Advantages of Using a Walking System vs. Skidding System for Onshore Oil Rigs
In the competitive and fast-paced world of land-based oil rig operations, efficiency, safety, and cost-effectiveness are paramount. As oil rigs move from one drilling site to another, the method of rig repositioning can make a significant difference in terms of operational success. Two primary methods—walking systems and traditional skidding systems—are commonly employed for this purpose. While both offer solutions for moving rigs, the walking system has increasingly become the preferred choice among oil and gas operators due to its unparalleled benefits.
Flexibility and Mobility
One of the most compelling advantages of a walking system lies in its advanced mobility and flexibility. Unlike skidding systems, which are limited to movement along a predetermined path, walking systems provide multidirectional movement—allowing rigs to “walk” in any direction, across a full 360 degrees. This capability provides an unmatched level of precision and agility. Walking systems can navigate distances of over 500 feet without requiring additional heavy transportation equipment, making them far more versatile than skidding systems.
Moreover, the flexibility of a walking system is not just about speed and distance; it also reduces downtime between drilling operations. By eliminating the need to disassemble and reassemble rig components, walking systems significantly reduce the time spent on rig relocation. This also lowers the risk of equipment wear and tear, extending the operational lifespan of critical rig components. In terms of weight capacity, walking systems are often capable of supporting a broader range of rig sizes and weights, making them a robust solution across diverse operational environments.
Time and Cost Efficiency
In the oil and gas industry, where time equates to money, operational efficiency is crucial. The more time spent on rig relocation, the greater the associated costs. Walking systems streamline the entire process of rig repositioning by removing the need for complex dismantlement, transportation, and reassembly processes that are typical of traditional skidding methods. This allows operators to move rigs swiftly, getting them back into operation much faster and at a significantly lower cost.
Skidding systems, by contrast, often result in higher downtime, as they require external resources such as trucks and cranes to assist in rig movement and relocation. This reliance on external equipment adds both time and expense to the operation, making skidding systems less cost-effective in comparison. In contrast, walking systems are self-contained, with no external transportation needs, enabling operators to move rigs independently, reducing both the time and cost involved.
To estimate the savings when using a drilling rig with a Columbia Walking System compared to a skidding system for drilling four wells on a pad, we can consider several factors, including time efficiency, rig rate, and operational downtime.
When drilling four wells on a pad, the Columbia Walking System offers greater efficiency compared to a skidding system, primarily in repositioning time, which translates to cost savings.
Key Assumptions:
- Distance Between Wells: 20 feet
- Daily Rig Rate: $35,000
- Hourly Rig Rate: $1,458/hour ($35,000 ÷ 24 hours)
- Drilling Time per Well: 12 hours
Repositioning Time Estimates:
- Columbia Walking System: ~1.5 hours per move → 4.5 hours total
- Skidding System: ~5 hours per move → 15 hours total
Total Time & Cost Comparison:
Estimated Savings:
$91,974 – $79,634 = $12,340
Conclusion:
By using a Columbia Walking System instead of a skidding system to drill four wells, you could potentially save around $12,340 in rig costs due to reduced repositioning time. This estimate can vary based on specific project conditions, but it highlights the efficiency advantages of the walking system.
Safety and Environmental Concerns
Safety remains a top priority in any oil and gas operation, especially during the rig moving process, which can pose significant hazards. Walking systems provide a notable safety advantage over traditional skidding systems by minimizing manual intervention and reducing the risks associated with handling large, heavy equipment. These systems can be remotely controlled, allowing operators to manage rig movement from a safe distance, reducing exposure to potential accidents or injuries.
Additionally, walking systems contribute to a cleaner and more sustainable operation. With fewer heavy trucks and vehicles required for transportation, there is a significant reduction in emissions, contributing to lower environmental impact. This is particularly important as the industry increasingly focuses on adopting greener, more environmentally responsible practices.
Technological Capabilities
Walking systems are at the forefront of technological innovation in the oil and gas industry. Their adaptable design not only enhances current operations but also positions rigs for future technological advancements. These systems can be integrated with cutting-edge automated features and remote-control capabilities, further improving operational efficiency and safety. As technology continues to evolve, walking systems will play a pivotal role in enabling more responsive drilling strategies, helping operators optimize production and adjust to market dynamics in real-time.
Conclusion
In conclusion, the adoption of walking systems for land-based oil rigs offers significant benefits that align with the industry’s growing demands for greater efficiency, enhanced safety, and sustainability. The ability to rapidly and cost-effectively relocate rigs, coupled with the system’s flexibility, safety features, and capacity for technological integration, makes walking systems an increasingly popular choice for oil and gas operators worldwide. As technological innovation continues to shape the future of the oil and gas industry, walking systems are set to play an essential role in driving operational excellence, maximizing earnings, and increasing return on investment for land rig operators across the globe.
