Petroleum deposits form as a consequence of the increased temperatures that accompany
progressive burial of organic matter deep within sedimentary basins. Recent advances in …

As geochemical appraisals of mineral regions of commercial prospectivity evolve, the
organic matter associated with metal rich ores has attracted greater attention. Petroleum …

Pyrolysis experiments were conducted on immature petroleum source rocks under various
conditions to evaluate the role of water in petroleum formation. At temperatures less than …

Immature source rock chips containing different types of kerogen (I, II, IIS, III) were artificially
matured in isotopically distinct waters by hydrous pyrolysis and by pyrolysis in supercritical …

FTIR absorbance signals in kerogens and macerals were evaluated as indices for thermal
maturity. Two sets of naturally matured type-II kerogens from the New Albany Shale (Illinois …

Organic matter, water, and minerals coexist at elevated temperatures and pressures in
sedimentary basins and participate in a wide range of geochemical processes that includes …

Vacuum residue (VR) upgrading was conducted in the environment of supercritical water
(SCW) without oxygen addition in an attempt to yield a maximum of light oil. Simulated …

Internationally distributed organic and inorganic oxygen isotopic reference materials have
been calibrated by six laboratories carrying out more than 5300 measurements using a …
