## Drilling Process Execution Time

It takes approximately 28 days to complete the drilling process. A complete breakdown of the time required to complete each stage has been provided in the attached spreadsheet. Additionally, a summary of the findings has been provided below. ### Surface Hole Drilling

- Surface hole drilling is expected to end after seven days since the time the drilling began.
- 168 hours are required to complete this stage.

### Surface Casing and Cementing

- Surface casing and cementing of the initial hole is expected to end after nine days since drilling began.
- 48 hours are required to complete this stage.

### Vertical and Horizontal Drilling

- Vertical and horizontal drilling is expected to end after 16 days since the drilling began.
- 168 hours are required to complete this stage.

### Production Casing

- Production casing is expected to end after 28 days since surface hole drilling began.
- 288 days is the approximated time for the drilling process.

### Research Strategy

To provide the approximated number of hours needed to complete each stage of the drilling process, the research team used a drilling animation video produced by Chesapeake Energy. The animation video had time stamps for when each stage was completed. The time was given in days in the video and therefore had to be converted to hours. Furthermore, the time stamps were for when each stage was completed. The team, therefore, had to subtract the end time for one stage from the end time of the next stage to get the actual approximated time for each stage. It is, however, prudent to note that during the drilling process, the rig is in constant operation for the whole 24 hours in a day. ### Triangulation

Surface Case Drilling

- Hours required to complete stage = 7 days * 24 hours =168 hours

Surface Casing and Cementing

- Days required to complete stage = 9 days — 7 days = 2 days
- Hours required to complete stage = 2 days * 24 hours = 48 hours

Vertical and Horizontal Drilling

- Days required to complete stage = 16 days — 9 days = 7 days
- Hours required to complete stage = 7 days * 24 hours = 168 hours

Production Casing

- Days required to complete stage = 28 days — 16 days = 12 days
- Hours required to complete stage = 12 days * 24 hours = 288 hours
