(author)Surface movement can be induced by many human subsurface activities: production of natural gas, geothermal heat extraction, ground water extraction, phreatic groundwater level lowering, storage of natural gas and CO2. In this manuscript, we focus on subsidence caused by gas production. While geological interpretations, seismic campaigns and flow...article 2022

(author)Coals are heterogeneous and the zones of interest for gas production (high fracture density) are often friable. 3D printed (3DP) rocks can create a repeatable analogue by minimizing specimen variability. This study investigates a series of 3DP coal seam gas packages under various flow conditions to determine the impact of fracture network and...article 2022

(author)Rock salt formations are a common reservoir seal worldwide with excellent sealing capacity. Restoring the sealing capacity of rock salt caprocks penetrated by wells using the same rock salt as plugging material is therefore an attractive, safe and environmentally friendly option. The concept is based on the removal of a section of casing over a...conference paper 2019

(author)Wells used for steam-assisted gravity drainage (SAGD), for cyclic steam stimulation (CSS), for hydrocarbon production in areas with anomalous high geothermal gradient, or for geothermal energy extraction all are operated in high temperature environments where maintaining long term wellbore integrity is one of the key challenges.

(author)Loading history during drilling, completion and operations of the well can affect wellbore integrity. Debonding along well cement interfaces leads to the creation of micro-annuli and potential leakage pathways. We investigate the risk of debonding by modeling the integrity of an example well throughout its life-time using a finite element...conference paper 2018

Fokker, P.A. (author), Osinga, S. (author)Fast models to estimate subsidence resulting from subsurface extraction processes usually employ a nucleus-of-strain solution based on a center of compression. The solution for such a strain nucleus is then employed as an influence function. This approach is based on the superposition principle that applies for linear elasticity of the...conference paper 2018

The complexity of faults obtained from geological and seismic characterization is usually not honored in flow models for fractured reservoirs. Fault zone architectures may...conference paper 2018

(author)The petroleum systems of two adjacent Miocene intraslope minibasins in the northern deep-water Gulf of Mexico are modeled to investigate why one of them produces primarily gas but the other produces oil. Specifically, the Mensa field produces gas from a faulted four-way closure that overlies a turtle structure, whereas the adjacent Thunder Horse...article 2017

TerHeege, J.H. (author), Orlic, B. (author), Wollenweber, J. (author)Geothermal drilling environments are often hostile to well materials, especially in magmatic settings where properties of well casing and cements may rapidly change as a result of high temperatures and chemically active formation fluids. Prolonging the lifetime of such geothermal wells is one of the key challenges to achieve a commercially...conference paper 2017

(author)Large-scale CO2 injection in saline aquifers will cause pressure build-up in brine far beyond the extent of CO2 plume. In this paper, we evaluate the geomechanical responses of large-scale CO2 storage in the multilayer aquifer of the Kra Al-Maru Trend in Kuwait. The site was selected after screening the whole territory of Kuwait, identifying and...conference paper 2017

(author)Pressure maintenance by injection of nitrogen into a reservoir is one of the potential options to mitigate induced seismicity during gas production. It is expected that seismicity and the seismic hazard can be reduced by decreasing the stress changes and compaction associated with the declining pore pressure in the reservoir rocks. However,...conference paper 2017

Antropov, A. (author), Lavrov, A. (author), Orlic, B. (author)Cap-rock integrity is of paramount importance during injection and subsequent long-term storage of CO2 in the subsurface. Preexisting (natural) and man-induced fractures in the cap rock represent potential flow paths out of the storage formation. In this study, a first-order semi-analytical model of flow through a vertical fracture penetrating...conference paper 2017

Smit, J. (author), van Wees, J.D. (author), Cloetingh, S. (author)The crustal seismic velocity structure of northwestern Europe shows a low P-wave velocity zone (LVZ) in the lower crust along the Caledonian Thor suture zone (TSZ) that cannot be easily attributed to Avalonia or Baltica plates abutting the TSZ. The LVZ appears to correspond to a hitherto unrecognized crustal segment (accretionary complex) that...article 2016

Physicochemical effects of discrete CO2-SO2 mixtures on injection and storage in a sandstone aquiferWaldmann, S. (author), Hofstee, C. (author), Koenen, M. (author), Loeve, D. (author)Geological storage of captured CO2, which typically will contain certain amounts of impurities, in salineaquifers is of potential to reduce greenhouse gas emissions into the atmosphere. The co-injection of theimpurity SO2has an effect on the chemical reactivity of the fluid and solid phases as well as on the physicalbehaviour of the CO2plume. To...article 2016

Roholl, J.A. (author), van Thienen-Visser, K. (author), Breunese, J.N. (author)In recent studies on the surface subsidence caused by hydrocarbon recovery of the Groningen gas field, the predicted subsidence is overestimated if results of compaction experiments are not corrected by an empirical `upscaling factor'. In order to find an explanation for this `upscaling factor', an analysis is presented of different laboratory...conference paper 2016

van Thienen-Visser, K. (author), Breunese, J.N. (author), Muntendam-Bos, A.G. (author)The Wadden Sea is a shallow tidal sea in the north of the Netherlands where gas production is ongoing since 1986. Due to the sensitive nature of this area, gas extraction induced subsidence must remain within the "effective subsidence capacity" for the two tidal basins (Pinkegat and Zoutkamperlaag) affected. We present a probabilistic method to...conference paper 2015
