To break through the production bottleneck of old oil fields and ensure stable supply of oil and gas in the medium and long term, QatarEnergy is making every effort to promote the construction of Dukhan Field DPFU Phase 1B. The project will add supporting equipment for oil and gas processing, water injection, and oil extraction, fill the existing production gaps, strengthen the long-term stable production capacity of the oil field, and meet Qatar's oil and gas production needs for decades to come.

The prominent position of oil production capacity

Dukhan Field is located 80 kilometers west of the capital city of Qatar, Doha. It is the largest onshore oil field in the country, stretching 80 kilometers and 8 kilometers wide. Since its production in 1949, it has been the core pillar of Qatar's crude oil production.

At present, the oil field relies on the three major reservoirs of Arab C, Arab D, and Uwainat to extract oil and gas, and the produced oil and gas mixture is uniformly sent to multiple Degassing Stations in the field for separation and processing. To meet long-term mining needs, Qatar Energy has developed a phased plan for modernizing and upgrading ground facilities, which is divided into three stages: completing Phase A renovation from 2019 to 2022; The Phase B project from 2023 to 2027 is currently being implemented; After 2028, long-term expansion projects will be carried out to continuously iterate oilfield production infrastructure.

Implementation of general contracting mode

The Phase B project of this project adopts the EPIC integrated general contracting model for design, procurement, installation, and commissioning. The winning contractor is fully responsible for the detailed design, equipment procurement, on-site construction, project management, commissioning, trial operation, and performance acceptance of the project, and ultimately delivers a complete oil and gas production facility that can be directly put into operation. The EPIC contract is divided into two parts, the second and third, with independent technical documents but belonging to the same general contracting project, which will simultaneously promote construction.

The second part is the capacity expansion project, which includes three major renovation contents: firstly, upgrading the Degassing Stations gathering and transmission manifold, adding 56 new wellhead access slots, and improving pipeline, instrument, electrical, and civil engineering facilities to enhance the efficiency of new well access; The second is to expand the PS-9 pressurized water injection system, add pressurized water injection pumps, renovate the substation and switchgear, and strengthen the two main water injection pipelines through testing and reinforcement; The third is to renovate the gas lift main station, add 108 gas lift well access ports, and provide supporting chemical injection systems and civil engineering to ensure the smooth operation of the new drilling. This part of the FEED has been completed by a local consulting company in Qatar, and the general contractor only needs to undertake and implement the subsequent construction design work.

The third part is the facility optimization and safety upgrade project, focusing on on-site safety upgrading and renovation of old facilities: adding 3 crude oil export pumps and 2 produced water transfer pumps to the North Hatiye degassing station; Demolition of abandoned control rooms and old infrastructure within the site; Install emergency flushing and eye washing devices with cooling function for 7 degassing stations; Install a dual isolation safety system for the valve of the sewage settling tank; At the same time, special maintenance stairs will be installed on the centrifuge platforms of 7 degassing stations to fully address the safety shortcomings on site.

Build a solid foundation for stable production

Qatar Energy stated that the core purpose of this upgrade project is to eliminate operational bottlenecks in existing production facilities, enhance the safety and stability of the oilfield production system, and provide solid infrastructure support for subsequent exploration and development of the oilfield. Previously, Dukhan Field had completed multiple rounds of supporting upgrades, including separator renovation, optimization of produced water systems, and expansion of pumping stations. All renovations focused on improving production efficiency, extending the service life of the oilfield, and achieving national oil and gas production targets. Keywords: Qatar Dukhan Field

Industry insiders analyze that Qatar is continuously promoting its strategy of increasing oil and gas production and modernizing infrastructure. The Dukhan Field series upgrade project will continue to release full chain market opportunities such as EPC general contracting, equipment supply, automation control, electrical instrumentation, and oilfield operation and maintenance. Chinese engineering companies and equipment manufacturers with rich experience in onshore oil and gas project construction are expected to seize this and subsequent project orders and deepen cooperation in the Middle East oil and gas infrastructure field with their technological and cost advantages.Editor/Gong Ziwei
