Time-Resolved model for geothermal engineering in high porosity Slochteren sandstone

This work is an extension of the time-resolved poro-elasto-plastic MohrCoulomb model by Fokker et al to include a more realistic constitutive model. Experiments on Slochteren sandstone revealed that the inelastic deformation contributes significantly in compressive deformation almost in all stages of loading and instigated the development of a...

Article in press: Stable isotope stratigraphy of the early Quaternary of borehole Noordwijk North Sea

Between 2.58 Ma and 2.4 Ma, most of the present onshore sector of the Netherlands was an epicontinental sea. Previous studies suggest the occurrence of multiple cold and warm phases in shallow marine successions of the Maassluis Formation in conjunction with the first prominent Northern Hemisphere ice sheet expansions. Nevertheless, correlation...

Pressure information system of the onshore and offshore Netherlands

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...

Intentional salt clogging: A novel concept for long-term CO2 sealing

Well abandonment in the context of CO2 storage operations demands a mitigation strategy for CO2 leakage along the wellbore. To prevent possible CO2 transport toward the surface and to protect the wellbore material from contact with acid brine, we propose forming a salt seal around the wellbore at reservoir level, after CO2 injection into a...

Geochemical reactivity of subsurface sediments as potential buffer to anthropogenic inputs: A strategy for regional characterization in the Netherlands

Purpose: Sedimentary aquifers are prone to anthropogenic disturbance. Measures aimed at mitigation or adaptation require sound information on the reactivity of soil/sediments towards the infiltrating water, as this determines the chemical quality of the groundwater and receiving surface waters. Here, we address the issues of relevant sediment...

Sedimentary facies, correlation, and architecture of Rotliegend reservoirs at the Southern Permian basin margin: The P01-FA case study and the challenged myth of layer-cake stratigraphy

Sedimentology, log analysis, and high-resolution seismic data of the P01-FA structure, located in the western part of the Netherlands sector of the North Sea, were used to assess the correlatability and connectivity of the sand bodies, to unravel the complex internal reservoir architecture, and to demonstrate the impact that different conceptual...

Feasibility of borehole radar measurements to monitor water/steam fronts in EOR applications

A technique capable of capturing the dynamic of the reservoir fluids in the proximity of production wells would provide enormous benefit to the reservoir management; in fact, monitoring can be used to develop a feedback loop between measurements and control technologies to optimize the production. This paper examines the feasibility of a...

Chronostratigraphy of Late Neogene sediments in the southern North Sea Basin and paleoenvironmental interpretations

A chronostratigraphic framework has been established for Upper Neogene sediments from the northern Netherlands offshore sector, southern North Sea. Data of dinoflagellate cysts, pollen and foraminifers from eight boreholes are integrated and the resulting biostratigraphic events are connected to an additionally retrieved paleomagnetic record....

Interval velocities of a triassic claystone: Key to burial history and velocity modelling

Interval velocities of the Lower Triassic Main Claystone Member have been evaluated and mapped for some 460 boreholes in the Dutch on- and offshore. A simple model was adopted for the dependence on depth of compressional wave velocities of sediments. Based on this model, interval velocities were interpreted in terms of burial and apparent uplift...

Onshore and offshore seismic and lithostratigraphic analysis of a deeply incised Quaternary buried valley system in the Northern Netherlands

High-resolution seismic data (onshore and offshore), geophysical borehole data as well as detailed lithofacies from airlift boreholes were acquired in northern Netherlands on and around the island of Ameland. Marine and land seismic data combined with information from land boreholes have been explored with the objective of providing a...

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

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...
