Wellhead training program assist wellhead buyers, wellhead quality controls, wellhead designers, or wellhead engineers to manufacture, purchase, inspect, and design a wellhead component or a wellhead system based on API 6A wellhead equipment specification. Wellhead design calculation address the methods in designing a wellhead component based on the industrial codes or good engineering practices to calculate the components at appropriate design factors (or safety factors); Wellhead assembly diagram is designed as specified by a well completion engineer in an oil company.
API 6A Basics
API 6A is an International Standard that specifies requirements and gives recommendations for the performance, dimensional and functional of surface wellhead and Christmas tree.
- API 6A Monogram: Indications of the product comply with standards
- Wellhead Buying Guide
- Recommend material for well conditions
- How to order wellhead and Christmas tree equipment
- Temperature Class: K, L, N, P, R, S, T, U, V, S, Y
- Material Classes: AA, BB, CC, DD, EE, FF
- Nace: Limits for materials in H2S service
- Quality Control
- Product Specification Levels (PSL)
Wellhead Design Calculation:
The design calculation will address the factors in designing a wellhead component, and the industrial codes or good practices to calculate the components at appropriate design factors (or safety factors).
- Design Consideration: Pressure, Temperature, Material, Nace, Corrosive Well Fluid
- Design methods: ASME Method, Von Mises, Proof Testing, etc.
- Casing and Tubing String Consideration
- Membrane Stress Intensity
- FEA Analysis
- Wall Thickness Criteria
- Bearing and Direct Shear
- Bolting Calculations
Wellhead 2D and 3D Diagram
Wellhead assembly diagram is designed as specified by a well completion engineer in an oil company. It illustrates how the bottom of wellhead is connected with casing, how the outlets are connected the proposed piping, how the product tubing are hanging, and how the wellhead system to accommodate the control lines or instrument cables. A diagram is drawn by using a 2D AutoCAD or 3D CAD software.
