... (UBS) in the Williston Basin is a world class source rock with an average TOC of 11.5 wt and also, a resource play with a history of oil production in the 1990s. Previous studies have suggested that the main reason behind the organic enrichment in UBS is the enhanced preservation potential of organic...

...) Play (Neuquén Basin, Argentina) focusing on an oil window mature well (VR ~0.9-1.1%) to determine 1) zones of enrichment and depletion, 2) correlation/allocation to produced fluids, and 3) in-situ GOR and PVT characteristics. Zones of saturation versus depletion, total in-place liquids, oil quality...

... material. The authigenic enrichment in elements typical for anoxia and elevated palaeoproductivity (Ni, Cr, V, Cu, Mo, U) was revealed to be inconsistent throughout the shale sequence, with the major change in the trace element - Total Organic Carbon (TOC) correlation trends at TOC ca. 2%. For organic...

... response actually falls within the Utica Shale. Gamma-ray response principally reflects the abundance of K, Th, and especially U. Indeed, it is enrichment of the latter above crustal levels in the presence of abundant organic matter and related bacterial sulfate reduction typical of those environments...

... Atascosa, Bee, DeWitt, Karnes, La Salle, Lavaca and Live Oak counties. In addition, using the enrichment or depletion of minor and trace elements relative to their crustal abundances, anoxic or oxic conditions may be inferred. These data, especially when incorporated with biostratigraphy, result...

The distribution patterns of REEs in the organic materials normalized to PAAS (post-Archean Australian Shale) had the following significant features: all but one out of the ten samples had a La-Lu trend with HREE enrichment in general, by an amount as much as 15%, all had both Ho and Tm...
