A large number of theories proposed in the past to make clear the origin of petroleum are classified into two major concepts : inorganic and organic (biogenic) origin. Until the early years of this century, the inorganic origin has been lasted by many advocators. In recent years, kerogen becomes to be widely accepted as a petroleum origin. Hydrocarbon starts to be generated, at first gradually, then rapidly, by thermal cracking of kerogen with increasing depth of burial. This concept was proposed, at first by ABELSON (1963) and was advocated by COOPER et al. (1963), PHILIPPI, (1965), TISSOT et al. (1971) and the other researchers on reliable evidences. Prompting by their geochemical studies on organic matter in the sedimentary rocks in petroliferous areas, many strong geological evidences which are profitable for this concept have been introduced one after another.<BR>In this general review, the history of the theory on origin of petroleum, geological evidences which are profitable for the kerogen concept, relationship between diagenesis of the sedimented organic matter and petroleum generation, and time-temperature relation in petroleum generation are presented. There is still contraversy on the theory of the primary migration. The deposit of petroleum is formed through three processes : generation, migration and accumulation. The concept of petroleum origin must not be, therefore, inconsistent with those of the other processes. The study on kerogen itself is undoubtedly important and moreover to search an evidence of direct relation between source rock and petroleum accumulation is expected in the future.
