Petroleum Geology of the South Caspian Basin

L. Buryakovsky, Fred Aminzadeh, G.V. Chilingarian9780884153429, 0-88415-342-8

In this information-packed volume, the authors present mathematical models and analyses for evaluating, assessing, and describing the petroleum geology of the oil-rich South Caspian Sea Basin, including eastern Azerbaijan and western Turkmenistan. Their mathematical models include descriptions of the development and structure of the surrounding geological systems and traps.
