Flexible well pattern and NPV optimisation on large scale geothermal field development

The Netherlands has set the ambitious goal to be CO2 neutral by 2050 and signed the Paris Treaty in 2015. The contribution of geothermal energy to reaching this goal are outlined in the Masterplan in 2018 which attempts to reduce CO2 emissions. It is imperative to enhance geothermal participation in renewable energy resources, so this thesis...

Reservoir quality analysis of the Triassic sandstones in the Nederweert and Naaldwijk areas: A post-mortem study

With an increase in the demand for heat energy, and the growing conscience of the world to reduce CO2 emissions, the transition to cleaner energy alternatives has gained momentum. In the Netherlands, the potential for cost-effective geothermal heat extraction from sedimentary aquifers has led to the exploration of siliciclastic Triassic...

Geothermal Aquifer Architecture Model of Alblasserdam Member in Drechtsteden, the Netherlands

The decrease in the production of hydrocarbons in combination with a growing urgency to reduce carbon emissions drives a rapid study and application of geothermal energy in the Netherlands. The produced heat from the low enthalpy geothermal energy can be used for heating up the buildings and greenhouses. A doublet system is used in the...

Reservoir Architecture Model of the Triassic Sandstones in Drechtsteden, The Netherlands

In the Netherlands, the geothermal application is implemented to produce heat from a sedimentary aquifer in the subsurface for greenhouses and district heating. The most commonly used configuration is a doublet of wells, in which one injection- and one production well is drilled to produce warm water and re-inject cool water in the same target...

Floodplain aggradation in a semi-arid endorheic basin setting, Altiplano, Bolivia

The importance of gas as a driver of security of energy supply and the influence of the role it currently has and will continue having in the energy transition has stimulated the development of further research studies in unconventional sources of natural gas. Mature gas fields of coarse-grained fluvial reservoirs have already reached their...

Geothermal Energy screening study - A comparison between Ghana and Saba

Potential volumes of arsenic in Holocene clay plug sediments in Bihar, India

Natural occurring arsenic contamination of shallow aquifer groundwater is a problem affecting millions of people worldwide. Long term exposure to high concentrations results in severe medical conditions. On-going research into the origin and spread of the problem, risk mitigation and problem solving is of great importance. Sediment eroded and...

Geological characterization of Hardegsen reservoirs

Geothermal energy is strongly dependent on the geothermal gradient; this means that with increasing depth an increase in temperature is found. The targeted formation of our research is the Hardegsen which reaches depths of around three kilometers in the West Netherlands Basin. At three kilometers depth the temperature is around 90 C˚ which is...

Correlation and modelling of a fluvial depositional system: Outcrop analogue study of thin-bedded fluvial reservoir sandstone

The Huesca fluvial fan contains a low gradient fluvial system with well-exposed, 3D outcrops. An outcrop study of low-sinuous deposits aims to provide a deterministic reservoir model that predicts correlation lengths, nesting and reservoir potential of thin-bedded fluvial reservoir sandstone in an overall low net-to-gross setting. To correlate...

Construction of a satellite-imagery-based geomorphological maps of the Uyuni salt flat, Altiplano Basin, Bolivia

The sedimentary systems terminating in the Salar de Uyuni, hold modern days analogues for the Permian and Triassic thin-bedded crevasse-splay deposits. In the future, these crevasse-splay deposits could be of importance for hydrocarbon production in Northwest Europe. In this study, the possibility of using satellite data to construct...

Sedimentologisch en Stratigrafische Analyse van Vroeg Pliocene Distale Turbidieten, NW – Corfu, Griekenland

Spontaneous Combustion of the Kimmeridge Clay Formation Oil Shale; from Geology to Modelling

Burning oil shales contribute to CO2 emissions. The spatial distribution pattern shows that these _res occur in areas with moderate or dry climates. This paper investigates the mechanism behind the burning oil shales. The first part includes an overview of the geological setting, Fieldwork results and petrophysical analyses. Based on these...
