Petrochina, the developer of Iraq’s Halfaya oil field has issued a tender for the provision of general engineering services (GES) for the second phase of its surface facilities at the field in the southern Missan province.
Petrochina has divided the scope of work for the GES contract into seven packages and asked firms to submit bids by 7 February, according to sources close to the project.
The development includes new 100,000 barrel a day (b/d) central crude oil processing facilities (CPFs) and a 220 million cubic feet a day (cf/d) gas processing plant, as well as water supply facilities, a power plant and export and infield pipelines.
The Oil Ministry estimates that the associated gas from the fields contain 0.5 per cent hydrogen sulphide, which will be processed in a dehydration unit and sulphur recovery unit at the plant.
The contractor will also carry out topographical and geotechnical surveys for the basic design of the packages, prepare tender documents, identify long lead items
Petrochina plans to commission the Phase-2 facilities by the end of 2013. The design period for the packages is approximately five months, although the central processing facilities and gas plant will take up to seven months to complete.
The 4.1 billion barrel oil field is being developed by Petrochina, a subsidiary of state-owned China National Petroleum Corporation (CNPC). It awarded a $162.5m engineering, procurement and construction (EPC) contract to its sister company, China Petroleum Engineering Construction Company (CPECC) last May for work on the first phase of development, including CPF-1.
Petrochina leads a consortium with France’s Total, Malaysia’s Petronas and state-owned South Oil Company (SOC) along with Missan Oil Company (MOC) to increase production to 6 million b/d by 2020, from 2.7 million b/d currently. The group will be paid a remuneration fee of $1.40 per barrel.
