China’s CPECC wins Iraq gas upgrade project

20 March 2023

China Petroleum Engineering & Construction Corporation (CPECC), a subsidiary of China National Petroleum Corporation (CNPC), has been awarded the contract to upgrade a gas compression system at Iraq’s Halfaya field.

The contract was signed on 4 March after nearly three years of negotiations, according to a statement issued by CPECC.

Commercial bid submission for the project took place in July 2020.

The contract uses the engineering, procurement, construction and commissioning model and is focused on improving the gas compression system at the facilities known as Central Processing Facility (CPF) 1 and CPF 2.

The scope of the project includes:

CPF 1 gas compression system upgrade

  • Installation of two high-pressure compressors
  • Installation of two low-pressure compressors
  • Installation of two stabilised gas compressors
  • Installation of a condensate separator
  • Installation of two condensate pumps
  • Installation of power supply, control and telecommunications system
  • Installation of associated utilities

CPF 2 gas compression system upgrade

  • Installation of a high-pressure compressor
  • Installation of two low-pressure compressors
  • Installation of two stabilised gas compressors
  • Installation of a condensate separator
  • Installation of two condensate pumps
  • Installation of the power supply system
  • Installation of associated facilities

Halfaya is located in Maysan Governorate in southeastern Iraq and is one of the seven giant oil fields in the country.

The project client is a partnership led by PetroChina, a subsidiary of CNPC. It also includes France’s Total, Iraq’s state-owned South Oil Company and Malaysia’s Petronas.

The gas upgrade project will help to ensure a supply of natural gas and condensate to the nearby gas processing plant so that it can be put into operation.

This is expected to increase the volume of natural gas that is collected and processed.

As time passes, it is expected that the ratio of gas produced at the field will increase compared to the volume of oil produced.

This is expected to require the construction of a new set of high-pressure and low-pressure flares in CPF 1.

The design capacities of the high- and low-pressure flares are 185 million cubic feet a day (cf/d) and 14 million cf/d, respectively

The project supervisor is the UK-based engineering company Petrofac, and the contract period is 540 days.

Projects to develop the Halfaya gas field have seen significant delays in recent years.

In February 2022, Iraq’s Oil Ministry said it expects that the $1bn gas processing project, which is under execution at the oil field site, will start trial operations in mid-2023. Previously it was expected to be completed before the start of 2023.

Halfaya is Maysan province’s largest field, with estimated reserves of 4.1 billion barrels.

  • Eni completes $1bn Libya gas project

    20 October 2026

    Register for MEED’s 14-day trial access 

    Libya’s Mellitah Oil & Gas Company, a joint venture of Libya’s National Oil Corporation (NOC) and Italian oil and gas company Eni, has achieved mechanical completion on its Bouri gas utilisation project (GUP).

    In a statement, Eni said that start-up procedures are currently under way, enabling the recovery of associated gas produced from the Bouri field, which is located in Libya’s western offshore area.

    The main contract for the project, worth $1bn, was awarded to Italy’s Saipem in August 2023.

    The project involved the construction and installation of the new Bouri gas recovery module and related tie-in infrastructure that enables the recovery and treatment of gas that was previously flared.

    In its statement, Eni said that the project “represents one of the most significant emissions reduction initiatives in Libya’s energy sector”.

    It also said that it would contribute to improving the environmental performance of the country’s production system by reducing greenhouse gas emissions by approximately 1.5 million tonnes of carbon dioxide a year.

    The recovered gas will be supplied to the domestic market, adding about 700 million cubic metres a year and helping meet demand from the power generation sector.

    The project will also support additional gas volumes available for export to Europe through the GreenStream pipeline.

    Eni said: “The start-up of the Bouri GUP confirms the joint commitment of Eni and NOC to the development of Libya’s energy sector through initiatives that combine production growth, operational efficiency and environmental stewardship.

    “The project is part of a broader strategy aimed at enhancing the value of the country’s gas resources while reducing the emissions intensity of upstream activities.”

    Other key projects currently under way in Libya include the A&E Structures Project, which is focused on bringing new offshore gas resources onstream for both the domestic market and exports, as well as initiatives aimed at upgrading and optimising gas production and transportation infrastructures.

    Eni has been present in Libya since 1959, and the company’s equity production in the country in 2025 amounted to approximately 162,000 barrels of oil equivalent a day.

    The Bouri offshore field is part of Libya’s Block NC-41, located 120 kilometres north of the Libyan coast in the Mediterranean Sea.

    It was first discovered in 1976 at a depth of 8,700 feet. It is estimated to contain 4.5 billion barrels in proven recoverable crude oil reserves and 3.5 trillion cubic feet of associated natural gas, with an annual production potential of 6 billion cubic metres.

    The first development phase, costing nearly $2bn, was completed in 1990.

    This was immediately followed by a second development phase, which entailed drilling 55 new wells and constructing three additional platforms. Production began from the oil platforms DP4 and DP3 in August 1998.

  • Kuwait selects firms for power works at housing projects

    20 October 2026

     

    Kuwait’s Public Authority for Housing Welfare (PAHW) has appointed contractors for works covering the supply and installation of 132kV underground cables at South Sabah Al-Ahmad Residential City.

    The contracts relate to engineering, procurement and construction (EPC) packages for works for 28 main 132/11kV substations across four phases.

    According to sources, Egypt’s Elsewedy Cables has won contracts for phases 1 and 3, while China’s TBEA Shandong Luneng Taishan Cable Company has won contracts for phases 2 and 4 of the development.

