Three key oil and gas projects in Libya have seen developments amid an uptick of activity in the North African country’s hydrocarbon sector.

The contract scopes include seismic work, the development of subsea pipelines, and drilling services.

An invitation to prequalify has been issued for a project to provide two-dimensional (2D) and three-dimensional (3D) offshore seismic surveying services.

The zone to be surveyed is known as the Libyan Offshore Area O1, and is located in the Sirte Basin.

The winner of the contract will be responsible for:

• Acquisition of approximately 6,100 km² of 3D full-fold marine seismic data
• Acquisition of approximately 3,000 km of 2D full-fold marine seismic data

The client on the project is the Italian oil and gas company Eni.

In a statement posted on the website of Libya’s National Oil Corporation (NOC), it said: “The objective of the survey is to acquire, within the required operational window from September 2027 to March 2028, high-quality broadband seismic data to improve the imaging of Cretaceous reservoir sequences and support future exploration activities.”

The deadline for the submission of prequalification documents is 2 December 2026.

Deadline extended

Libya’s Mellitah Oil & Gas Company (MOG) has extended the deadline for companies to submit prequalification documents for a major offshore package as part of its Mellitah Complex Expansion & CO2 Management Integrated Development Project, which is estimated to be worth about $8bn.

The previous deadline of 5 November 2026 has been replaced by a deadline of 3 December 2026.

Libya’s Mellitah Oil & Gas Company (MOG), a joint venture of Libya’s National Oil Corporation and Italian oil and gas company Eni, is the client on the project.

The package, known as WP4B1, focuses on developing offshore pipelines and subsea systems for the E offshore installation and CO2 project.

The turnkey contract will use the engineering, procurement, installation and commissioning (EPIC) model.

As part of the Mellitah complex expansion and CO2 management integrated development project, two offshore structures – Structure A and Structure E – will be developed in Libya’s offshore block NC 41.

Structure A is also known as wellhead production fixed platform A (WHPA) and Structure E is also known as production platform E (PPE).

Structure A is in the central-western part of the area, about 80 kilometres (km) from the Libyan coast, with a water depth of 95-105 metres.

Structure E is located in the central-eastern part of the area, about 130km from the Libyan coast, in a water depth of 205-235 metres.

The scope of the wider project includes:

• A new production platform installed in about 220 metres of water depth as part of the development of Structure E (Package WP1)
• A new wellhead platform installed in 96 metres of water as part of the development of Structure A (Package WP2)
• Modification of the existing Sabratha platform (Package WP3)
• Sealines and subsea systems extending from the Sabratha platform to Structure A (Package WP4A1)
• Sealines and subsea systems for Structure E and the CO2 system (Package WP4B1)
• Supply of seamless carbon steel pipes for CO2 injection from the Mellitah complex to Sabratha platform (Package WP4B2)
• Subsea Production Systems (SPS) for Structure E and CO2 (Package WP4B3)
• Upgrading the existing onshore Mellitah complex (WP5)

The package known as WP4B1 has been broken down into two phases.

The first phase focuses on the installation of the project’s subsea CO2 pipeline and its related system network.

The second phase of WP4B1 is focused on the pipeline to structure E and its related subsea system network.

Monitoring drilling

MOG has also issued a separate invitation for prequalification relating to a contract to provide hydrogen sulphide monitoring services for offshore drilling.

The contract is focused on providing the H2S monitoring services for 18 offshore development wells as part of the “Structures A&E” project.

Four of the wells will be subsea wet wells and a further 14 will be dry tree wells.

The deadline for the submission of prequalification documents is 3 December 2026.

The work will be carred out in the zone known as Area D, Block NC41.

H2S monitoring in the oil and gas industry involves tracking H2S gas concentrations in the air using electronic sensors and detectors to protect workers, prevent fatal exposures, and avoid equipment damage.
