| Aims of Module | |||
|---|---|---|---|
| The module aims to develop an understanding of well engineering fundamentals in terms of issues relating to casing functions, design considerations and factors affecting casing design in order to maximise safety, increase well life and reduce well cost. | |||
| Learning Outcomes for Module | |
|---|---|
| On completion of this module, students are expected to be able to: | |
| 1 | Identify the factors that determine the minimum setting depth of casing and appraise the top down and bottom-up casing setting selection and discuss the functional and loading requirements of various casing strings, in order to make a complete design selection for a wide range of different well conditions. |
| 2 | Perform the equivalent circulation density (ECD) calculations. |
| 3 | Develop casing program (hole geometry, casing seat, casing type and diameters and mud weight) and determine performance properties of casing. |
| 4 | Select casing weights, grades and coupling types for different well conditions (high temperature, high pressure wells, horizontal wells). |
| 5 | Analyse casing design using computer programmes and optimise casing programmes. |
| Indicative Module Content |
|---|
| Introduction to casing design: Casing design, purpose of casing, levels of casing design, types and functions of casing, string definitions. Preliminary casing design: Minimum casing diameter, minimum casing setting depths, lithological casing seat selection, factors impact on casing selection depth, preliminary casing design process, casing scheme selection, wellhead selections, casing wear prediction, design software. Detailed casing design process (drilling and production): pressure and temperature profiles, calculation of performance properties under load conditions, calculation of collapse and burst loads based on maximum loading condition, calculation of tension based on suspended weight, shock load, bending force, compression and buckling load and analysis of biaxial and triaxial loads. Principles of casing design and program optimisation: Kick tolerance and ECD calculations, selection of casing sizes, casing seating depths based on pore and fracture pressure data, selection of weights, couplings and grades for conductor, surface, intermediate and production casing for different well conditions and use computer software to optimise casing selection. Pressure testing. Corrosion, wear and fatigue: Influence of corrosion on casing strength, influence of wear on casing strength, influence of fatigue on casing strength. Casing depth selection: Shallow gas zones, lost circulation zones, formation stability, directional well profile, future sidetracking requirements, hole cleaning. Casing design for special case wells: Casing design and practice for high temperature, high pressure wells, squeezing salt wells, deepwater wells and directional and horizontal wells. |
| Module Delivery |
