Tertiary sedimentary development of the Broad Fourteens area, the Netherlands

Abstract

The Broad Fourteens Basin is a NW-SE trending Mesozoic structural element that was affected by inversion movements during the Late Cretaceous (Subhercynian Phase) and Early Tertiary (Laramide Phase). Since the overlying Tertiary section of this area is relatively little studied, a multi-disciplinary investigation was initiated using both seismic and well data. The present study is the first phase of that project and deals exclusively with the stratigraphical framework and sedimentary development based on well logs from approximately forty wells.The Tertiary sedimentary section in this area (maximum thickness up to approximately 800 m) consists of siliciclastic rocks that generally correlate well with the established lithostratigraphical framework of the Netherlands. However, the highly variable thickness of these lithological units, illustrated by isopach maps for all units, reflect the intricate pattern of sea level movements, differential vertical movements and the ensuing erosion, that took place in this tectonically active area.Well P06-02, one of the most complete sections in the center of the area, was selected for detailed biostratigraphical analysis to support further stratigraphical subdivision and correlation. This yielded information on both the distribution pattern of various lithological units and the influence of large, partly global, events during basin development. It is concluded that application of detailed sequence stratigraphy in the study area is very problematic and only 2nd and some 3rd order cycles could be recognized.

Salt‐induced crestal faults control the formation of Quaternary tunnel valleys in the southern North Sea

“…Pelagic to hemipelagic claystones were deposited in the study area between the Palaeocene and the Middle Miocene (Wong et al . 2001). Subsequently, large deltas supplied by the palaeo‐Rhine and the Baltic River System prograded onto the North Sea (Bijlsma 1981; Clausen et al .…”

Reservoir leakage along concentric faults in the Southern North Sea: Implications for the deployment of CCS and EOR techniques

“…Major basin inversion events are recorded in the Cenozoic, the largest of which coincided with the Pyrenean Orogeny (Oligocene) and created an unconformity at the base of the Miocene (Oudmayer and De Jager, 1993;Verweij and Simmelink, 2002). It separated the Lower North Sea Group from the Middle North Sea Group (Wong et al, 2001). The boundary between the Middle and Upper North Sea Groups is based on a break of sedimentation resulting from regional uplift and global low in sea level, associated with the Alpine Orogeny (Savian unconformity, Middle Miocene) (Oudmayer and De Jager, 1993;Wong et al, 2001).…”

A comparison of burial, maturity and temperature histories of selected wells from sedimentary basins in The Netherlands

“…For the onshore area, the TNO Built Environment and Geosciences, National Geological Survey carried out a systematic subsurface mapping, compiled now in the onshore geological atlas (TNO-NITG 2004a). Several studies were published on the geology of the West Netherlands Basin, the Broad Fourteens Basin and the Groningen area (Van Wijhe 1987;Hooper et al 1995;De Jager et al 1996;DeVault 2000;Van Balen et al 2000;Wong et al 2001;DeVault and Jeremiah 2002;Verweij and Simmelink 2002;Bouw and Oude Essink 2003;Verweij et al 2003). The southern region of The Netherlands, namely the Roer Valley Graben and the adjacent highs, were examined in detail (Zijerveld et al 1992;Geluk et al 1994;Gras 1995;Gras and Geluk 1999;Van Balen et al 2002;Michon et al 2003).…”
