Introduction
As a carbonate sedimentologist, my research has focused on physico-chemical and microbiological processes that shape the sedimentary fabric from its deposition through its diagenesis. Developing a quantitative approach has been an important target, using field and lab experiments, 3D high-resolution observations and geochemistry. This also facilitates addressing more applied questions in relation to diverse geo-energy resources including pore network evolution and modelling.

Article
Full-text available
Spring systems are efficient and fast precipitating non‐marine carbonate factories, but they are also prone to (early) diagenesis. Evidence of diagenesis in travertines remains controversial as the resulting textures have been considered primary in other deposits and the impact on geochemical/palaeo‐environmental signals is often poorly addressed....

Full-text available
Applying an integrated methodology, including petrography, Mercury Injection Capillary Pressure, laboratory Nuclear Magnetic Resonance and X‐ray Computed Tomography, on continental spring carbonate reservoir analogue samples is a prerequisite to understand plug scale porosity and permeability heterogeneities. Depending on the dominant pore type in...
Article
Due to their large heat and moisture storage capabilities, the tropics are fundamental in modulating both regional and global climate. Furthermore, their thermal response during past extreme warming periods, such as super interglacials, is not fully resolved. In this regard, we present high-resolution (analytical) foraminiferal geochemical (O and M...

Accurate prediction of permeability evolution is essential for forecasting the long-term performance and lifetime of hydrothermal reservoirs, an important goal in the geothermal, ore, and petroleum industries. Erol et al. (Transp Porous Media 120(2):327-358, 2017. https ://doi.org/10.1007/s1124 2-017-0923-z) introduced a general (non-empirical) ana...
Article
Non-marine carbonate rocks including cave, spring, stream, calcrete and lacustrine-palustrine sediments, are susceptible to early diagenetic processes. These can profoundly alter the carbonate fabric and affect paleoclimatic proxies. This review integrates recent insights into diagenesis of non-marine carbonates and in particular the variety of ear...
Article
This study compares and contrasts the travertine depositional facies of two of the largest sites of travertine formation, located in very different geological contexts, i.e. the modern Mammoth Hot Spring (MHS) system in the active volcanic complex of Yellowstone National Park (USA) and the Pleistocene Cakmak quarry, a well-exposed example of the Ba...
Article
Full-text available
Carbonate spring deposits gained renewed interest as potential contributors to subsurface reservoirs and as continental archives of environmental changes. In contrast to their fabrics, petrophysical characteristics – and especially the importance of microporosity (< 1µm) – are less understood. This study presents the combination of advanced petroph...
Article
Nowadays most low-field NMR sensors, such as the single-sided Profile NMR-MOUSE®, still suffer from poor sensitivity, either resulting from low magnetic field strengths and correspondingly low NMR frequencies, or lack of sensitivity. Generally, micro-coils can improve sensitivity, but due to their small size, and thus small inductance, they are mai...
Article
Full-text available
In the last 10 years numerous research and commercial initiatives have been undertaken in Europe to develop abandoned coal mining fields into low-temperature resources. One of the most successful is the Minewater project of the municipality of Heerlen, the Netherlands, where a low-temperature district heating system was launched in operation in Oct...
Article
Full-text available
Faults can determine the success or failure of low enthalpy geothermal projects. This is due to their capacity to behave as pathways or baffles to geothermal water (or both simultaneously) and their prevalence throughout the subsurface. Here we present an initial assessment of the possibility for faults in the Northern Belgium (Flanders) and Nether...
Conference Paper

Faults often determine the success or failure of low enthalpy geothermal projects. This is due to their prevalence throughout the subsurface and capacity to behave as significant fluid flow pathways or baffles (or both simultaneously). Here we present the methodology and results of an assessment of the capacity of faults in the Belgium and Netherla...
Article
Full-text available
An increasing need exists to quantify the impact of diagenesis on complex and heterogeneous geological reservoirs and to predict the related field-scale porosity-permeability distribution. Development of approaches to quantify diagenetic events is an important step towards the construction of integrated numerical reservoir models predicting the imp...

Quantification and Prediction of the 3D Pore Network Evolution in Carbonate Reservoir Rocks - This study presents an integrated approach that allows the reconstruction and prediction of 3D pore structure modifications and porosity/permeability development throughout carbonate diagenesis. Reactive Pore Network Models (PNM-R) can predict changes in t...
Article
Faults are often important in fuelling methane seep systems; however, little is known on how different components in fault zones control subsurface fluid circulation paths and how they evolve through time. This study provides insight into fault-related fluid flow systems that operated in the shallow subsurface of an ancient methane seep system. The...
Article
Terra Nova, 23, 56–61, 2011 Authigenic carbonates at methane seeps provide valuable information on the evolution of seepage dynamics. In this study, we report on an unusual type of 13C-depleted [δ13C: −44.8‰ to −8.3‰V-PDB (Vienna PeeDee Belemnite)] calcite-cemented grapestone concretion composed of small spheroidal nodules, <0.1–15 cm across, assoc...
Article
Impressive, several meters high tubular concretions in shallow marine calcareous sands and sandstones represent part of the well-exposed, subsurface plumbing network of an Early Eocene methane seep system in the Balkanides foreland (Pobiti Kamani area, Varna, NE Bulgaria). An integrated approach, including petrography, inorganic geochemistry and li...
Article
Up to 10m in length and >1m in diameter tubular, calcite-cemented sandstone concretions are hosted by the faulted Dikilitash unconsolidated sands and sandstones. These structures document shallow subsurface pathways of Early Eocene methane seepage in the Balkan Mountains foreland (NE Bulgaria). Their exceptional exposure allowed a unique study of t...

In the Pobiti Kamani area, up to 10 m high and meter-diameter tubular concretions (so-called columns) are exposed within Lower Eocene sands and sandstones (Dikili Tash Formation) about 20 km west of Varna (NE Bulgaria). These calcite-cemented sandstone concretions have been a subject of many geological studies addressing their formation. In the pre...
Article
The genesis of Lower Eocene calcite-cemented columns, “pisoid”-covered structures and horizontal interbeds, clustered in dispersed outcrops in the Pobiti Kamani area (Varna, Bulgaria) is related to fossil processes of hydrocarbon migration. Field observations, petrography and stable isotope geochemistry of the cemented structures and associated ear...
Article
In the area of Pobiti Kamani (Varna, northeast Bulgaria), massive carbonate cemented columns (“chimneys”, up to 1.5 m diameter and 8 m high) and horizontal interbeds (≤1.5 m thickness) occur in dispersed outcrops over an area of 70 km2 within loose Lower Eocene sands. Field observations and petrographical and stable isotope geochemical characterisa...

The Mercator mud volcano, located in the Gulf of Cadiz off the coasts of Spain, Portugal, and Morocco (Figure 1), may provide an accessible field laboratory for studying local active venting and its possible internal and external controls. The recent discovery of the first active deep ocean `brown smoker' chimney in this area can possibly be linked...
Article
Detailed geophysical, geochemical and petrological data over a cluster of large mud volcanoes at the Moroccan North Atlantic margin document the activity of sea floor mud volcanoes in relation to its morphology and structural setting. Mud volcanoes are often long-lived systems; their changing morphology bears witness of the evolution of fluid flow...
