[Libya] Western Libya Gas Pproject

Unread post by escveritas »

The Western Libyan Gas Project (WLGP) is a gas processing project in Libya promoted by the ENI Group of Italy and the Libyan state-owned oil company, the Libyan National Oil Corporation. The natural gas and NGL produced from the large-scale project is exported to Europe via overland and undersea pipelines. The project includes two plants, one located 600 km from Tripoli in the inland Wafa region, and the other located in the Mellitah region on the Mediterranean coast. JGC received the contract for this project in 2001, as part of a joint venture with Tecnimont (Italy) and Sofregaz (France). JGC took charge of the most upstream part of the project, the gas and NGL processing plant in the Wafa region. This was the first EPC (engineering, procurement and construction) project undertaken by a Japanese contractor in the interior part of Libya. Even given our long record of executing projects in remote areas, this project was located in one of the most remote areas we have ever worked in.

The inland desert region where the plant is situated could indeed be described as "a lonely inland island where even birds do not fly". Because transportation infrastructure in Libya is lacking throughout the entire country, the project began with the construction of a temporary shipping road. However, shipment of the necessary equipment to the project site still proved difficult. We also encountered numerous other difficulties, including the severity of the climate, and a ban on Asian workers entering the country following the outbreak of the SARS virus in Asia in 2003. However, JGC brought all our strengths to bear on effectively managing the complicated work schedule so as to minimize the delay.

Production

Mellitah Oil & Gas is The operator of western Libya gas project (WLGP), which entails the development of two reservoirs; Wafa field located in the south west part of Libya, adjacent to the Libyan-Algerian border Approximately 500 km from the Mediterranean coast, Bahr Essalam field located offshore and covering an area distant between 30 and 350 km from the Libyan coast in water depth ranging from 70 to 350 m.
The main target of the project is to annually produce (10) BCM of sales gas; (8) BCM for export to GELA-Italy through Green Stream 32’’ pipeline and (5) BCM for the local market.

Wafa field

Oil and gas field with a significant gas cap and limited quantity of recoverable oil; it is producing gas and associated condensate from the gas cap through (30) gas wells and oil with associated gas from oil zone through (21) oil wells.

The production from (51) wells collected in different gathering stations (NG1, NG2, SG1, NO1 & NO2) and routed for separation and treatment at the central plant.

The on specification gas is delivered to Mellitah by the 32’’ pipeline (527 km), the average gas delivery is about 13 MMSm3 /day.
The production of oil & condensate sent to storage tanks in Wafa field , and then delivered in mixed mode with NGL coming from gas trains to Wafa Coastal plant by 16’’ pipeline for more processing. Approximately 23 KBbls of NGL and 38 KBbls of oil & condensate are delivered daily to Mellitah.

Bahr Essalam field

Gas field where gas and associated condensate are produced from (26) wells; (15) platform wells and (11) sub-sea wells.

The production is gathered on the platform where the gas is primarily dehydrated and approximately 28.2 MSCM/D (995 MMSCF/day) of sour gas delivered to Mellitah gas Treatment plants for further treatment by 36’’ sea-line (110 km), the un-stabilized condensate is delivered to Mellitah fractionation and stabilization units for further processing by the 10’’sea-line for stabilization.

Mellitah Complex

Comprise of Wafa coastal plant, Mellitah plants and Marine export facilities.

Wafa Coastal plant

Treats production received from Wafa desert and includes; fractionation and stabilization units to produce oil and LPG; the oil is routed to storage tanks with total capacity of about 2.5 MBbls, and the LPG is routed to the LPG splitter to produce commercial Propane and Butane which finally routed to fully refrigerated storage tanks, Propane storage capacity is about 230 KBbls, Butane storage capacity is about 210 KBbls

Mellitah plant

treats production received from Bahr Essalam field and includes; gas Treatment Units (GTU), sulfur recovery units (SRU), fractionation units and condensate stabilization units.

