Doha: Qatar Petroleum (QP) has announced plans to invest over QR40bn in the re-development of the existing Bul Hanine offshore oilfield located about 120km to the east of the Qatari coastline.
The project, which is currently at the pre-FEED stage, is one of the largest to be managed and executed by QP. It is designed to prolong the field’s life by countering its production decline and doubling its current oil production rate.
Commenting on the redevelopment plans, Minister of Energy and Industry and Chairman of QP H E Dr Mohammed bin Saleh Al Sada (pictured), said: “This important project is part of a development and production strategy based on maximum recovery of reserves through the longest possible plateau of sustainable production levels. It will help boost Qatar’s oil production capacity and reinforce its position as a reliable energy provider.”
Dr Al Sada expressed pride in what has been achieved so far in the development of Qatar’s oil & gas fields and assets. He said “Qatar Petroleum’s excellent track record in managing and executing mega projects over the years and the experience it has accumulated throughout will pave the way for the successful execution of this important and strategic project.”
The Minister pointed out that “the Bul Hanine redevelopment constitutes another step in the utilisation of Qatar’s hydrocarbon wealth and is consequently a key element in the implementation of the Qatar National Vision as launched and guided by H H Sheikh Tamim bin Hamad Al Thani, the Emir of the State of Qatar.”
“In addition to sustaining economic growth and providing financial stability, this re-development is also an important step towards building the capabilities of local resources by providing a unique experience opportunity for Qatari engineers,” Dr Al Sada concluded.
QP is implementing a redevelopment programme for its oil fields, which were originally developed with older technology, in order to ensure steady production levels. Major reservoir and field-wide studies have been undertaken — including seismic surveys — in order to re-assess the reserves and the long-term production prospects for each field. This has been carried out using Improved Oil Recovery Techniques and Full Field Redevelopment Plans, as well as the latest cutting-edge technology and powerful computer modeling and processing.
The magnitude of this investment reflects the extent of project scope that includes new offshore central production facilities and a new onshore gas liquids processing facility at Mesaieed. This will be marked by a massive drilling campaign of about 150 new wells between now and the year 2028.
New wells will be drilled from the existing/modified well-head jackets, as well as from 14 new wellhead jackets. Both new and modified wellhead jackets, in addition to associated production and injection flowlines, will form parts of the project works.
All wellheads stream fluids will be processed in the new offshore central complex, comprising of production, compression, utility and living quarter platforms, with topsides weight ranging from 4,000 to 14,000 tonnes.
Produced oil will be sent to Halul Island for export. The produced sour rich gas of about 900 million cubic feet per day will travel via a new 150km subsea pipeline to a new gas treatment facility in Mesaieed for products recovery, where lean sweet gas will be sent via a new subsea pipeline back to the new off-shore facilities for compression and injection.
The redevelopment is part of a comprehensive plan currently being implemented to raise the efficiency of producing fields as well as the implementation of various well drilling programs to increase crude oil reserves in fields like Bul Hanine and Dukhan.
