The Erawin onshore oil field is located in the Murzuq basin of Libya in North Africa. Zallaf Libya Oil & Gas Exploration and Production, a subsidiary of National Oil, owns the project.
Zallaf commenced operations at the Erawin oil field in March 2023 with a production capacity of 3,000 barrels per day (bpd).
Oil production from the field is expected to reach more than 16,000bpd once all the wells and pipelines linking the Erawin field to the Sharara field are ready. The Sharara field is operated by Akakus Oil Operations, one of the largest oil companies in Libya.
The start of operations at the Erawin field falls in line with NOC’s goal of reaching production rates of approximately two million bpd in the future.
Erawin field location
The Erawin field is located in the Murzuq basin within block NC200, covering a total area of 8,285km². It is 100km southwest of the El Sharara field (NC-115B) and 40km northeast of the city of Owainat.
Discovery and appraisal
Several exploration wells were drilled in the Murzuq basin by the previous operator, which led to three oil discoveries in the Mamuniyat formation (Ordovician Age) named E1, G1 and H1-NC200, of which the H1-NC200 discovery is now known as Erawin Field.
3D seismic data of approximately 478km² was acquired over the Erawin Field. Zallaf is drilling several development wells in the E Pool in the basin.
Erawin field details
The initial production at Erawin field is from four production wells: E-1, E4, E5, and E-7.
Approximately 10,000 barrels of crude oil produced from the Erawin field will be transported by pipeline over approximately 100km to the storage tanks in the Akakus oil operation located in the Sahara field. From there, pipelines will carry the oil to the Zawia oil refinery operated by NOC’s subsidiary, Zawia Oil Refining.
Tanker trucks will transfer the crude oil produced from the field to the surface treatment unit in the Sharara field (NC-115B).
The initial plan involves 12 tanker trips a day to transfer oil from production tanks at Erawin field to the treatment unit in Sharara field. The process will continue until the processing plant at Erawin is completed, including the installation of the pipeline linking Erawin and the Sharara field.
An airstrip was also constructed within the Erawin field to facilitate the installation of surface equipment and the export pipeline, and to alleviate logistic difficulties.
Zallaf awarded the engineering, procurement, construction and commissioning contract for the phase one development, which includes early production facilities, to Petrofac in September 2021.
The scope of work under the contract included surface equipment comprising well pads and flowlines at the Erawin field. The contract also involved the construction of a 100km pipeline to transport crude oil to the El Sharara oil field, including the installation of a control room, substation and telecom system for the El Sharara field.
Fayad Burgan supplied rigs for the project’s drilling and well maintenance activities through the National Drilling Company.
