Physicochemical and Genetic Study of the Crude oils of Different Basins
I.P. Pandey | Harish Chandra Joshi
Abstract: Petroleum is a mixture dominantly of hydrocarbons with varying proportions of non-hydrocarbon constituents and traces of organometallic compounds. Generally Petroleum has an average composition of 85% carbon, 13% hydrogen, and 2% of sulphur, nitrogen and oxygen. Organic geochemistry can be defined as the study of the fate and distribution of carbon compounds in contemporary environments, in Recent and ancient sediments. 'Biological marker' or shortened to 'Biomarkers' or Geochemical Fossils are complex molecules derived from once living organisms they are found in sediments and oil and show little change in structure from their parent molecules. Genetic correlation of petroleum is important to identify source rocks and determines the migration pathways. It is based on the concept that the composition of the organic components in a source rock is transmitted to the oil. The aim of study is to find out the physicochemical and genetic property of petroleum. The Crude oil was collected from different basins of India. To avoid the loss of lighter hydrocarbon preserve the sample. The sample will be fractionated and different fraction will be obtained with the help of HPLC and GC-MS. In this process different Biomarker were obtained which are then expelled to migrate along carrier beds and other conduits to traps.
