Geochemistry of oil seepages and Paleocene organic-rich shale deposits from the onshore East Coast Basin in New Zealand: implications for characteristics, origin and oil-source rock correlation

Journal of Petroleum Exploration and Production Technology
In this study, four oil seepages and ten organic-rich shale samples of the Paleocene Waipawa Formation from outcrop sections in East Coast Basin, New Zealand were studied.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Experimental study on the long-term conductivity of self-support fracture in deep shale reservoirs

Journal of Petroleum Exploration and Production Technology
Reservoir modification fracturing technology is one of the key technologies for the effective development of deep shale gas reservoirs. But the low initial production and fast decreasing after fracturing deep shale gas wells restrict the efficient ...

Experimental Study on Mechanical Properties of Rock in Water-Sensitive Oil and Gas Reservoirs Under High Confining Pressure

Applied Sciences
Injecting high-pressure fluid into a reservoir rock mass will change the mechanical properties of the rock; the strength and safety of a shale well wall are also extremely critical.

On the theory of solitons of fluid pressure and solute density in geologic porous media, with applications to shale, clay and sandstone

, 2016
In this paper we propose the application of a new model of transients of pore pressure p and solute density \r{ho} in geologic porous media. This model is rooted in the non-linear waves theory, the focus of which is advection and effect of large pressure

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...
