The Erawin Field Development Project is an onshore oil field located in the Murzuq Basin in southwest Libya.

Zallaf Libya Oil and Gas Exploration and Production Company, a 100% subsidiary of the National Oil Corporation, is the owner of the project.

The preparations and procedural works at the project’s site to commence the operations of developing the field began in 2019.

In January 2021, Zallaf announced the official start of drilling operations at Erawin Field.

The field commenced production operations within the alternative plan, Early Production (EPF) in March 2023.

Initially, the onshore field will produce 3,000 barrels per day (bpd) of crude oil.

Once all wells and pipelines linking the Erawin and Sharara fields are ready, the production rate is expected to cross 16,000bpd.

Production from Erawin will help the National Oil Corporation to achieve its goal of reaching production rates of approximately 2 million bpd (mbpd) in future.

Location details

The Erawin Field Development Project is located in Murzuq Basin spreading over an area of 8,285km2.

The previous operator had drilled several exploration wells in the region that resulted in three oil discoveries from the Mamuniyat formation (Ordovician Age), namely- E1, G1 and H1-NC200. This is known as Erawin Field.

The field lies in block NC 200 around 100km southwest of the El Sharara Field and approximately 50km northeast of Alawainat.

Around 478km2 of 3D seismic data was acquired over the field.

Erawin Field details

Zallaf initially focussed on developing the E Pool by drilling multiple development wells.

The development includes wells, well flow lines, power and automatic control cables for connecting with the station of NC-115B, pipeline storage yard, and an early production station.

In 2021, Zallaf conducted tests on E-4 well by using Closed Loop System.

Under the system, the extracted oil does not get burnt preventing air pollution and depletion of natural resources.

Erawin Field will transfer crude oil produced via tankers from the production tanks to the surface treatment unit in the Sharara Field (NC-115B) operated by Akakus Oil Operations.

Initially, the tankers will make 12 trips per day to transport the produced crude to the treatment unit. Eventually, crude oil from Erawin will to be transported Sharara field through a 100km long pipeline.

Zallaf had also constructed an airstrip to minimise logistical difficulties and facilitate the installation operations for surface equipment and the exporting pipeline in the Erawin field.

The site was brought under the coverage of the Almadar Mobile Network in March 2022 to offer all services and capabilities to the company’s users in the Erwin field and the surrounding areas.

A solar energy system was also installed to provide logistical support for Erawin oil field development.

Contractors involved

The Front-End Engineering and Design (FEED) contract for the Erawin Field Development Project was awarded to Worley. The engineering studies commenced in July 2019.

In September 2021, Zallaf awarded the Engineering, Procurement, Construction, and Commissioning (EPCC) contract for the project’s Phase 1 Early Production Facilities to Petrofac. The contract was valued more than $100m.

The EPCC scope of the contract included surface equipment including well pads and flowlines, as well as a pipeline for transporting crude oil to the El Sharara Field, and substation, a control room, and telecom system.

The National Company for Drilling and Maintenance of Oil Wells was one of the contractors of the onshore oil project.

Other contractors included Al-Jouf Oil Technology Company, Adaam Holding Company, Ser Alebdda, Schlumberger, SGS, Camco, and Nesr.

Fayad Burgan Company supplied the rig for the project through the National Drilling Company. The MV CLIPPER ship transported the crude oil pipelines from Tianjin Port in China to Alkhoms Port.
