Reyes Lastiri, D. (author)
Heating constitutes about 40% of the final energy consumption at TU Delft. In the present, the district heating system in campus obtains its energy from the combustion of natural gas in a combined heat and power plant. Although this plant produces heat and electricity with an efficiency over 80%, the dependance on a fossil fuel presents an...

Bisdom, K. (author)
The main challenge of naturally fractured reservoirs (NFRs) is understanding how fractures behave in the subsurface outside the radius of influence of wells. Fractured outcrop analogues provide geological concepts that can be used to extrapolate fracture data outside the well control. Numerous methods for studying fractured outcrops are...

Holt, S. (author)
The upstream oil and gas industry focuses increasingly on unconventional gas resources to maintain the level of its hydrocarbon reserves. To unlock the full potential of gas shale reservoirs, horizontal wells are drilled and active stimulation of the reservoirs, in the form of multi-stage hydraulic fracturing, is performed. This new technique...

Since industrial revolution, due to the increasing demand of energy, anthropogenic emissions in the atmosphere are constantly growing. The International Energy Agency (IEA) predicted a 57% increase of energy demand from 2004 to 2030 (IEA, 2004) of which, 85% consists of fossil fuels. Actions need to be taken in order to mitigate CO2 emissions...

From a system-theoretical point of view and for a given configuration of wells, there are only a limited number of degrees of freedom in the input–output dynamics of a reservoir system. This means that a large number of combinations of the state variables (pressure and saturation values) are not actually controllable and observable from the...

El Allouche, N. (author)
The shallow marine subsurface is explored for various engineering purposes e.g. constructing installations and platforms, laying pipelines and dredging for sand. Knowledge of the soil properties is essential to minimize the risks involved with these offshore activities. Energy resources in the form of gas hydrates and hydrocarbon reservoirs are...

Kavian, M. (author)
As geophysicists we are interested in the capabilities of electromagnetic methods for exploration, characterization, and monitoring of the subsurface. For frequencies below 1 MHz, the electromagnetic field is primarily diffusive, rendering the method very little resolving power. For this reason the resistivity values of layered structures cannot...

Paulissen, W.E. (author)
Sedimentary basins form in a range of large-scale tectonic settings involving extensional, compressional or lateral movements. The dynamics of the basin infill are controlled by driving mechanisms such as tectonics, climate and eustatic control. The created accommodation space in the basin is filled by sediments that formed by erosion in the...

Schakel, M.D. (author)
Coupled seismic and electromagnetic wave propagation is studied theoretically and experimentally. This coupling arises because of the electrochemical double layer, which exists along the solid-grain/fluid-electrolyte boundaries of porous media. Within the double layer, charge is redistributed, creating an excess electrical charge in the fluid...

The interface-wave impedance and ellipticity are wave attributes that interrelate the full waveforms as observed in different components. For each of the fluid/elastic-solid interface waves, i.e., the pseudo-Rayleigh (pR) and Stoneley (St) waves, the impedance and ellipticity are found to have different functional dependencies on Young’s modulus...

Hoekstra, B.E. (author)
In-Situ Combustion (ISC) is a thermal enhanced oil recovery method. Therefore, air or oxygen-enriched air is injected in the reservoir. The oxygen reacts with part of the hydrocarbon forming heat and combustion products. The released heat increases the temperature locally in the reservoir and lowers the viscosity of the oil. Formed gaseous...

This paper analyzes traveling wave profiles possessing an internal resonance point for a class of systems of partial differential equations describing oxidation and vaporization of liquid fuel in a porous medium when an oxidizer (air) is injected. It is shown that the resonance is characterized by a saddle point of an associated vector field...

Clean drinking water is essential for life. In Bangladesh and the northern part of India however, around the 30 and 40 million people are estimated to be exposed to Arsenic in drinking water at concentrations above the 0.05 mg/L. Studies show that the aquifers of Holocene age near the Ganga River are polluted. These aquifers are between the 10...

Beachrocks are lithified coastal sedimentary formations which form inside the beach body on short time scales, possibly within a year. Beachrocks can play an important role in the evolution of a shoreline as they fix the normally loose sediments. On the other hand, the evolution of a shoreline could play an important role in the genesis of...

More than the half of the Netherlands is under the high level of sea and rivers. Therefore, evaluating the safety of dykes is primordial. A specific interest is given to peat dykes safety which suffer of a lack of knowledge which manifested recently by some peat dykes failures (Van Baars 2005). The behaviour of peat is also of interest in others...

Menzel-Jones, G. (author)
Elastodynamic and electromagnetic processes are coupled together in saturated, porous media, by a phenomenon known as the electrokinetic effect. In horizontally layered media, the seismoelectric system, which contains the coupled elastodynamic and electromagnetic systems, can be separated into two independent modes of propagation: SH-TE and P-SV...

We measured the electric parameters for four different configurations of unconsolidated homogeneous and layered sands as a function of frequency, water saturation, and salinity under fluid flow conditions. Our objective is to determine if the effect of heterogeneities at scales much smaller than the skin depth can be captured by introducing...
