Closed-Loop System in Land Drilling Rig

Abstract Closed-loop system in land drilling rig are analyzed in this paper, which considers a first practice "no waste pit". The focus is on the skip-and-ship method for drilling cuttings disposal and excess drilling fluid management. By examining the design, implementation, and best practices of the recycling system, the study aims to enhance waste management, reduce environmental impact, and optimize drilling operations for improved safety and cost-effectiveness. The study will experimentally investigate the impact of closed-loop system in land drilling rig as an alternative to conventional drilling methods that cause environmental issues. This study evaluates a closed-loop system's effectiveness in managing drilling waste, its environmental impact, safety and cost. The goal is to promote sustainable drilling and reduce environmental harm. The experimental investigation of closed-loop system in drilling rig demonstrated significant waste management improvements, achieving 100% restoration of a 9,285 ft well with six sections. A dry location with no waste pit, 263 skips transported 1,709 tons and 5,786 BBLs of waste drilling fluid, including harmful oil-based mud. Drilling fluid consumption reduced by 6%, and the system led to zero spills, highlighting its potential to minimize environmental impacts. The closed-loop system effectively managed drilling waste. Integrating skip-and-ship methods for drilling cuttings disposal and waste fluid management provided robust and efficient waste reduction and restoration. By eliminating spills, the system mitigated environmental risks, improved safety and cost-effectiveness, saving cost from skip-and-ship costs needed for two waste pits. Recycling 63% of waste mud was achievable with the closed-loop system. Closed-loop system in drilling rig offer immense potential for waste restoration, reducing environmental impacts, and maintaining zero spills. Implementing closed-loop system and optimizing waste management practices can lead the drilling industry towards sustainable and environmentally responsible operations. The study emphasizes the importance of ongoing research and development in closed-loop technology, paving the way for further advancements in drilling waste management, environmental preservation, and operational efficiency. This paper presents novel insights into closed-loop system in drilling rig, emphasizing their potential to eliminate waste pits and spills through skip-and-ship methods for cuttings disposal and recycling opportunities. Highlighting environmental, safety, and cost benefits, the study explores challenges and future trends, advancing the industry's comprehension of sustainable drilling practices. The paper promotes the broader adoption of closed-loop system as standard rig equipment.
