A 3D basin modeling study was carried out to reconstruct the regional heat flow and source rock maturity in the Rub'al-Khali basin. Gravity gradient data from the GOCE satellite were used to model deep structures, such as the Moho interface. Tectonic heat flow was modeled using the GOCE-based Moho interface to reflect heat flow variations in the...

In this study, we present a new experiment for following the evolution of the well integrity over time due to different changes in well conditions (pressure, temperature and fluids in contact with the well) in the context of CO2 geological storage. A small section of a wellbore is reproduced in the Opalinus Clay of the underground rock...

Natural CO2 fields provide important insights in the long-term geochemical behaviour of CO2 in a reservoir and the potential of permanent trapping in carbonate minerals. The Werkendam gas field in The Netherlands, discovered during gas exploration activities in 1991, contains >70% CO2. Core samples were selected from the Werkendam natural...

In order to be able to predict the distribution of reservoir sands and of grainsize and porosity trends in a hydrocarbon province, it is essential to understand the basin evolution in detail. In this study, an attempt is made to reconstruct the complex basin evolution of the southern Central Graben area by careful correlation of sedimentary...

technique. Although the number of applications of EnOpt has increased, and the theoretical understanding, which is based on strong assumptions, has recently significantly improved, there is still ample room for further development of the underlying theory. Here we study the mathematics (or statistics) of EnOpt and show that it is a version of an...

Main objective of the project presented in this paper is to improve the quantitative knowledge and understanding of the distribution of pore fluid pressures and fluid dynamic conditions in the subsurface of onshore and offshore Netherlands. Such knowledge and understanding is of great importance for optimizing -responsible -exploration and use...

Shale gas reservoir stimulation procedures (e.g. hydraulic fracturing) require upfront prediction and planning that should be supported by a comprehensive reservoir characterization. Therefore, understanding shale depositional processes and associated vertical and lateral sedimentological variability is key in predicting the character and...

Recent exploration activities in two of the largest deltas in the world, the still active Nile delta and the Cenozoic Southern North Sea (SNS) deltas, proved the potential of shallow gas resources. However, shallow gas production is still limited due to a lack of understanding of this gas system. For both the Nile and the SNS delta, there is an...

In 2011, TNO-GDN concluded a 5 year geological mapping of the Netherlands Continental Shelf. In this project all public data from hydrocarbon exploration were used resulting in a major update of the dataset and a variety of deliverables available at www.NLOG.NL. The stratigraphy of more than 400 wells has been re-examined and amended where...

We evaluated the implications of hydraulic stimulation in a Dutch context for low permeability clastic aquifers at a depth of 2000 to 4000 m, whose transmissivity has been mapped in the framework of the Dutch subsurface information system on geothermal energy in the Netherlands. For the simulation and well layout we adopt long horizontal well...

Life-cycle optimization is the process of finding field operation strategies that aim to optimize recovery or economic value with a long-term (years to decades) horizon. A reservoir simulation model is therefore generally appropriate and sufficient to explore the impact of different recovery scenarios. A number of challenges arise when trying to...

After the successful development of a geothermal site in 2007 in the Netherlands, interest in geothermal development has increased. The large amount of data gathered for the hydrocarbon industry shows good potential in the north of the Netherlands often in the same areas in which hydrocarbon production occurs. However, concerns about...

In order to allow quantification of the strength of local micro-seismic events recorded at the CCS pilot site in Ketzin in terms of local magnitude, earthquake data recorded by standardized seismometers were used. Earthquakes were selected that occurred in Poland and Czech Republic and that were detected both on the Ketzin array and on nearby...

A resource and performance assessment methodology has been developed to designate prospective high permeable clastic aquifers and to assess the amount of potential geothermal energy in the Netherlands. It builds from the wealth of deep subsurface data from oil and gas exploration and production which is publicly and digitally available. The...

This paper summarises the potential for surface and subsurface interactions which might occur during CO2 storage operations. We discuss possible options for managing these interactions to provide timely storage capacity, illustrated with a regional case study from the Southern North Sea. The case study evaluates storage site options to provide...

The subsurface of the onshore and offshore Netherlands has been studied extensively. In 2006 the first complete maps of the main stratigraphic horizons (down to the Permian) were published. Since then these maps were regularly updated and extended to include also the main reservoir horizons. This detailed stratigraphic information was used to...

Many CCS research projects are confined to lab or pilot scale, others restrict themselves to one or two fields of interest such as capture or storage. The first Dutch national R&D programme on CCS (CATO) and its successor CATO2 have been organized as integrated, demand-driven research programmes with a clear focus on the support of pilot...

TNO has carried out a high resolution 3D seismic survey off-shore Rotterdam. The new deployment concept that was tested with this survey results in high-quality 3D images of the shallow subsurface at relatively low cost, particularly in comparison with conventional 3D seismic data acquisition. Initially, the pilot survey aims to demonstrate the...

TNO Geological Survey of the Netherlands systematically produces 3D voxel models for answering subsurface related questions. The unique combination of vast amounts of borehole data and the voxelbased approach makes the models valuable new sources for exploring the Quaternary fluvial record. The latest generation of 3D voxel models (GeoTOP)...
