The "Day Tour" in Drilling and Well Completion: A 12-Hour Shift in the Round-the-Clock Operation

In the world of drilling and well completion, where operations often run around the clock, the term "day tour" (pronounced "tower") takes on a specific meaning. It refers to one of two 12-hour shifts worked by a drilling or workover crew, typically during daylight hours.

Why Two Tours?

The concept of day and night tours is born from the need for continuous operation in drilling and well completion. These processes can be complex and time-sensitive, often involving multiple stages and demanding equipment. To maximize efficiency and minimize downtime, a 24/7 work schedule is implemented, allowing for continuous progress.

The Day Tour: A Crucial 12 Hours

The day tour, typically running from 7 am to 7 pm, serves as a crucial period for a variety of tasks:

Equipment Setup and Dismantling: The daylight hours are ideal for setting up, moving, and dismantling heavy equipment, ensuring clear visibility and safer handling.
Critical Operations: Certain drilling operations, like tripping in and out of the hole, may be more efficiently executed during the day due to better lighting and visibility.
Coordination and Supervision: Daytime allows for easier communication and collaboration between crew members, supervisors, and support personnel.
Maintenance and Repairs: Any necessary equipment maintenance or repairs can be carried out with greater precision during daylight hours.
Logistical Activities: Daylight provides better visibility for loading and unloading equipment, transporting materials, and managing supplies.

The Day Tour's Impact

The day tour plays a vital role in the overall success of drilling and well completion projects:

Improved Efficiency: By maximizing the use of daylight hours, operations can be carried out with greater speed and accuracy.
Reduced Downtime: By minimizing the need for work stops during the day, the overall project duration can be shortened.
Enhanced Safety: The visibility and ease of communication during the day significantly improve safety for crew members.

Beyond the Day Tour:

While the day tour is a crucial component, it is only one part of the continuous 24-hour operation. The night tour, often referred to as the "night shift", handles the essential tasks that can be effectively completed under the cover of darkness.

In conclusion, the "day tour" in drilling and well completion is a critical 12-hour shift that leverages the advantages of daylight hours for optimal efficiency, safety, and productivity. It is a testament to the dedication and resilience of the crews working tirelessly to bring oil and gas to the world.

Exercise: The Day Tour Schedule

Instructions: A drilling crew is working on a 24-hour schedule, with a day tour and a night tour. The day tour begins at 7:00 AM and ends at 7:00 PM.

Task:

Create a sample schedule for the day tour. Include at least 4 different activities, such as equipment setup, drilling operations, maintenance, and breaks.
Assign approximate time durations for each activity.
Explain why you chose those specific activities and their time allocations.

Exercice Correction

Here's a sample schedule for the day tour, along with explanations:

Sample Day Tour Schedule:

| Time | Activity | Duration | Explanation | |----------------|---------------------------|----------|------------------------------------------------------------------------------------| | 7:00 AM - 8:00 AM | Safety Briefing & Equipment Check | 1 hour | Ensures everyone is aware of safety protocols and equipment is in good working order. | | 8:00 AM - 12:00 PM | Drilling Operations | 4 hours | This is the core activity, allowing for maximum drilling progress during daylight hours. | | 12:00 PM - 1:00 PM | Lunch Break | 1 hour | Provides time for crew members to rest and refuel. | | 1:00 PM - 4:00 PM | Equipment Maintenance | 3 hours | Allows for any necessary maintenance to be conducted with good visibility. | | 4:00 PM - 5:00 PM | Tripping Out of the Hole | 1 hour | This task is often done during the day for better visibility. | | 5:00 PM - 6:00 PM | Logistical Operations | 1 hour | Time to handle supplies, equipment transfers, etc. | | 6:00 PM - 7:00 PM | De-briefing & Wrap-Up | 1 hour | Review of the day's progress, planning for the night tour, and assigning tasks. |

Explanation:

Drilling Operations: This is the most critical task, so it gets the most time during daylight hours.
Equipment Maintenance: This is essential for safety and efficiency. The day tour offers ideal conditions for detailed checks and repairs.
Tripping: This is a time-consuming activity best done during daylight for better visibility and accuracy.
Logistical Operations: This is crucial for maintaining a smooth flow of materials and equipment.

This is just a sample schedule, and actual schedules can vary based on specific project needs and requirements.
