Since 1959, more than 114 oil and gas fields estimated to contain more than 4 billion tons (28 billion bbl) have been discovered in the W. Siberian Lowland, a topographic and structural basin east of the Ural Mt. All fields discovered to 1970 are on anticlinal structures, found mainly by geophysical work, including magnetic, gravity, and seismic profiling. Detailed seismic work was begun in 1964. Producing structures consist of irregularly shaped areas of closure on large anticlinal arches. Most fields are medium size, covering less than 100 sq km (25,000 acres), and contain less than 30 m (100 ft) of pay sandstone. Average depth of the wells is 2,500 m (8,000 ft). Several pools are large in area, but medium size in reserves. A few pools contain over 300 million tons (2.1 billion bbl), of which the largest is Samotlor with slightly more than 2.5 billion tons (15.1 billion bbl). Halbouty et al. included 8 other W. Siberian fields among the giant oil fields of the world. Several large gas fields have been discovered in the N. part of the basin, with proved reserves of 9 trillion cu m (315 trillion cu ft).
