Background
Discovered in 1956, Zelten was Libya's first major oil well, producing about 17,500 bbl/d (2,780 m3/d). In 1959, its reserves were estimated at 2.5 billion barrels (400,000,000 m3) of 38° API oil, lying at 5,500-7,600 feet. Esso Standard began production of Zelten in 1961. The Zelten gas-lift system was installed during the period from 1969 to 1971 and represented one of the first uses of gas lift on a fieldwide basis to produce the high volume wells typical of Middle East Oil fields. In 1979, approximately 500,000 bbl/d (79,000 m3/d) of total liquid was being produced by gas lift. By 2006, the accumulated production of the Zelten field reached 2,426 mmb of oil and 1,506×109 cu ft (4.26×1010 m3) of associated gas.

Famous quotes containing the word background:
“Silence is the universal refuge, the sequel to all dull discourses and all foolish acts, a balm to our every chagrin, as welcome after satiety as after disappointment; that background which the painter may not daub, be he master or bungler, and which, however awkward a figure we may have made in the foreground, remains ever our inviolable asylum, where no indignity can assail, no personality can disturb us.”
—Henry David Thoreau (1817–1862)
“Pilate with his question “What is truth?” is gladly trotted out these days as an advocate of Christ, so as to arouse the suspicion that everything known and knowable is an illusion and to erect the cross upon that gruesome background of the impossibility of knowledge.”
—Friedrich Nietzsche (1844–1900)
“In the true sense one’s native land, with its background of tradition, early impressions, reminiscences and other things dear to one, is not enough to make sensitive human beings feel at home.”
—Emma Goldman (1869–1940)
