Origin of shallow gas in the Dutch North Sea - Seismic versus geochemical evidence

In the Dutch offshore, we have observed numerous acoustic anomalies, usually bright spots, in seismic data of Cenozoic deltaic deposits. When associated with shallow gas, these bright spots are good indicators of re source potential, drilling hazard, or seabed methane emissions. We apply a combined seismic and petrophysical assessment to qualify...

Spatial variation in porosity and permeability of the Rupel Clay Member in the Netherlands

The composition of groundwater in Palaeogene and older formations in the Netherlands. A synthesis

There is increasing interest in the exploitation of the deep subsurface of the Netherlands for purposes other than conventional oil and gas production, such as geothermal energy, shale gas exploitation and the disposal of radioactive waste, so for technical and environmental reasons it is important to understand the composition of the deep...

Improved subsurface property prediction in the Netherlands by integrating stratigraphic forward modelling

Classic geological reservoir characterisation relies on interpolation of high resolution well data with (at best) low resolution seismic derived data. In order to fill the data gap (e.g. in labyrinthine type fluvial deposits) we present a methodology to integrate basin scale information in reservoir scale static models by calibrating output from...

The Rupel Clay Member in the Netherlands: Towards a comprehensive understanding of its geometry and depositional environment

Thermal state of the Roer Valley Graben, part of the European Cenozoic Rift System

We performed a detailed analysis of the thermal state of the Cenozoic Roer Valley Graben, the north-western branch of the European Cenozoic Rift System, based on a new set of temperature data. We developed a numerical technique for correcting bottom hole temperatures, including an evaluation of the uncertainty of thermal parameters. Comparison...

ThermoGIS: An integrated web-based information system for geothermal exploration and governmental decision support for mature oil and gas basins

In the recent years the use of geothermal energy through implementation of low enthalpy geothermal production systems for both electricity and heating have been growing rapidly in north-western Europe. Geothermal exploration and production takes largely place in sedimentary basins at depths from 2 to 5 km. Geothermal activities can take...

Dual hydraulic behaviour of the Chalk in the Netherlands North Sea

Information on the sedimentary development, seismic stratigraphy and burial compaction of the Chalk Group in the Netherlands North Sea was combined with pressure data and basin modelling to investigate the hydraulic behaviour of the Chalk Group in the Central Graben and Schill Grund High. The preliminary results of this integrated study indicate...

Dynamic shock compaction of a ZrO2-RuO2 electronic nanocomposite: Toward functionally graded materials

Sintering, sinterforging and explosive compaction to densify the dual phase nanocomposite system Y2O3-doped ZrO2 and RuO2

Yttria-doped zirconia/ruthenia powders were made by co-precipitation. The calcined powders were compacted into green compacts using standard pressing techniques such as isostatical compaction compared to explosive compaction. Explosive compaction (EC) led to the highest density, but also to cracking of the compacts. The zirconia/ruthenia powders...

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

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...

Preparation and characterization of thin zeolite MFI membranes on porous supports

Thin (2-7 μm) polycrystalline randomly-oriented zeolite MFI membranes were prepared on an α-Al2O3 support by one or more subsequent hydrothermal treatments. Different particle sizes (275-700 nm) in the layer were achieved by changing the synthesis temperature (371-459 K). Zeolite membranes, prepared by two subsequent hydrothermal treatments have...

Two component permeation through thin zeolite MFI membranes

Two component permeation measurements have been performed by the Wicke-Kallenbach method on a thin (3 μm) zeolite MFI (Silicalite-1) membrane with molecules of different kinetic diameters, d(k). The membrane was supported by a flat porous α-Al2O3 substrate. The results obtained could be classified in six regimes based on differences in:...

Permeation of single gases in thin zeolite MFI membranes

The permeation of a series of gases with widely different Lennard-Jones kinetic diameters and sorption properties is investigated as a function of feed pressure (up to 100 kPa) and temperature (298-473 K) with two different methods. The membrane system studied consists of an MFI (silicalite) top-layer (thickness 3 μm) directly grown on an α...
