Tongwei Zhang, Alon Amrani, Geoffrey S Ellis, Qisheng Ma, Yongchun Tang, David Applegate
2008, Geochimica et Cosmochimica Acta (72) 3518-3530
Hydrogen sulfide (H2S) is known to catalyze thermochemical sulfate reduction (TSR) by hydrocarbons (HC), but the reaction mechanism remains unclear. To understand the mechanism of this catalytic reaction, a series of isothermal gold-tube hydrous pyrolysis experiments were conducted at 330 °C for 24 h under a constant confining pressure of 24.1 MPa. The...
Theoretical study on the reactivity of sulfate species with hydrocarbons
Qisheng Ma, Geoffrey S Ellis, Alon Amrani, Tongwei Zhang, Yongchun Tang
2008, Geochimica et Cosmochimica Acta (72) 4565-4576
The abiotic, thermochemically controlled reduction of sulfate to hydrogen sulfide coupled with the oxidation of hydrocarbons, is termed thermochemical sulfate reduction (TSR), and is an important alteration process that affects petroleum accumulations in nature. Although TSR is commonly observed in high-temperature carbonate reservoirs, it has proven difficult to simulate in...
Estimation of the change in freshwater volume in the North Coast Limestone upper aquifer of Puerto Rico in the Rio Grande de Manati-Rio de la Plata area between 1960 and 1990 and Implications on public-supply water availability
Fernando Gómez-Gómez
2008, Scientific Investigations Report 2007-5194
Ground water in the upper aquifer of the North Coast Limestone aquifer system historically has been the principal source of public-supply and self-supplied industrial water use in north-central Puerto Rico. Development of the aquifer for these two major water-use categories began in about 1930; however, withdrawals did not become an...
