Course Objectives:
Participants will be able to design casings for any well: onshore, offshore, high pressure and high temperature wells, horizontal and multilateral wells.
Course Outline:
- Steel properties and API casing strengths
- Fracture gradient: A Rock Mechanics approach
- Casing seat selection: graphical methods, refinements, case histories
- Casing design criteria: Collapse , Burst, Tension
- Detailed Collapse design: partial and full evacuation; when to use each
- Kick tolerance and kick profiles: industry approach
- Burst Design: Casing full of gas, limited kick design
- Detailed tension design: self weight, shock loading, pressure testing, bending forces, thermal forces, pressure-area method
- Offshore conductor design
- Production casing design: tubing leak approach
- Design factors: typical values; what do they mean
- Casing design methods for: Exploration, Development, Horizontal and HPHT
- Triaxial loadings
- API load lines
- Stress Ellipse including API load lines
- Load cases
- Temperature effects and trapped annular pressures
- Buckling analysis
- Sour gas consideration: special casing grades and effects of temperature, NACE and European standards
- Connections: API and premium, methods of selection
- Well suspension and abandonment
- Casing wear
- Complete well design
