Exploration and development activity is focused in the Bir Rebaa desert, located in the central-eastern part of the country, in blocks 403a/d (Eni 65%-100%), North ROM (Eni 35%), 401a/402a (Eni 55%), 403 (Eni 50%), 405b (Eni 75%) and 212 (Eni 22.38%). In the North Berkine basin, Eni's activities are concentrated in the Sif Fatima II, Zemlet El Arbi and Ourhoud II blocks, where we are 49% operators. We also hold 12.25% in the non-operated blocks 404 and 208. Our Algerian exploration and production operations are regulated by Production Sharing Agreement (PSA) concession contracts. In July 2018 Eni and Sonatrach agreed the extension of block 403, the agreement also includes the construction of a pipeline to connect BRN's assets with MLE with the aim of creating a gas hub. In the Sif Fatima II, Zemlet El Arbi and Ourhoud II concessions in the North Berkine Basin, the accelerated development of the estimated 75 million boe of reserves owned by Eni and an exploration campaign are underway. The oil wells were started up in May 2019. The production of gas fields will start at the same time as the start of the BRN-MLE pipeline. In December 2018, the consortium formed by Sonatrach, Eni and Total was granted two exploration permits to carry out seismic acquisition activities in the Algerian offshore sector. We are operators of the permit to the east called Skikda where in the spring of 2019 we acquired about 2,000 km2 of 3D seismic and 200 km2 of 2D seismic.
In March 2020 we completed the construction of the gas pipeline connecting Bir Rebaa Nord (BRN) and Menzel Ledjmet Est (MLE) fields in the Berkine Basin, in the south-eastern part of Algeria. The project will allow for the export of the associated gas produced in Block 403 (BRN and BRSW) and the development of the gas fields of the blocks of North Berkine.