Gas plant

The raw gas received from the Sabratha platform is treated in Mellitah gas Treatment Units to produce sales gas, the Mellitah plant sales gas combined with sales gas treated at wafa desert via Wafa coastal plant, then the total sales gas is delivered through fiscal metering to Mellitah gas compressor station ( MGCS ) for final export to Italy.

In addition the production of LPG (Propane, Butane) and stabilized condensate delivered to storage tanks with capacity of about 860 KBbls.

Sulfur RecoveryUunits (SRU)

Sulphur recovery units are designed to convert the H2S removed from the raw gas to elemental sulphur in a liquid form, which’s then sent to past illation unit for solidification and stored and exported as solid sulphur.

Storage capacity of liquid sulphur is about 17,000 Sm3, and the storage capacity of the solid sulphur is about 25, 000 tons.

Marine export facilities

• Marine loading facilities contains two single mooring point (SPM) for the export of oil and condensate, one (SPM) is dedicated for the export of oil received from El-Feel field and wafa field
• the jetty is equipped for the export of LPG and Solid Sulphur.

Bahr Essalam Phase 2 Development offshore project begins production

Phase 2 of the project completes the development of the largest producing offshore gas field in Libya, thereby extending the field's production life.
San Donato Milanese (Milan), 5 July 2018 – National Oil Corporation (NOC) and Eni announce that Mellitah Oil & Gas, Eni and NOC joint venture company (50/50), has started production from the first well of the offshore Bahr Essalam Phase 2 project. This comes just three years after the final investment decision. Two further wells will begin production within a week. An additional seven wells will come on-stream by October 2018.

Phase 2 of the project completes the development of the largest offshore producing gas field in Libya, increasing production potential by 400 million cubic feet of standard gas per day (MMSCFD). Phase 2 will be completed between September and October, bringing total field production to 1,100 MMSCFD. Bahr Essalam, located about 120 kilometres northwest of Tripoli, contains over 260 billion cubic meters of gas. This is delivered through the Sabratha platform to the Mellitah onshore treatment plant before principally being used to supply the national network.

Chairman of the Presidential Council of Libya and Prime Minister of the Government of the National Accord, Fayez Al-Saraj, attended the opening ceremony and thanked the workers of NOC, Eni and Mellitah Oil & Gas for their efforts in developing the Libyan oil & gas sector.

Mr Al-Saraj commented: “The opening of Phase 2 of the Bahr Essalam offshore project will definitely add true value to the national economy. In the past, we missed huge investment opportunities due to the lack of budget. However, today we are committed more than at anytime to encourage investment in the oil sector, and to grant promising opportunities to global giants on a commercial basis that serves the interest of this partnership, and creates growth that gives new hope to the Libyan youth. Therefore, efforts must be intensified by all parties to have a deeper understanding and be willing to compromise for the youth of this country who are the real stakeholders in its stability.”

NOC’s Chairman Eng. Mustafa Sanalla added: “NOC is committed to guaranteeing and increasing gas production in order to supply Libyan power plants. This will support the development of the domestic market and reduce costly liquid fuel imports. This strategy will free up significant financial resources; essential given the enormity of challenges across the country. Eni have demonstrated the confidence that international oil companies have in NOC, and the success that legitimate partnerships can deliver for all Libyans.

Eni's CEO Claudio Descalzi commented: "Bahr Essalam is the product of a longstanding relationship between NOC and Eni, and represents an important milestone to ensure greater energy supply security for Libya. The project further demonstrates the trust and recognition Eni has in NOC as Libya’s sole legitimate oil corporation; one with whom we will continue to work exclusively in-country.

"The start of production – delivered in an impressive time-to-market, and in a challenging environment - is a significant achievement for Mellitah Oil & Gas. We are proud that Phase 2 will play an important role in supplying Libya with the necessary gas to fuel the country's recovery over the next 15 years.”

Eni has been present in Libya since 1959, where it currently produces around 320,000 barrels of oil equivalent per day.
