“…The basin is characterized by its large volumes, subsidence rates, overpressures, and diapirs which widely developed in the central Yinggehai Depression (Zhang et al, 1996;Luo et al, 2003;). These diapirs, in an en echelon arrangement, and varying in shape and size, have been recognized by their great significance in hydrocarbon exploration (Xie et al, 2001;Wang and Huang, 2008;Lei et al, 2011) (Fig. 1B).…”

“…Data from elsewhere on the Atlantic margin indicate that hot fluid events have occurred at several times since the Carboniferous Parnell et al 1999) and growing evidence from other parts of the world (e.g. Kennard et al 1999;Xie et al 2001) suggests that hot fluid pulses may be a normal feature of continental margin basins.…”

Integrated apatite fission track analysis and vitrinite reflectance data show that well 204/19-1 in the West of Shetland region, UK Atlantic margin, has experienced only limited additional burial beyond present-day depths. Uplift and cooling to present-day levels probably occurred during late Cenozoic (Eocene to Miocene) basin inversion. Fluid inclusion data indicate that Paleocene-Eocene sandstones have experienced temperatures much higher than can be explained by burial alone. Temperatures up to 200 C indicate the passage of hot fluid through Cenozoic sandstones, which by-passed the pre-Cenozoic section in this and other wells. The hot fluid event must have been of very brief duration (up to 100 years) to show no record in the fission track and reflectance data, implying that the fluids migrated through fracture systems.Oil inclusions in the Cretaceous of well 204/19-1 have a chemistry that suggests derivation from a Kimmeridgian-aged source rock. They occur in cements that show no evidence for the hot fluid event and it is concluded that the cements pre-date the event. Oil inclusions in Cenozoic sandstones have a heavy, degraded character and were trapped at high temperature, suggesting that degradation was related to the hot fluid event. Present-day oils in the West of Shetland region are mixtures, which could reflect components from the two charges distinguished by the integrated thermal and geochemical histories. The inference of fracture-bound flow is consistent with existing models of overpressure development and hydrofracturing.

“…Discontinuous seismic reflection in these structures and bright-spots along two sides of these structures (Fig. 7a, b, d) indicated the cause of fluid diapir (Xie et al 1999(Xie et al , 2001. In the diapirs, the deep strata were arched, but shallow strata were fallen which was resulted from natural gas injection in a and b (see e for the location of a-d) Mar Geophys Res (2013) 34:195-207 201 Well 3 are situated accordant with diapir in Fig.…”

“…7a, b, and revealed that the diapir is rich in CO 2 . Besides rapid subsidence, high proportion of fine sediments, high geothermal gradient, transtensional and shearing stress fields all played important roles in diapirism (Xie et al 1999(Xie et al , 2001Cartwright 1994;Wang and Xie 1998). Diapirs usually benefit from pre-existing cracks and faults formed by transtensional action such as that in Fig.…”
