Abstract Natural gas hydrate (NGH) has been widely considered as an alternative to conventional oil and resources in the future energy resource supply since Trofimuk’s first assessment 1973. At least 29 global estimates have published from various studies so far, among which 24 are greater than total resources. If drawn chronological order, historical show a clear downward trend, reflecting changes our perception with respect its potential increasing knowledge on NGH time. A time series of...
The Steptoean Positive Carbon Isotope Excursion Event (SPICE) represents one of the largest carbon cycle perturbations in Cambrian, which coincided with climatic changes and dramatic extinction shallow-shelf faunas. This perturbation has been linked to a global expansion marine euxinia (SPICE-OAE), but precise timing, duration extent changing redox conditions across SPICE event, as well its influences on coeval biotic evolution, remain unclear. Here, we report paired δ98Mo–δ238U data this...
Abstract The Cambrian is the most poorly dated period of past 541 million years. This hampers analysis profound environmental and biological changes that took place during this period. Astronomically forced climate cycles recognized in sediments anchored to radioisotopic ages provide a powerful geochronometer has fundamentally refined Mesozoic–Cenozoic time scales but not yet Palaeozoic. Here we report continuous astronomical signal detected as geochemical variations (1 mm resolution) late...
Continuous and biostratigraphically well-constrained carbon isotope (δ13Corg) profiles through the upper Miaolingian (middle Cambrian) to Tremadocian (Lower Ordovician) part of Alum Shale Formation in four drill cores from southernmost Scandinavia are described. The sections record seven Furongian (upper excursions/spikes, which three appear valuable as auxiliary markers for identifying global stage boundaries. Steptoean Positive Carbon Isotope Excursion (SPICE) event with a magnitude up...
The lower Cambrian Qiongzhusi (Є1q) shale in the Sichuan Basin, formerly considered a source rock, recently achieved high gas production (7.388 × 105 m3·d−1) from well Z201 Deyang–Anyue rift trough (DART), marking an exploration breakthrough of world's oldest industrial reservoir. However, enrichment mechanism within DART is not fully understood. This study reviews formation reservoirs by comparing them with cotemporaneous deposits outside DART, and several findings are presented. interval...
The early Cambrian marks a pivotal period in metazoan evolution and ocean oxygenation through Earth's history, with sedimentary squences the Yangtze Block of South China preserving key records about biological oceanic evolution. Although significant research has focused on redox conditions shelf, slope, basin environments, their controls sulfur isotope (δ34Spy) variations, influence dynamics activity within shelf intraplatform remain unclear. This study presents observation diagnostic...
Thin-section analysis, field emission scanning electron microscopy, constant-rate mercury injection (CRMI), x-ray–computed tomography (X-CT), and nuclear magnetic resonance (NMR) were used to investigate pore systems, sizes, pore-throat distributions determine evaluation criteria for tight oil reservoirs. This research shows that the average porosity of reservoirs in Chang 63 72 Members Yanchang Formation Ordos Basin ranges from 4% 16%, with a corresponding permeability 0.1 0.4 md. The main...
The study of seepage mechanism in shale gas reservoir has been paid more and attention. reservoirs are rich nanosized pores. pores matrix can be divided into organic nanopores inorganic nanopores. At present, there many literature studies focusing on establishing a model to analyze the transport Some researchers also considered difference pores, mathematical established. However, for nanopores, most models ignore effect irreducible water distribution transport, which leads overestimating...
Studying the accumulation rules of organic matter (OM) in paleo-ocean sediments can not only enhance our understanding how OM becomes enriched ancient oceans but also provide guidance for exploration shale gas unconventional strata. A breakthrough has been made early Cambrian Qiongzhusi Formation South China. However, less attention paid to intraplatform basin Yangtze Platform, and factors controlling enrichment this special region remain unclear. This study focuses on a continuous drilling...
