tabankort ordo sonatrach notes 1 . eia 2007 . history edit sonatrach was founded on december 31 1963 . at the time however the algerian state held only 4.5 % of the exploration perimeters while french interests were as high as 67.5 % . 3 after the arab israeli war in june 1967 algeria decided to nationalize the refining and distribution activities of mobil and esso and sonatrach signed an agreement with getty oil on october 19 1968 receiving 51 % of getty oil s interests . it 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 . the old concession system was replaced by a seizure of a 51 % share of french petroleum companies . only total agreed to continue its activities ; the other companies left algeria . beginning on december 10 1979 a conference on the exploitation of petroleum recommended increasing participation in the research efforts by foreign companies and countries . by a decree published in the journal officiel on may 17 1980 sonatrach was divided into four enterprises . from 1986 it became possible for foreign hydrocarbon companies to do business in algeria within a partnership with sonatrach this process was simplified in 1991 . 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 . in march 2005 the algerian parliament adopted the hydrocarbon reform bill encouraging international oil company ioc investment in the hydrocarbon sector which sonatrach previously dominated . however 2006 amendments to the hydrocarbon bill created a windfall tax on ioc profits when oil prices top 30 per barrel . this tax reached up to 50 % on some contracts . in addition the amendments gave sonatrach rights to a 51 % or higher participation option on each newly discovered project . 4 subsidiaries and joint ventures edit a naftal gas pump sonatrach owns 50 % of numhyd a joint venture with tunisia s etap and alepco a joint venture with libya s national oil corporation . in 1998 sonatrach acquired naftal which is the principal company selling petroleum based fuels for domestic 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 450 000 bbl d 72 000 m3 d . the skikda refinery 300 000 bpd provides the bulk of algeria s refined products production . the 30 000 bbl d 4 800 m3 d hassi messaoud refinery supplies products to southern algeria while the 60 000 bbl d 9 500 m3 d algiers refinery processes crude from hassi messaoud for consumption in the capital . finally the coastal 60 000 bbl d 9 500 m3 d 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 40 km 25 mi north of adrar . 4 algerian hydrocarbon sector edit hydrocarbons play a crucial role in algeria s economy accounting for roughly 60 % of budget revenues and over 95 % of export earnings . the country ranks fourteenth in petroleum reserves containing 11.8 billion barrels 1.88 109 m3 of proven oil reserves with estimates suggesting that the actual amount is even more . 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 . 5 as a result sonatrach is very important politically . most energy ministers of algeria have come from a sonatrach background . tassili airlines edit a joint venture between air alg rie 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 alg rie 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 .
