Organic Facies,rocks. Preservation of organic material is actually a rare event. Most organic carbon is returned to the atmosphere through the.(fig. 2.1); less than 1% of the annual photo- synthetic production escapes from the carbon cycle and is preserved in sediments. Oxidative decay of dead organic matter is a

Organic Chemistry and Isotopes,the names of common compounds and with several different conventions for drawing their structures. This objective is very different from that of a normal course in organic chemistry, in which one must also learn all the reactions of many classes of compounds. The chemical reactions of interest to us

Bitumen, Petroleum, and Natural Gas,ferences. There is no doubt that they are related; indeed, bitumen is almost universally accepted as the direct precursor for petroleum. However, many unanswered questions remain about the processes that transform bitumen into petroleum. Major compositional changes occur in going from bitumen to pet

Migration,ine-grained, low-permeability source rock into a carrier bed having much greater permeability..is the movement of oil and gas within this carrier bed..is the concentration of migrated hydrocarbons in a relatively immobile configuration, where they can be preserved over long periods of time..are the

Analytical Techniques,critical to our ability to describe the chemical composition of fossil fuels and kerogens, to predict source potential of sedimentary rocks, to correlate samples with each other, and to understand transformation processes like biodegradation. Without these sophisticated analytical capabilities, petr

Predicting Thermal Maturity,sample location. In most cases, however, measured maturity data are of limited value in exploration. Part of this problem is a consequence of the limitations we face in attempting to obtain reliable maturity measurements. In some areas there are no well samples available; indeed, in frontier basins

Correlations,on origin. We therefore frequently attempt to correlate samples by comparing their chemical and physical properties. Correlations are easiest between materials of the same type (two oils, for example), but they are also possible between dissimilar samples (oils with kerogens or bitumens, bitumens wi

Surface Prospecting, the naked eye, small, slow microseepages can only be detected with sensitive instruments. Many obvious seeps were used in the early days of the petroleum industry as important aids to exploration. More recently, however, interest has focused on locating and utilizing minor seepages of hydrocarbons.
