Production
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.
