PGK at EAGE conference

Wednesday 9 July 2014

The PGK was represented at the recent EAGE conference in Amsterdam (16-19 June 2014) with a booth at the Exhibition.  EAGE dignitaries including outgoing and incoming presidents Gladys Gonzalez and Phil Ringrose visited the PGK booth in presence of Chairman Aafke Bouma and Vice Chairman Paul Huibregtse during the Associated Societies Tour (picture on the right).

Structural development of the Dutch Central Graben: new ideas from recent 3D seismic.
Rosendaal, E.A. (presenter), Kaymakci N., Wijker, D., Schroot, B.M.

A regional study on the northern Dutch Central Graben (DCG) and Step Graben (SG) based on, amongst others, very recent regional 3D seismic data has resulted in new ideas on the structural development of the area.

It is postulated that main rifting of the DCG occurred during Middle to Late Triassic. The Late Jurassic extensional phases and the Early Cretaceous inversion phases affected the NS orientated DCG and SG in a different way than the NW-SE orientated basins. There is no evidence in the study area that during the NE-SW Late Jurassic extension, the NS bounding faults were reactivated. WNW-ESE extensional faults developed or were reactivated creating a graben stepping down to the north. Furthermore, it seems that the Early Cretaceous inversion also did not reactivate the NS bounding faults but manifests itself only in a broad basin uplift with minor transpressional features.

We expect to improve our understanding of the timing of events, erosion amounts and paleogeography. We foresee future basin modeling to obtain further insights into the hydrocarbon maturation history. The observed WNW-ESE fault trends in the DCG could have tectonically controlled Late Jurassic to Early Cretaceous sedimentation and local accommodation space along the fault escarpments may create interesting opportunities for hydrocarbon exploration.

Late Jurassic rifting in the southern Central Graben: a complex story simplified

A detailed understanding of the basin evolution is essential in hydrocarbon exploration: the distribution of reservoir sands and trends in grain size and porosity are directly related to it. In this presentation an attempt is made to reconstruct the complex basin evolution of the southern Central Graben area by careful correlation of sedimentary successions from the various sub-basins and intermediate plateau areas.

The Late Jurassic rift phase is complex: an important change in extension direction and in structural style occurs, subsidence varies dramatically through time and space and depocenters shift from one place to the other. Three major steps are recognized in the Late Jurassic basin evolution, each of which is closely related to changes in the tectonic regime. In the Southern Central Graben late Jurassic rifting starts with the Graben Axis phase, where subsidence is related to E-W extension and remains limited to the graben axis. At the end of this phase, the tectonic regime changes into NE-SW extension, which is accompanied by the formation and reactivation of NW-SE normal faults. The areas alongside the graben axis become active basins during this time. As a consequence, this phase is referred to as the Peripheral Basins phase. The final phase in the Late Jurassic basin evolution is characterized by waning fault activity and shedding of marine sediments onto the adjacent plateaus; hence the Adjacent Plateau phase. After the last rifting phase, a large-scale marine transgression blankets the entire Central Graben area. From then on, regional subsidence related to thermal cooling becomes prevalent for a long period of time.
