State-owned Qatar Petroleum (QP) is investing more than QR40bn in the re-development of the Bul Hanine offshore oil field, which is located 120km east to the state’s coastline.
The redevelopment, which includes drilling of 150 new wells between now and 2028, is part of a comprehensive plan to raise the efficiency of producing fields as well as the implementation of various well drilling programmes to increase crude oil reserves in fields like Bul Hanine and Dukhan.
“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,” said HE the Minister of Energy and Industry Dr Mohamed bin Saleh al-Sada.
“It will help boost Qatar’s oil production capacity and reinforce its position as a reliable energy provider,” said al- Sada, who is also QP’s chairman.
The project, which is currently at the pre-FEED (front-end engineering design) 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.
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 wells between now and 2028.
New wells will be drilled from the existing/modified well-head jackets as well as from 14 new wellhead jackets, a QP spokesman said, adding both new and modified wellhead jackets, in addition to associated production and injection flow-lines, would form parts of the project works.
All wellheads stream fluids will be processed in the new offshore central complex, comprising production, compression, utility and living quarter platforms, with topsides weight ranging from 4,000 to 14,000 tonnes. The produced oil will be sent to Halul Island for export. The produced sour rich gas of about 900mn cubic feet per day will travel via a new 150-km 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 of Bul Hanine constitutes another step in the proper utilisation of Qatar’s hydrocarbon wealth and is a key element in the implementation of the Qatar National Vision 2030.
“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,” al-Sada said.
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 modelling and processing.
