The rationally structural engineering is an efficient strategy to improve the comprehensive performance of potassium-ion storage anode materials. In this paper, a hybrid with hollow FeS2 nanoparticles anchored into the 3D carbon skeleton (labeled as…
During geological CO2 storage traditionally CO2 is injected subsurface into a high permeability reservoir capped by a low permeability seal to trap the buoyant supercritical plume. Wastewater from oil and gas production is also currently disposed of…
Water (H2O) and minerals involved organic-inorganic reactions are critical for hydrocarbon evolution in sedimentary basins and deep in the Earth. The mechanism and isotope fractionation for H2O-mineral-hydrocarbon interactions remain unclear. In this…
Inorganic sulfur (S) species including pyrite (FeS2) and sulfates may co-exist with organic matter (OM) in source rocks. Their inter-related effects on hydrocarbon generation and decomposition, and the 34S isotope fractionation during thermal…
Gas shales contain a variety of clay-rich materials with multifarious pore networks. Clay-hosted porosity is an essential component and considered to play a crucial role in establishing the original hydrocarbon molecules in place and transport…
Shale samples of lacustrine Shahejie Formation from the Well F39X1 drilled in Qikou sag were used to study microstructures, mineralogy, and organic geochemistry and their impacts on oil storage response. Samples are quartz and clay rich and contain a…
The origin and potential source of the presalt natural gas in the Lower Paleozoic Ordovician carbonates within the Ordos Basin, China, is heavily debated, and the causes of carbon isotope reversal are currently unclear. This study analyzes the source…
As an enhanced oil recovery method, the air injection process (AIP) has been applied for decades. However, deviations are still being identified between laboratory tests and field applications. One possible reason for such deviations is the formation…
