Wellhead (casing head and spools)

Surface wellhead without a tree, on a conductor and landing plate. It has a casing head plus casing and tubing head spools (one to three sections by height), studded annulus outlets with gate valves, B16.5 crossovers and gauges on one side and VR-plugged blind outlets on the other, hanger lockdown screws, secondary-seal test ports and the SCSSV control-line exit. The top is either a blind flange with a bleed valve and gauge, or an open ring-joint face ready for a tree or BOP. The annulus-* ports are numbered from the tubing head down.

Installation

Copies wellhead/wellhead-housing.tsx and the shared lib/ into src/components/deck-twin/. Needs three, @react-three/fiber and @react-three/drei. See installation for the manual route.

Usage

import { Canvas } from '@react-three/fiber'
import { OrbitControls } from '@react-three/drei'
import { Stage } from './components/deck-twin/lib/stage'
import { WellheadHousing } from './components/deck-twin/wellhead/wellhead-housing'

export default function Scene() {
  return (
    <Canvas shadows camera={{ position: [8, 5, 9], fov: 35 }}>
      <Stage>
        <WellheadHousing />
      </Stage>
      <OrbitControls makeDefault />
    </Canvas>
  )
}

Props

P&ID

A stack of rectangles (casing head at the bottom, casing and tubing head spools above) on the conductor, each with side annulus outlets carrying gate valves and gauges; a blind flange or tree adapter on top.

Only annulus side outlets and no wing / choke means a wellhead without a tree (suspended well, or below a BOP). With a valve stack and choke on top it is a christmas-tree. ISA codes here: PI = annulus; PT = annulus.

For agents

Machine-readable entry with props, ranges, defaults and ports:

Or fetch /r/wellhead-housing.json, or copy a ready-made instruction:

Add the Deck Twin "Wellhead (casing head and spools)" component to this project. Run `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz add wellhead-housing` (it copies the file and the shared lib into src/components/deck-twin/), then `npx -y https://decktwin.com/cli/deck-twin-0.2.2.tgz info wellhead-housing` for its props, ranges and ports. Render <WellheadHousing /> inside a React Three Fiber <Canvas shadows>, wrapped in <Stage> from src/components/deck-twin/lib/stage. Set props from my data (metres, NPS in inches, ASME class) and leave the rest at defaults. Install three, @react-three/fiber, @react-three/drei and @types/three if they're missing.
