Geomechanical modelling of the induced seismicity for a gas field

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

Gas production from a reservoir may lead to reactivation of nearby faults, which is likely to cause local seismic events. This paper is focusing on the calculations of stress evolution during depletion of a gas reservoir in order to investigate the possibilities for the reactivation and slip on normal faults, thrust faults and bedding planes at...

Geomechanical modelling of compressive stress and overpressures in inverted basins.

Simmelink, H.J. (author), Orlic, B. (author), van Wees, J.D. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

Until now there is a lack of knowledge on quantified compressive tectonic stress and the impact on the development of overpressures. In this study geomechanical modelling of basin inversion was done to asses the feasability of the modelling tool DIANA for improved quantitative insight in the magnitude of horizontal stresses in a compressive...

Integrated geomechanical modelling at TNO for assessement of deep subsurface risks

Orlic, B. (author), Fokker, P. (author), Zijl, W. (author), Scheffers, B. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

Public authorities, E & P and the mining industry increasingly demand fundamental insight and accurate predictions on subsurface and surface deformation and damage due to exploitation of subsurface natural resources, and subsurface storage of energy residues (e.g. CO2). At this moment deformation is difficult to asses and prove, although...

Simulation of glacially-driven hydromechanical processes for safety assessment of geological disposal sites.

Orlic, B. (author), Wildenborg, A.F.B. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

The feasibility of a deep geological repository, located in clays of Tertiary age, is currently under study in the Netherlands. The clay represents a natural geological barrier, which must be able to effectively isolate the radioactive waste from the biosphere. A number of geological processes can affect the future stability of the clay, and...

Tertiary sedimentary development of the broad fourteens area, the Netherlands

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Wong, Th.E. (author), Parker, N. (author), Horst, P. (author)

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...

Modelling the evolution of hydrocarbon systems in the inverted West Netherlands Basin the Netherlands

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), van Balen, R.T. (author), van Bergen, F. (author), de Leeuw, C. (author), Pagnier, H. (author), Simmelink, E. (author), van Wees, J.D. (author), Verweij, H. (author)

The hydrocarbon systems of the West Netherlands Basin are analysed using the two-dimensional forward modelling. Three source rock intervals are considered in the modelling. The history of heatflow is calculated from the forward modelling of tectonic subsidence. Modelling results show that the oil accumulations were filled just after the Sub...

Subsidence modelling with analytic elements.

Fokker, P.A. (author), Orlic, B. (author), Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author)

The method of Analytic Elements has been extended to enable elasticity calculations, to evaluate subsidence at the surface as resulting from extraction of oil or gas. Validation has been achieved by comparison with more limited analytical methods and with a comprehensive finite-element simulator. The flexibility and the speed of the method make...

Modelling the hydrocarbon generation and migration in the West Netherlands Basin, the Netherlands

The hydrocarbon systems of the Mesozoic, inverted West Netherlands Basin have been analyzed using 2-D forward modelling. Three source rocks are considered in the modelling: Lower Jurassic oil-prone shales, Westphalian gas-prone coal deposits, and Lower Namurian oil-prone shales. The Lower Namurian hydrocarbon system of the basin is discussed for...

Late Saalian and Eemian deposits in the Amsterdam glacial basin

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Gans, W.de (author), Beets, D.J. (author), Centineo, M.C. (author)

During its maximum extension, the Saalian ice cap reached into the central Netherlands, where glacier tongues excavated over 100 m deep basins in the unconsolidated Middle and Early Pleistocene sediments. The basins are filled by relatively thick successions of Late Saalian, Eemian and Weichselian sediments. The fill of the Amsterdam glacial...

The Holocene evolution of the barrier and the back-barrier basins of Belgium and the Netherlands as a function of late Weichselian morphology, relative sea-level rise and sediment supply

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Beets, D.J. (author), van der Spek, A.J.F. (author)

Flooding of the southern part of the North Sea occurred between 9000 and 8000 BP, when the rate of relative sea-level rise was on the order of 0.7 cm per year for the Dover Strait Region and 1.6 cm per year for the area north of the Frisian Islands, forcing the shoreline to recede rapidly. When relative sea-level rise decelerated after 7000 BP...

The Eemian stage in the Netherlands: History, character and new research

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Bosch, J.H.A. (author), Cleveringa, P. (author), Meijer, T. (author)

A historical outline of the Eemian research in the Netherlands is presented as an introduction to recent research in the type area. At the end of the 19th and during the first part of the 20th century, Eemian sediments were recognized because of the presence of lusitanian and mediterranean mollusc species. From 1930 onwards, pollen analysis made...

Late Permian (Zechstein) carbonate-facies maps, the Netherlands

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

The Late Permian Zechstein carbonates in the Southern Permian Basin were deposited under marine conditions. The carbonates form part of a largely progradational infill, with a gradual northward facies shift. The paleogeography of the Zechstein carbonate deposits has been reviewed recently on the base of well data, cores and publications. This...

Provincial soil-quality monitoring networks in the Netherlands as an instrument for environmental protection

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), Busink, E.R.V. (author), Postma, S. (author)

Since 1991, several provinces in the Netherlands have put much effort in establishing soil-quality monitoring networks. The purpose of these networks is to provide insight in the trends in (geochemical) soil quality, on which new policies for environmental protection can be based, such as restrictions in certain landuse types and cleaner...

Nederlands Instituut voor Toegepaste Geowetenschappen TNO (author), van Leeuwen, R.J.W. (author), Beets, D.J. (author), Bosch, J.H.A. (author), Burger, A.W. (author), Cleveringa, P.

The Amsterdam glacial basin was a major sedimentary sink from late Saalian until late Eemian (Picea zone, E6) times. The basin's exemplary record makes it a potential reference area for the last interglacial stage. The cored Amsterdam-Terminal borehole was drilled in 1997 to provide a record throughout the Eemian interglacial. Integrated facies...

The Eemian stratotype locality at Amersfoort in the central Netherlands: A re-evaluation of old and new data

In order to obtain a better understanding of the infilling of the Saalian glacial basins during the Eemian, particularly following the recent research in the Amsterdam Basin (Terminal borehole), it was necessary to re-investigate the type locality of the Eemian at Amersfoort. Both published and unpublished data from various biota (diatoms,...

We started a geochemical mapping campaign in the Early Pleistocene fluviatile Kedichem Formation in the Netherlands in order to meet the demand for more information about subsurface sediment compositions. Geochemical data were collected during a sampling campaign, and about 600 samples from the Kedichem Formation were analyzed. By linking the...
