Tambach, T.J. (author), Koenen, M. (author), Wasch, L.J. (author), van Bergen, F. (author)The short- and long-term geochemical impact of CO2 injection into a depleted gas reservoir (DGR) is investigated using reservoir/geochemical modeling with TOUGH2/TOUGHREACT and 1D kinetic diffusion modeling with PHREEQC (caprock/well-cement). Simulations of CO2 injection into the reservoir predict displacement and buoyancy of post-production CH4...article 2015

Boullenger, B. (author), Verdel, A.R. (author), Paap, B.F. (author)Seismic interferometry applied to ambient-noise measurements allows the retrieval of the seismic response between pairs of receivers. We studied ambient-noise seismic interferometry (ANSI) to retrieve time-lapse reflection responses from a reservoir during CO2 geologic sequestration, using the case of the experimental site of Ketzin, Germany. We...article 2015

Vos, P.C. (author), Bunnik, F.P.M. (author), Cohen, K.M. (author), Cremer, H. (author)This study presents the geogenetic approach to detect presently drowned archaeological sites in the transgressive palaeoenvironment of the Holocene Rhine-Meuse delta. A staged and practical approach is advocated in which subsurface archaeological predictions are based on geological mapping and palaeoenvironmental reconstruction of the underwater...article 2015

Pagnier, H.J.M. (author), Wees, J.D.A.M. (author)Indonesie heeft potenttieel veel aardwarmte, die gebruikt kan worden om elektriciteit op te wekken. Daarvan wordt nog maar een klein deel geexploiteerd. De Indonesische overheid wil in korte tijd die hoeveelheid verdriedubbelen. Het project ' GEOCAP' helpt het land hierbij. Eind 2014 ging dit project van startarticle 2015

Loeve, D. (author), Veldkamp, J.G. (author), Peters, E. (author), van Wees, J.D.A.M. (author)In the production well of a low-enthalpy geothermal doublet hot water is pumped from reservoirs at about 50-1007deg;C. After passing through a heat exchanger, the cold water is re-injected at about 20-357deg;C in the injection well into the reservoir, which initially has the same temperature as the produced water. Under some circumstances, this...conference paper 2015

Leeuwenburgh, O. (author), Hofstee, C. (author), Wilschut, F. (author)The displacement of heavy oil by water flooding is characterized by instable features known as viscous fingers. These fingers may form at very small scales, as can be observed in laboratory experiments and predicted from instability theory. Explicit representation of such features in large-scale reservoir models is practically impossible because...conference paper 2015

(author)Carbon dioxide (CO2) separated from natural gas has been stored successfully below the seabed off Norway for almost two decades. Based on these experiences several demonstration projects supported by the EU and its member states are now setting out to store CO2 captured at power plants in offshore geological formations. The ECO2 project was...report 2015

(author)In order to reach Europes 2020 and 2050 targets in terms of greenhouse gas emissions, geothermal resources will have to contribute substantially to meeting carbon-free energy needs. However, public opinion may prevent future large-scale application of deep geothermal power plants, because induced seismicity is often perceived as an unsolicited...article 2015

van der Veer, E.F. (author), Waldmann, S. (author), Fokker, P.A. (author)Underground storage of CO2 will lead to chemical fluid-rock interactions which may potentially alter the porosity and the flow patterns in faults. In this study, we present a coupled numerical model combining chemical fluid-rock interactions, aqueous diffusion, fluid flow, and mechanical processes, aiming at a better understanding of mineral...conference paper 2015

Visser, K. (author), Hendriks, D. (author), Wildenborg, T. (author), Duijne, H. (author)A semi-quantitative risk assessment is presented for the storage of gas oil in depleted salt caverns in the Twente region, the Netherlands. It is based on a bow-tie model, in which an incident, leakage of gas oil from the storage system (cavern and wells), is evaluated by assessing its possible causes and effects. The causes are all the events...article 2014

Fokker, P.A. (author), Visser, J. (author)We report a field study on solution mining of magnesium chloride from bischofite layers in the Netherlands at depths between 1500 and 1850 m. Subsidence that was observed in the area is due to part of the brine production being realized by cavern squeeze; some of which were connccted. Wc used an earlier developed inversion scheme to quantify the...conference paper 2014