    In April, MEED reported that PAHW had received at least five bids for each of the first two packages, with Elsewedy and TBEA offering $44m and $40.5m, respectively.

    The first contract (phase 1) covers seven substations in zones N9, N7 and N5. The second contract (phase 2) covers seven substations in zones N10 and N5.

    PAHW issued two further 132kV underground cable tenders for the South Sabah Al-Ahmad residential development at the end of May, as reported by MEED.

    This included a contract (phase 3) covering the supply, extension and maintenance of 132kV underground cables linked to seven substations serving the N5, N6, N8 and N10 districts. Egytech Cables, a subsidiary of Elsewedy, submitted an offer of $39.95m, the lowest of four bids.

    The other contract (phase 4) covers the supply, extension and maintenance of 132kV underground cables feeding eight main transformer substations serving the N1, N6 and N11 districts. 

    MEED reported in July that TBEA had submitted an offer of $44.06m for the contract.

    South Saad Al-Abdullah 

    Separately, PAHW has appointed contractors for power transmission works at the South Saad Al-Abdullah residential development.

    The local firm Sayed Hamid Behbehani & Sons has won a contract to supply, install and maintain 10 main 132/11kV transformer substations for the development’s third phase. 

    Another local firm, Al-Ahleia Switchgear, has won a contract to supply, install and maintain 10 main 132/11kV transformer substations for the project’s fourth phase. 

    As reported in August, the contractors submitted bids of $104.2m and $103.3m, respectively.

  • Taqa moves forward with Mirfa-Liwa scheme

    20 October 2026

     

    Taqa Transmission and Taqa Distribution are advancing a major water transmission and distribution scheme serving Mirfa, Madinat Zayed and Liwa in Abu Dhabi, sources told MEED.

    The project, originally estimated to cost $775m, has been in procurement for several years. According to sources, a request for proposals has been issued, with bids due on 5 January 2027.

    The initial submission deadline was 11 November, before it was extended.

    The project was previously tendered in December 2024, with contractors submitting bids for transmission and distribution packages in January 2025.  As of August, the bids were still under evaluation. It is unclear whether the latest tender represents a revised procurement process for the same scheme.

    The project comprises a water transmission system from Mirfa, alongside distribution networks serving farms and settlements in the western region.

    According to details seen by MEED, the latest scope includes a pumping station at Mirfa with a capacity of 128 million imperial gallons a day, about 125 kilometres of transmission pipelines to Muzairah, with branches to Madinat Zayed and Liwa Summit, and storage tanks at the three locations.

    The distribution network is divided into four geographic clusters covering Liwa East, Liwa West, Madinat Zayed and Seih Al-Kheir. The works include associated pipelines, pumping stations and storage facilities.

    The earlier procurement was structured as an engineering, procurement and construction scheme, divided between transmission and distribution works.

    As MEED understands, the latest tender is being pursued under a design, build and operate model, which extends the contractor’s responsibilities to operating the infrastructure after construction.

  • Contractors prepare prices for Adnoc Onshore field facilities project

    20 October 2026

     

    Contractors are preparing commercial bids for Adnoc Onshore’s project to build on-plot and off-plot facilities at the Rumaitha and Shanayel fields in Abu Dhabi’s North East Bab oil field cluster.

    The project will enhance and sustain crude output at Rumaitha and Shanayel at 45,000 barrels a day (b/d), supporting Adnoc’s Accelerated Integrated Programme 5 (AiP5) drive to lift capacity to 5 million b/d by 2027.

    Adnoc Onshore issued the main tender for engineering, procurement and construction (EPC) works on 19 June. Contractors submitted technical bids by 5 August, sources told MEED.

    The on-plot works include adding a crude processing train, produced water treatment and reinjection systems, surface water pumps, and multi-stage gas compression and dehydration units. Works also include utilities, safety and control systems, modifications to existing Phase 1 units and 220kV power infrastructure.

    The off-plot scope includes installing and tying in new gas-lifted producer and water-injection wells, as well as building and expanding wellhead clusters. Contractors will also lay crude-gathering, water-injection and gas-export pipelines connecting to the Adnoc Gas network and extend 33kV overhead power lines across the fields.

    The tender follows Adnoc Onshore’s shift in strategy for the wider North East Bab development – comprising the Al-Nouf, Rumaitha and Shanayel fields – after scrapping an earlier engineering, procurement and construction management (EPCm) approach. MEED reported in December that the operator had cancelled an off-plot EPCm contract awarded to China Petroleum Engineering & Construction Corporation (CPECC) in October 2024. Adnoc later cancelled a separate on-plot EPCm tender that it received bids for in the second quarter of 2025.

    In addition to the North East cluster, Adnoc Onshore continues to make progress on EPC works for another similar project to build off-plot facilities at the South East cluster of oil fields in Abu Dhabi, which is also integral to Adnoc Group’s AiP5 campaign.

    The South East cluster comprises the Asab, Mender, Qusahwira, Sahil and Shah fields and accounts for approximately a third of Adnoc Onshore’s oil production capacity.

    MEED previously reported that Adnoc Onshore awarded CPECC the EPC works for the South East off-plot facilities project, with the contract value estimated at around $1.2bn.

    CPECC is also performing EPC works on the South East on-plot facilities project in a consortium with Greece-headquartered Archirodon. Adnoc Onshore awarded an estimated $1.5bn contract for that project to the consortium in December 2024, with EPC works scheduled for completion in 2027.
