82nd EAGE Annual Conference & Exhibition, 2020
Summary Detailed experimental studies on the seismic properties of shale samples from different reservoirs have been conducted both in the laboratory and in situ under different conditions. In a previous study, Johnston and Wang (1981) measured the ultrasonic velocity anisotropy of Cretaceous shale in the Willison basin under undrained conditions ...

Abstract A large, typical, marine, organic-rich shale is developed in the Ordovician Wufeng Formation-Silurian Longmaxi Formation in the Sichuan Basin, China, which has rich shale gas resources. This paper uses this type of shale as an example to analyze the influence of the depositional environment on the enrichment mechanisms and sedimentary ...

Pyrite from outcrops of Late Ordovician–Early Silurian marine shales of the Sichuan Basin was studied in the laboratory setting. We characterized various occurrences of pyrite using optical microscopy, reflected light microscopy, X-ray analysis, scanning electron microscopy, and energy-dispersive analysis, and image analysis to aid visual estimates of ...

The fracturing technology for shale gas reservoir is the key to the development of shale gas industrialization. It makes much sense to study the mechanical properties and deformation characteristics of shale, due to its close relationship with the fracability of shale gas reservoir.

Abstract In shale gas reservoirs, scientific consensus indicates that the main pore types are organic matter pores, mineral pores and micro-fractures. The organic matter pores are crucial to porosity, and in many cases they form the main pore type favorable for shale gas enrichment.

ABSTRACTThe physical properties of shale reservoirs are critical to the enrichment mechanisms of shale oil and gas. To clarify the differences in reservoir physical properties and their primary controlling factors of the Wufeng‐Longmaxi Formation shales in northern Guizhou, this study systematically employed multi‐scale characterisation techniques ...
