link 188bet cho dien thoai Innovative Solution for Repairing Damaged Oil Wells Helps Save Tens of Billions of VND
At link 188bet cho dien thoai 2024 Vietnam Science and Technology Innovation Awards (VIFOTEC), held on May 28 in Hanoi, link 188bet cho dien thoai project titled “Design of a Well Completion Assembly for Repairing Oil and Gas Wells Under Complex Conditions” by a research team from link 188bet cho dien thoai PetroVietnam Exploration Production Corporation (PVEP) was awarded First Prize.
This project offers a breakthrough solution to a persistent challenge in link 188bet cho dien thoai petroleum industry: restoring damaged production wells with high safety and reduced costs, thereby addressing practical needs in oilfield operations.
During oil and gas exploitation in Vietnam, numerous wells become inoperable due to long-term usage or external factors, resulting in production tubing breaches, casing failures, or downhole blockages. These conditions severely reduce oil output and can even lead to complete production shutdown. Conventional repair approaches require retrieving link 188bet cho dien thoai entire old well completion system and replacing it with a new one—a process fraught with high costs, significant risks, and extended downtime.
Lead engineer Nguyễn Quốc Hưng explained that link 188bet cho dien thoai team aimed to develop a more efficient and technically safe solution that would enable well repair without having to replace link 188bet cho dien thoai entire system, while also restoring production and ensuring readiness for future well interventions.
Based on this goal, link 188bet cho dien thoai team conducted pilot implementation on a specific well owned by link 188bet cho dien thoai Vietnam National Energy Group. They proposed a specially designed technical assembly that allows link 188bet cho dien thoai integration of a new well completion assembly with link 188bet cho dien thoai remaining usable components of link 188bet cho dien thoai old system. This eliminates link 188bet cho dien thoai need to retrieve link 188bet cho dien thoai entire complex downhole equipment to link 188bet cho dien thoai surface, yet still enables link 188bet cho dien thoai well to resume production and remain intervention-ready.
link 188bet cho dien thoai proposed solution enables link 188bet cho dien thoai installation of a new production casing column and establishes a connection with link 188bet cho dien thoai retained lower wellbore completion components. This configuration also allows for link 188bet cho dien thoai application of gas lift techniques, enhancing link 188bet cho dien thoai oil recovery factor.
link 188bet cho dien thoai project’s effectiveness was proven through field trials on well PL-1P in link 188bet cho dien thoai Pearl Field, located offshore in link 188bet cho dien thoai Cuu Long Basin of Vietnam's East Sea. In under 20 days, link 188bet cho dien thoai well was restored to production with an output of 1,830 barrels per day—three times link 188bet cho dien thoai original target. link 188bet cho dien thoai repair costs were reduced by approximately USD 850,000 compared to traditional methods, owing to partial reuse of existing equipment and shortened rig operation time.
Co-project leader engineer Nguyễn Văn Khương noted that retaining usable well components not only saves time and costs but also significantly mitigates technical risks. More importantly, link 188bet cho dien thoai well remained stable and yielded high production post-repair.
link 188bet cho dien thoai research team emphasized that link 188bet cho dien thoai project demonstrates Vietnam’s capability to independently master technologies previously reliant on foreign experts and imported equipment. Successfully designing and implementing this well repair solution represents a new direction for link 188bet cho dien thoai domestic oil and gas industry—reducing dependence on foreign technology and enabling flexible application across wells with similar damage scenarios.
Commenting on Resolution 57-NQ/TW issued by link 188bet cho dien thoai Politburo—which aims to promote scientific and technological advancement aligned with practical implementation—engineer Nguyễn Quốc Hưng highlighted link 188bet cho dien thoai policy as a critical shift in perception and mechanism. He emphasized that if current frameworks are improved and effectively implemented, and stronger links are formed between scientists and enterprises, applied research projects will be better positioned to deliver real-world impact and scale more rapidly and effectively.
