Coupled kinematic and thermal modelling of collisional orogens: Implications for subsurface geo-resources assessment in the external Dinarides

The thermal evolution of collisional orogens is largely controlled by their kinematic and burial/exhumation history, where sedimentation and erosion rates, as well as shear heating and deep heat flow supply conditions for the temperature distribution, fluid flow and the associated fluid-rock interactions. The aim of our research is to understand...

The development of a future chemical compatibility standard for energetic materials

To ensure safety and reliability, it is important that the explosives and other materials used in munitions do not interact adversely either physically or chemically. Data obtained by heat flow calorimetry on nitrocellulose-based propellants have been reviewed with the aim of identifying improved chemical compatibility assessment criteria. It...

Geothermal energy in deep aquifers: A global assessment of the resource base for direct heat utilization

In this paper we present results of a global resource assessment for geothermal energy within deep aquifers for direct heat utilization. Greenhouse heating, spatial heating, and spatial cooling are considered in this assessment. We derive subsurface temperatures from geophysical data and apply a volumetric heat-in-place method to improve current...

On the Importance of Thermo-elastic Stressing in Injection-Induced Earthquakes

The sustainability of geothermal fields is based on a paradox. On one side, fractures are targeted on heat-flow improvement, and on the other side, the same fractures are avoided because of induced seismicity risk. In this context, we developed analytical approaches for estimating (1) thermo–poro-elastic stresses in a fractured geothermal system...

GOCE gravity gradient data for lithospheric modeling

The Gravity field and steady-state Ocean Circulation Explorer (GOCE) is the European Space Agency's (ESA)satellite gravity mission to determine the Earth's mean gravity field. GOCE delivers gravity gradients, anew type of satellite data. We study how these data can improve modeling of the Earth's lithosphere. We discuss the use of the original...

Assessment of stability of propellants and safe lifetimes

The surveillance of gun propellants is basically performed either by an investigation into the thermal behavior of the propellant or by the determination of its remaining effective stabilizer content. Over the years it is shown that the surveillance of NC based gun propellants is necessary. NC based materials are intrinsically unstable, and can...

Reconstruction of tectonic heat flow in the Rub'al-Khali basin relying on an updated crustal model

3D subsurface temperature model of Europe for geothermal exploration

For the assessment of geothermal resources in Europe we constructed a digital 3D temperature model of the European crust and sedimentary basins, incorporating publicly available temperature data. Using European crustal thickness models and indirect parameters such as surface heat flow measurements, temperatures were calculated for regions where...

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...

Round-robin test of heat flux sensors

The first intercomparison on the density of heat flow-rate measurements has been organized by MKEH (Hungarian Trade Licensing Office, Metrology Division) within the framework of EUROMET (Project No. 426). This round-robin test gives evidence about the measurement capabilities of the local realizations of a density of a heat flow-rate scale up to...

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...

A batch process micromachined thermoelectric energy harvester: Fabrication and characterization

Micromachined thermopiles are considered as a cost-effective solution for energy harvesters working at a small temperature difference and weak heat flows typical for, e.g., the human body. They can be used for powering autonomous wireless sensor nodes in a body area network. In this paper, a micromachined thermoelectric energy harvester with 6...

Probabilistic tectonic heat flow modeling for basin maturation: Assessment method and applications

Tectonic modeling is often neglected in the basin modeling workflow and heat flow is most times considered a user input. Such heat flows can, therefore, result in erroneous basin modeling outcomes, resulting in false overoptimistic identification of prospective areas or failure to identify prospects. This is particularly true for areas with...

Tectonic heat flow modelling for basin maturation - Implications for frontier areas in the mediterranean

Basement heat flow is one of the most influential parameters on basin maturity. Although rapid progress has been made in the development of tectonic models capable of modelling the thermal consequences of basin formation, these models are hardly used in basin modelling. To better predict heat flows we have developed a multi-1D probabilistic...

Pre-screening tectonic heat flows for basin modelling - Some implications for deep water exploration in the mediterranean

Basin modelling results can be very sensitive to (paleo-)temperature uncertainties. For frontier basins, in particular for deep water settings, the thermal signature of the basin is poorly constrained, as data from wells are lacking. This may lead to wrong heat flow assumptions if these are extrapolated from the shallow offshore or onshore....

Sample geometry as critical factor for stability research

Stability research on gun propellants has been widely performed by microcalorimetry since the 1980s. TNO Prins Maurits Laboratory has already a broad experience since the early 1970s. In the past many studies were performed, to investigate the influence of oxygen, humidity etc. Less attention was paid to two other important aspects, namely the...
