Petroleum Alteration

Abstract

Petroleum is a very complex mixture of organic compounds and has a high energy content; it is thermodynamically metastable under geological conditions. Petroleum after being pooled in a reservoir is therefore susceptible to alteration. Attention to the importance of alteration was directed by a number of papers (Williams and Winters, 1969; Evans et al., 1971; Bailey et al., 1973a), which investigated heavier crude oils of Western Canada.
