead and X-mas tree must fabricate these components in accordance with the API 6A standards. The API standards specify the following: performance criteria, choice of materials, dimensions, design, testing and inspection, among other parameters.
The two parts must pass certain tests and routine inspections to ensure consistency and optimal production in oil and gas production. It is for this reason that API insist on certain Performance Requirement (PR) tests that all wellhead and X-mas tree should meet.
About Performance Requirement (PR) in Oil & Gas Industry
API 6A, 19th Edition highlights all components of the wellhead and X-mas tree that should be subjected to a number of performance verification testing. Therefore, manufacturers of these accessories must perform two levels of testing:
In fact, this is a requirement even before the wellhead and X-mas tree are monogrammed by the manufacturer.
Mostly, the PR 1 is adopted as a minimum requirement. The wellhead and X-mas tree manufacturers perform these tests at room temperature, pressure and specific mechanical cycles.
