consumption with about 10,000 gas stations (as of 2005). Naftec, a subsidiary of Sonatrach, operates Algeria's four refineries, which have combined capacity of . The Skikda refinery (300,000 bpd) provides the bulk of Algeria's refined products production. The Hassi Messaoud refinery supplies products to southern Algeria, while the Algiers refinery processes crude from Hassi Messaoud for consumption in the capital. Finally, the coastal Arzew refinery produces products for domestic consumption and export. In July 2006, Sonatrach and the China National Petroleum Corporation (CNPC) brought online the small-13,000 bpd Adrar refinery, which is located near the village of Sbaa north of Adrar. On July 1, 2018, Sonatrach appointed Youcef Ghazli to head the Foreign Investment Division, which oversees all investments in Europe. In March 2022, Naftal officials signed a US$364 million engineering, procurement and construction (EPC) contract with Sonatrach's pipeline unit TRC. The pipeline should only take about 48 months to construct, and it would run 424 km from Arzew to Chlef, carrying about 1.2 million tonnes of LPG a year. Tassili Airlines A joint venture between Air Algérie (49%) and Sonatrach (51%) in 1998 established the passenger airline company Tassili Airlines. Commercial services were launched on 8 April 1999 with a flight from Hassi Messaoud to Algiers. In 2005, Air Algérie withdrew its funds in the airline, which thus became wholly owned by Sonatrach. In 2006, Sonatrach gave Tassili Airlines permission to expand its domestic destinations and for the future opening of international routes. Eni In July 2020, Sonatrach signed a contract with Italian company Eni. The contract which will run until 2049, includes the production marketing from three gas fields located in the south-east of the country. The three fields are Sif Fatima II, Zemlet El Arbi and Ourhoud II. An additional memorandum of understanding (MoU) was signed in December 2020 in order to boost exploration and production, as well as implement training activities. In March 2021, a new MoU was signed between the companies to focus on renewable energy, biofuels and hydrogen sectors. Various other agreements were also signed to cover exploration and production, research and development, decarbonization and training, and to strengthen the two companies' partnership. In April 2022, the CEOs of Sonatrach, Touffik Hakkar, and Eni, Claudio Descalzi, signed a contract to increase gas supplies to Italy through the Trans-Mediterranean Pipeline. Beginning in 2022, supply should increase gradually to 9 billion cubic meters per year in
