Structural style and reservoir development in the west Netherlands oil province

The area of the Rijswijk concession largely coincides with the onshore extent of the west Netherlands basin. To date, oil has been produced from a total of 15 fields within the Rijswijk concession, which have a total STOIIP of about 210 x 10[sup 6]m[sup 3] (1.3 x 10[sup 9] bbl). Reservoirs generally comprise continental and shallow marine clastics of the Upper Jurassic of Lower Cretaceous deposited in synrift and postrift settings. The west netherlands basin was created during a phase of Late Jurassic and Early Cretaceous rifting, characterized by divergent oblique-slip faulting. This resulted in a northwest-southeast-trending block-faulted depression between the London-Brabant Massif to the south, and the Zandvoort Ridge to the north. In the subsequent postrift stage, shallow marine clastics and marls were deposited in a wide basin, with only mild synsedimentary faulting. At the end of the Cretaceous, regional uplift and convergent oblique-slip faulting resulted in basin inversion and the reverse reactivation of preexisting normal faults. Due to the transpressional nature of the basin inversion, narrow asymmetric anticlines were formed, often bounded by upward diverging reverse faults, in the hanging-wall blocks of the former normal faults. These type of structures constitute the general trap geometry of the Cretaceous oil fields in this basin. The acquisition of three-dimensional seismic data has resulted in significantly enhanced structural definition and has lead to the development of new structural and depositional models, which improve the prediction of reservoir distribution and risk assessment.
