Other major fields operated by Sonatrach include Tin Fouye Tabankort Ordo,[9] Zarzaitine,[10] Haoud Berkaoui/Ben Kahla,[11] and Ait Kheir.

Sonatrach gained control over all Algerian petrochemical resources following President Houari Boumedienne's nationalisation of all French oil and gas holdings beginning on February 24, 1971.

Beginning on December 10, 1979, a conference on the exploitation of petroleum recommended increasing participation in the research efforts by foreign companies and countries.

The Sonatrach-Gaz de France accord, signed on January 12, 1989, allowed the state to set a compromise price of about $2.30 per million BTUs.

A total of 9.5 billion cubic meters of natural gas were delivered annually until 1990, and Sonatrach recovered 850 million francs in arrears, since the accord applied retroactively beginning on November 1, 1987.

[17] On 22 July 2019, the Sonatrach-controlled oil tanker Mesdar was briefly detained as it transited the Straits of Hormuz by the Islamic Republic of Iran.

[18] In November 2021, Sonatrach announced that it would be carrying out the development of a 10 MWp photovoltaic plant in the basin of Hassi Berkine in order to supply oil sites within the region.

[19] Sonatrach signed a US$179 million contract on 17 February 2022 with Sinopec from China, to construct an LNG storage tank which will hold 150,000m3 at the Skikda gas export terminal.

[20] With the Russian invasion of Ukraine, Sonatrach CEO Hakkar stated in February 2022, that the company would be willing to supply Europe with more gas, however only the unused capacities in the Trans-Mediterranean Pipeline (Transmed) could be transferred to the European market.

[22] In March 2022, Sonatrach and Eni made a major discovery of oil and gas in the Zemlet el Arbi concession, as the HDLE-1 well was drilled, one of five to be placed in the Berkine North basin.

[23][24] Eni and Sonatrach signed an agreement in April 2022 to increase the amount of gas imported to Italy through the TransMed / Enrico Mattei pipeline to up to 9 billion cubic meters per year by 2023/24.

[25][26] It was confirmed in June 2022 from PTT Exploration and Production (PTTEP) that the Hassi Bir Rekaiz had hit first oil, they have 49% stake in the project, where as Sonatrach holds the other 51%.

[27] In July 2022, Sonatrach and its partners announced a production sharing contract (PSC) which will invest a total of $4 billion over the course of 25 years into onshore blocks located in the prolific Berkine basin.

[31][32] Multiple oil and gas discoveries were made in the summer of 2022 including one that is close to the Hassi R'Mel field,[33] two were found during exploration in the Ekker Sud West-1 well, and there were positive results during drilling in the Tamzaia-3.

With the increase in Algeria's role as supplier and trying to recover the loses from previous years, considerate price reviews were being made for each company in which they supply too.

Algeria faced declines in the energy sector for the last decade but due to the Russian invasion of Ukraine and new investment laws, they have recovered in the last year becoming the biggest gas supplier to Italy.

The original contracts were converted to comply with Algeria's 2019 petroleum law, and the companies agreed to upgrade the facilities already in place and increase production by drilling additional wells.

[47] The complex is made up of 37 wells which are connected to the gas processing facility leading though the pipelines to Hassi R’mel and TotalEnergies has been managing it since 2018.

[47] In May 2024, Sonatrach signed an agreement with ExxonMobil to study existing opportunities for developing hydrocarbon resources in Ahnet and Gourara basins in Southern Algeria.

In March 2022, Naftal officials signed a US$364 million engineering, procurement and construction (EPC) contract with Sonatrach's pipeline unit TRC.

[53] An additional memorandum of understanding (MoU) was signed in December 2020 in order to boost exploration and production, as well as implement training activities.

[56] 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.

The U.S. Energy Information Administration reported that in 2005, Algeria had 160 trillion cubic feet (Tcf) of proven natural gas reserves, the eighth largest in the world.

[64] In May 2020, an arrest warrant was issued against a representative of Sonatrach in Lebanon, as part of a greater operation against embezzlement of public funds in contribution with Lebanese officials.

[65] Abdelmoumen Ould Kaddour, who was chief executive of Sonatrach from March 2017 to April 2019, was arrested in February 2021, and in August of that year he was extradited from the United Arab Emirates, all related to his alleged involvement in various corruption cases.
