Generation and Migration of Light Hydrocarbons
Science, 1984Light hydrocarbons (containing from 1 to 14 carbon atoms) are formed from disseminated organic matter in sediments at the parts-per-billion level by biological and low-temperature (< 50°C) chemical reactions and at the parts-permillion level by high-temperature (> 50°C) cracking reactions. The cooler reactions produce mainly branched

Generation of hydrocarbons in source rocks
Naturwissenschaften, 1983Generation of hydrocarbons in source rocks is controlled by their temperature history with burial, as well as by quantity, type and structure of their kerogens. The degree to which hydrocarbon generation processes have advanced in a given source rock can be recognized on the basis of elemental analysis of kerogens (H/C-O/C diagrams), as well as by ...

Science in China Series D: Earth Sciences, 1997
The diagenetic mechanism and process of carbonate rocks, which is different to that of clastic rocks, decides the existence of different existing state organic matters in carbonate rocks. This has been verified by both the microscopic observation of organic petrology and the analysis of organic geochemistry of many samples.

An Algorithm to generate the compact name of benzenoid hydrocarbons
Computers & Chemistry, 1985Abstract A computer program that facilitates handling of the new compact nomenclature of condensed benzenoid hydrocarbons is presented. It allows derivation of the hydrocarbon name from the Cartesian coordinates of the carbon atoms. The program also provides a user with the possibility of verification of trial hydrocarbon names according to the rules

Basin Evolution and Hydrocarbon Generation
Geological Society, London, Special Publications, 1983Extended Summary It is now widely believed that sedimentary basins are formed by one of two processes: extension of the continental lithosphere, followed by subsidence (McKenzie 1978a); or flexure due to a load superimposed by thrusting (Beaumont 1981; Jordon 1981). Only basins formed by extension will be considered.

Petroleum Hydrocarbons: Generation from Fatty Acid
Science, 1964In the presence or absence of water, behenic acid generates hydrocarbons during heating at 200°C with bentonite. Without water the ratio of isobutane or isopentane to normal butane or normal pentane is much higher than with water. Besides C 21 and lower n-alkanes, n-alkanes with 22 to 34 carbon atoms are also formed.

Optimizing hydrocarbon generation calculations
Computers & Geosciences, 1996Abstract Modern simulations of hydrocarbon generation are complex and intractable analytically. Commercial software for solving nonlinear systems seldom yields sufficient accuracy by modern standards. Specially written software tends to be slow. All methods must cope with reaction rate constants that change rapidly as temperature or pressure varies ...

HYDROCARBON GENERATION IN THE NORTHERN PERTH BASIN
The APEA Journal, 1983All known commercial hydrocarbon accumulatios in the Perth Basin, Western Australia, occur within the Dandaragan Trough or along its flanks. Land plant-rich source rocks are widely distributed throughout the Permian, Triassic and Jurassic sections of the basin.

An isotopic study of hydrocarbon generation processes
Organic Geochemistry, 1985Abstract The sources of reservoired liquid hydrocarbons in Australia differ substantially from their Northern Hemisphere counterparts. Not only are Australian source rocks largely of terrigenous origin but the concepts accepted as defining the hydrocarbon potential of source rocks have recently been challenged.

High harmonic generation spectroscopy of hydrocarbons
Applied Physics Letters, 2010We have demonstrated the ability of few-cycle midinfrared intense laser pulses to produce extended harmonic spectra (≥45 eV) suitable for high harmonic spectroscopy in aligned hydrocarbons with ionization potentials in the range 9.07–11.52 eV. Modulations in the spectra measured with different alignment angles show signatures of the molecular structure.
