Hydrocarbon production from organic-rich shales has been proven to be feasible through numerous operations in various shale formations around the world, yet many challenges still remain, particularly with regard to potential evaluation of shale oil and gas (SOG) sources. Each year there is a growing body of new SOG reservoirs to be discovered, some of which come from the development of deep and ultra-deep organic-rich shales, typically located at 3500 m below the surface of the Earth in low-porosity-permeability formations. In general, shale can be roughly divided into three main zones on the basis of its burial depth, namely shallow shale (< 3500 m), deep shale (3500 ~ 4500 m), and ultra-deep shale (> 4500 m). Recent years the exploration of SOG from deep and ultra-deep shale formations becomes a rising star in global onshore unconventional oil and gas exploration, as deep unconventional resources production is unlocking a confusion of energy shortage and energy security. It is thus of necessity and importance to scrutinize the evaluation and characterization of SOG rocks and reservoirs.
This Research Topic aims to present and disseminate latest advances in the exploration and exploitation of both deep and ultra-deep SOG. We sincerely encourage submissions of Original Research, Review, and Perspective articles to address the following domains: (1) deep and ultra-deep SOG reservoirs, (2) coalbed methane and tight sand oil and gas, and (3) deep and ultra-deep conventional oil and gas in carbonate rocks, glutenite, volcanic rocks, and metamorphic rocks.
Topics of interest for publication include, but are not limited to:
• Potential evaluation of deep and ultra-deep hydrocarbon
• Reservoir characterization, e.g., petrophysical and organic geochemistry experiments, quantitative and qualitative characterization of multi-scale pores and fractures
• Mechanisms of pore-fracture development and preservation
• Generation, migration, accumulation, and enrichment of hydrocarbon in deep and ultra-deep reservoirs
• Mechanical properties and reservoir simulation of deep and ultra-deep reservoirs
• New techniques in exploration and exploitation of deep and ultra-deep hydrocarbon
• New techniques in “Sweet Spot” prediction of deep and ultra-deep hydrocarbon
