A synthetic study of acoustic full waveform inversion to improve seismic modelling of firn
Annals of Glaciology, 2022 The density structure of firn has implications for hydrological and climate modelling and for ice shelf stability. The firn structure can be evaluated from depth models of seismic velocity, widely obtained with Herglotz-Wiechert inversion (HWI), an ...

Structural Interpretation of the Qingdong Area in Bohai Bay Basin from Shipborne Gravity Data
Polish Maritime Research, 2015 The Qingdong area, located in Bohai bay basin, was suspected good exploration prospects. In order to study tectonic features and find out favourable petroleum prospects in the area, the gravity data at a scale of 1:50,000 were interpreted.

Depth migration of crustal-scale seismic reflection profiles: A case study in the Bohai Bay basin
Frontiers in Earth Science, 2023 The application of the pre-stack depth migration (PSDM) method using deep seismic reflection data is still a challenge. In this paper, a deep seismic reflection dataset collected from the Bohai Bay Basin is used to test the applicability of the pre-stack

Identification and Interpretation of fan deposits in Block H12 of Beixi subsag, Beier depression, Hailar basin [PDF]
E3S Web of Conferences, 2020 Fan deposits in the Nantun formation in Beier depression have been drilled in the past two decades. It’s difficult to identify and describe subtle traps formed by fans by seismic interpretation. By using a combination of seismic interpretation techniques
