Dynamic Prediction and Control Method for Annular Pressure in Offshore Gas Wells Based on Real‐Time Monitoring Data

Energy Science &Engineering, Volume 13, Issue 12, Page 6040-6049, December 2025.
ABSTRACT The phenomenon of annular pressure buildup (APB) is commonly observed in offshore gas wells, characterized by complex and coupled pressure types across multiple annuli. Field operations, including well shutdowns, pressure relief, and well interventions, further complicate the pressure dynamics, rendering traditional theoretical models ...

Reconstructing Early Cenozoic Paleodrainage and Tectonic Evolution in the Southeastern Tibetan Plateau: Evidence From Detrital Zircon and Tourmaline Provenance

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Paleogene sedimentary basins of southeastern Tibet record sediment dispersal patterns associated with crustal deformation during the early stages of the India–Asia collision. We present detrital zircon U–Pb geochronology, tourmaline geochemistry, and petrographic data from the Gonjo and Mangkang basins that suggest a reginal interconnected

Sediment routing from the Red River to the Yinggehai Basin during late Oligocene: detrital zircon fingerprinting of basin-mountain coupling

Frontiers in Marine Science
The Red River, which flows through several tectonic blocks in Southeast Asia, is considered to have formed in response to the Cenozoic tectonic reorganization of the SE Tibetan plateau.
