van der Meulen, M.J. (author), Koopmans, T.P.F. (author), Pietersen, H.S. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

The present contribution is an inventory of the construction raw materials policy and supply practices in The Netherlands, Belgium, North Rhine-Westphalia, Lower Saxony, Great Britain, Norway and Denmark. The work has been commissioned by the Dutch government in order to benchmark its domestic provision and the governing mineral planning policy....

Current advances in finite element computer codes and increase in computer power theoretically allow quantitative modelling of the geomechanical effects of hydrocarbon depletion from reservoirs. Here we show that it is technically possible to incorporate the full complexity of the 3D geological structure of a reservoir including faults into...

Optical dating of young coastal dunes on a decadal time scale

Ballarini, M. (author), Wallinga, J. (author), Murray, A.S. (author), van Heteren, S. (author), Oost, A.P. (author), Bos, A.J.J. (author), van Eijk, C.W.E. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

We explore the use of quartz optically stimulated luminescence (OSL) dating for reconstructing coastal evolution on a time scale of decades to a few hundred years. Samples are taken from the accretionary south-west coast of Texel, a barrier island just offshore of the northern Netherlands. The ages of dune ridges are known from historical...

The Cenozoic evolution of the Roer Valley Rift System integrated at a European scale

Michon, L. (author), van Balen, R.T. (author), Merle, O. (author), Pagnier, H. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

The Roer Valley Rift System (RVRS) is located between the West European rift and the North Sea rift system. During the Cenozoic, the RVRS was characterized by several periods of subsidence and inversion, which are linked to the evolution of the adjacent rift systems. Combination of subsidence analysis and results from the analysis of thickness...

The Dutch national research programme into the feasibility of retrievable storage of radioactive waste (CORA Programme Phase I; CORA: Comité Opslag Radioactief Afval = Committee on Radioactive Waste Disposal) examined the suitability of Tertiary clay deposts for such storage. Long-term isolation - up to 1 million years - of high-level...

Mode of lithospheric extension: Conceptual models from analogue modeling

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Michon, L. (author), Merle, O. (author)

Comparison of analogue experiments at crustal and lithospheric scale provides essential information concerning the mode of deformation during lithospheric extension. This study shows that during extension, lithospheric deformation is controlled by the development of shear zones in the ductile parts. At lithospheric scale, the global deformation...

History of petroleum systems in the southern part of the Broad Fourteens Basin

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Verweij, J.M. (author), Simmelink, H.J. (author), van Balen, R.T. (author), David, P. (author)

2D Basin modelling was used to evaluate the response of source rock maturation, and of petroleum expulsion, migration, accumulation and preservation to the evolution of the southern part of the inverted Broad Fourteens Basin. Modelling results show that the temperature, maturation and petroleum generation history as well as migration...

Expressions of shallow gas in the Netherlands North Sea

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Schroot, B.M. (author), Schüttenhelm, R.T.E. (author)

Surface and sub-surface expressions of shallow gas in the Netherlands part of the southern North Sea are described, using standard E&P 2D and 3D seismic surveys, as well as higher frequency acoustic surveys. Surface expressions observed are pockmarks, which are geomorphologic features at the seabed indicative for venting of gas, and cemented...

Geofluids in the Netherlands: Introduction

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Verweij, J.M. (author)

Traditionally, geologists focussed their research on the solid part of the subsurface. Increasingly geoscientists are aware of the role of fluids in the structural, sedimentological, mineral and (bio)geochemical evolution of the Earth’s crust. Geofluids research focusses on fluid-related processes on geological timescales. It includes a wide...

Maastrichtian or Maestrichtian? A proposal to the Subcommision on Cretaceous Stratigraphy (IUGS, International Commission on Stratigraphy)

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Herngreen, G.F.W. (author)

This contribution deals with the dual spelling of the terminal Cretaceous Stage, the Maastrichtian or Maestrichtian. From a historical point of view and in agreement with the recommendations of the International Stratigraphic Guide (1st and 2nd editions) only Maestrichtian is justified. Nevertheless, the spelling Maastrichtian is proposed, or...

Building a 3D geomechanical model of a gas field for geohazard prediction

Orlic, B. (author), van Eijs, R. (author), Zijl, W. (author), van Wees, J.D. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

Land subsidence, triggered earthquakes and wellbore instabilities are some examples of geohazards caused by or related to the production of subsurface natural resources and storage of energy residues in the deep subsurface. The main objective of geomechanical modelling is to effectively predict surface and subsurface deformation and damage due...

Modelling of deep subsurface for geohazard risk assessment.

Orlic, B. (author), van Eijs, R. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

Exploitation of subsurface natural resources, and subsurface storage of energy residues, may cause subsurface and surface deformation and damage to property. Deformation is generally difficult to assess and prove, although economical, environmental and societal interests are huge in terms of strain on granting concessions, (potential) damage...

Formation of residual NAPL in three-phase systems: Experiments and numerical simulations

Hofstee, C. (author), Oostrom, M. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

The formation of residual, discontinuous nonaqueous phase liquids (NAPLs) in the vadose zone is a process that is not well understood. The simulators have conveniently implemented the Leverett concept (Leverett and Lewis, 1941) which states that in a water-wet porous media, when fluid wettabilities follow the order water-NAPL-air, the water...

Reduction of large-scale numerical ground water flow models

Vermeulen, P.T.M. (author), Heemink, A.W. (author), Testroet, C.B.M. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

Numerical models are often used for simulating ground water flow. Written in state space form, the dimension of these models is of the order of the number of model cells and can be very high (> million). As a result, these models are computationally very demanding, especially if many different scenarios has to be simulated. Therefore we...

Paleoseismic investigations along the Peel Boundary Fault: Geological setting, site selection and trenching results

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), van den Berg, M. (author), Vanneste, K. (author), Dost, B. (author), Lokhorst, A. (author), van Eijk, M. (author), Verbeeck, K. (author)

On the basis of a multidisciplinary approach we have unraveled the palaeo-earthquake history of a trenched section across the Peel Boundary Fault. The area shows at present one of the largest contrasts in relative motion on both sides of the fault on the basis of repeated levelling. The geological record for the last 25 thousand years, recovered...

Characterisation and correlation of Tertiary seismostratigraphic units in the Roer Valley Graben

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Leeuw, C.S.de (author), Parker, N. (author), Wong, Th.E. (author)

Within the Cenozoic sedimentary section of the Roer Valley Graben ten seismostratigraphic units have been identified. They are closely related to the lithological framework which makes it possible to recognize them also on well logs in this region. The Lower Tertiary seismic units, representing mainly marine sediments, have a uniform development...
