Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 433-447, April 2026.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

Organoclay interaction response to sedimentary environment and sources in Paleogene shales from the Nanpu Sag: Insights for organic matter accumulation mechanism

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The deep paleo‐lake, characterised by low energy and moderate salinity, facilitated the input of fine‐grained minerals and the development of aquatic organic matter. Under the combined influence of the sedimentary environment and material source, mineral‐bound organic matter was formed, which played a crucial role in the enrichment of organic matter ...

Geochemical Analysis of Calcareous Shale of Baong Formation (North Sumatera Basin) as Potential Source Rock

open access: yesAceh International Journal of Science and Technology
This research is related to calcareous shale whose samples were obtained from surface data (outcrop). This rock outcrop is characterized as a rock rich in organic material and impermeable, so it is predicted to become a source rock of oil and gas ...

Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...
