ThermoGIS update: A renewed view on geothermal potential in the Netherlands

Geothermal development in aquifer settings can benefit considerably from a wealth of subsurface data acquired over the past decades by oil and gas exploration and production. In the Netherlands, this data has been gathered by the Geological Survey and has been made publicly available (www.nlog.nl). Almost a decade ago this data was used to...

Un updated and revised stratigraphic framework for the Miocene and earliest Pliocene strata of the Roer Valley Graben and adjacent blocks

In the Netherlands, the bulk of the Miocene to lowest Pliocene sedimentary succession is currently assigned to a single lithostratigraphical unit, the Breda Formation. Although the formation was introduced over 40 years ago, the definition of its lower and upper boundaries is still problematic. Well-log correlations show that the improved lecto...

The geological structure of the Netherlands continental shelf - Results of a detailed mapping project

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...

An overview of basin modeling in The Netherlands: New results and applications

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...

Reconstruction of basal heat flow, surface temperature, source rock maturity, and hydrocarbon generation in salt-dominated dutch basins

A rapidly growing demand for improved understanding of the Dutch subsurface exists because of the need for alternative energy supplies, such as geothermal energy, as well as for finding and producing more oil and gas in this mature area for petroleum exploration. We use basin modeling to integrate the wealth of new data and information that are...

Revision and update of the Callovian-Ryazanian Stratigraphic Nomenclature in the northern Dutch offshore, i.e. Central Graben Subgroup and Scruff Group

Exploration in a mature basin requires a detailed classification and standardisation of rock stratigraphy to adequately comprehend the depositional history and prospect architecture. The pre-Quaternary Stratigraphic Nomenclature of the Netherlands compiled by Van Adrichem Boogaert &Kouwe in 1993 provided a consistent framework for use by the...

New insights into the geological structure of the Netherlands; results of a detailed mapping project

A five years geological mapping project, in which the Netherlands Continental Shelf has been re-examined using all publicly available data, resulted in an important update of the existing dataset. The stratigraphy of over 400 wells has been re-interpreted. New depth and thickness grids, based mainly on the interpretation of 3D seismic data have...

Pressure and fluid dynamic characterisation of the Dutch subsurface

This paper presents and discusses the distribution of fluid and leak-off pressure data from the subsurface of onshore and offshore Netherlands in relation to causes of formation fluid overpressure and the permeability framework. The observed fluid pressure conditions demonstrate a clear regional difference between the southern and the north and...

The role of salt tectonics and overburden in the generation of overpressure in the Dutch North Sea area

In this paper we study the effects of timing of salt movement and mechanical compaction on the generation of overpressures in Mesozoic rocks. To that end we apply 2D basin modelling on two N-S trending cross sections in the Dutch Central Graben and Terschelling Basin, respectively. Several overpressuring scenarios were calculated by modifying...

Reconstruction of burial history, temperature, source rock maturity and hydrocarbon generation in the northwestern Dutch offshore

3D basin modelling is used to investigate the history of maturation and hydrocarbon generation on the main platforms in the northwestern part of the offshore area of the Netherlands. The study area covers the Cleaverbank and Elbow Spit Platforms. Recently compiled maps and data are used to build the input geological model. An updated and refined...

New findings with respect to key conditions controlling the Jurassic-Cretaceous petroleum system, Dutch Central Graben (W046)

The Netherlands represent a mature area for hydrocarbon exploration, and only less obvious targets are left for finding more oil and gas. One of these targets is the Chalk Group. This paper presents selected results of a multidisciplinary project that aims to develop a new stratigraphic trap model and migration/charge model for the Chalk in the...
