This project was started as an assignment for my Drilling Engineering II course. Later on, I worked on it and made some improvements, and added a user interface. It takes several inputs, these are:
- Depth, feet
- Mud Weight, ppg
- Expected formation pressure gradient, psi/ft
- Collapse design factor
- Joint strength design factor
- Yield strength design factor
- Internal yield design factor
Also, the casing size should be chosen from the interface. I only created a list of 7'' and 9 5/8'' casings, which I believe should be enough for the moment. After the inputs are given and the casing size is chosen, the design process takes place and gives a table. This table includes the following:
- Section
- Interval, ft
- Length, %
- Casing Grade
- Casing Weight
- Coupling Type
Example figures are shown below.
Note: The program still contains some bugs since it is still in the development stage.
