Moghadam, A. (author), Castelein, C.J.K. (author), ter Heege, J.H. (author), Orlic, B. (author)Presence of microannuli at the cement interfaces in wellbores could provide a path for fluid leakage. In this study, we combined experimental analysis and numerical modelling to assess microannuli development at casing–cement interfaces. Lab experiments were conducted using two-metre long samples consisting of a 7’’ casing cemented inside a rock...article 2022

Candela, T. (author), Goncalves Machado, C. (author), Leeuwenburgh, O. (author), ter Heege, J.H. (author)A newly developed modelling framework is presented which specifically focusses on the central Oklahoma case and the high-volume injection of wastewater, which led to a surge of induced seismicity. However, the modelling framework is versatile enough to be applied to any anthropogenic subsurface activities and should be seen as a good practice to...article 2022

Moghadam, A. (author), Castelein, C.J.K. (author), ter Heege, J.H. (author), van der Valk, K. (author), Orlic, B. (author), Wollenweber, J. (author)Maintaining the integrity of the annular cement in the wellbore is paramount in successful hydrocarbon exploitation, subsurface energy storage, geothermal energy production, and geologic carbon sequestration. Debonding at the casing-cement interface can create connected flow paths for fluid leakage along the well leading to loss of zonal...conference paper 2020

ter Heege, J.H. (author), Wassing, B.B.T.0 (author), Candela, T. (author)Subcritical crack growth can contribute to stimulation of permeability in geothermal reservoirs as it can lead to lower formation breakdown pressure and enlargement of fracture disturbed zone. This study examines tensile and shear failure due to fluid injection and axial compression in tight sandstones. The overall aim is to identify effects of...conference paper 2020

(author)Geothermal energy aids in achieving ambitions for the reduction of greenhouse gas emissions by contributing to a more sustainable energy mix. In particular, geothermal energy in the Netherlands can play an important role in providing a sustainable supply for domestic and industrial heat demand.

ter Heege, J.H. (author)The spatial distribution of reactivated fractures and fracture permeability after stimulation are key controlling factors that determine typical drainage areas, shale to well connectivity, and hydrocarbon flow rates in fractured shales. In this paper, the influence of fault and fracture populations on the permeability of fractured shales is...conference paper 2016

ter Heege, J.H. (author), Pizzocolo, F. (author), Osinga, S. (author), van der Veer, E.F. (author)Faults and fractures in hydrocarbon reservoirs are key to some major production issues including (1) varying productivity of different well sections due to intersection of preferential flow paths with the wellbore, (2) varying hydrocarbon column heights in different reservoir compartments due to differences in the sealing capacity of faults, and...conference paper 2016

Osinga, S. (author), Pizzocolo, F. (author), van der Veer, E.F. (author), ter Heege, J.H. (author)Fractured rocks play an important role in many types of petroleum and geo-energy operations. From fractured limestone reservoirs to unconventionals, understanding the geomechanical behaviour and the dynamically coupled (dual) permeability system is paramount for optimal development of these systems. Traditionally, incorporating fracture systems...conference paper 2016

ter Heege, J.H. (author)The occurrence and properties of natural faults and fractures in geothermal reservoirs are key in determining reservoir flow properties, and thereby the performance of geothermal doublets placed in fractured reservoirs or in the vicinity of fault zones.

Pizzocolo, F. (author), Hewson, C.W. (author), ter Heege, J.H. (author)Subsurface CO2 storage has been identified as one of the key methods to reduce the emission of CO2 to the atmosphere. Remediation or mitigation of unwanted migration from potential storage sites requires novel approaches for which feasibility is yet to be demonstrated. This study focuses on a solution to mitigate CO2 migration through naturally...conference paper 2016
