Stormflow Response and “Effective” Hydraulic Conductivity of a Degraded Tropical Imperata Grassland Catchment as Evaluated With Two Infiltration Models

Cheng, Z. (author), Zhang, J. (author), Yu, B. (author), Chappell, N.A. (author), van Meerveld, H.J. (author), Bruijnzeel, L.A. (author)

Predicting catchment stormflow responses after tropical deforestation remains difficult. We used 5-min rainfall and storm runoff data for 30 events to calibrate the Green-Ampt (GA) and the Spatially Variable Infiltration (SVI) models and predict runoff responses for a small, degraded grassland catchment on Leyte Island (the Philippines), where...

Estimating hydraulic conductivity correlation lengths of an aquitard by inverse geostatistical modelling of a pumping test

van Leer, M.D. (author), Zaadnoordijk, W.J. (author), Zech, A. (author), Griffioen, J. (author), Bierkens, M.F.P. (author)

Aquitards are common hydrogeological features in the subsurface. Typically, pumping tests are used to parameterize the hydraulic conductivity of heterogeneous aquitards. However, they do not take spatial variability and uncertainty into account. Alternatively, core-scale measurements of hydraulic conductivity are used in geostatistical upscaling...

Bayesian networks applied to ESP performance monitoring and forecasting

Dussi, S. (author), Octaviano, R. (author), Shoeibi Omrani, P.S. (author)

Predicting the degradation of the Electrical Submersible Pumps (ESP) performance well in advance to avoid its failure is a rewarding yet challenging task. The complex interdependencies with well-reservoir properties and between machine components influence ESP performance and ultimately can lead to different types of failure. Predictions based...

A study on the hydraulic aperture of microannuli at the casing–cement interface using a large-scale laboratory setup

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...

Physical controls and a priori estimation of raising land surface elevation across the southwestern Bangladesh delta using tidal river management

Islam, M.F. (author), Schot, P.P. (author), Dekker, S.C. (author), Griffioen, J. (author), Middelkoop, H. (author)

The Ganges–Brahmaputra–Meghna delta in Bangladesh is one of the largest and most densely popu lated deltas in the world and is threatened by relative sea level rise (RSLR). Renewed sediment deposition through tidal river management (TRM), a controlled flooding with dike breach, inside the lowest parts of the delta polders (so called beels) can...

Temporal and spatial variability of cross-fault groundwater-level differences: the impact of fault-induced permeability reduction, precipitation and evapotranspiration

Lapperre, R.E. (author), Bense, V.F. (author), Kasse, C. (author), van Balen, R.T. (author)

Faults in the Roer Valley Rift System (Netherlands, Belgium, and Germany) act as barriers to lateral groundwater flow in unconsolidated sedimentary aquifers. This causes a cross-fault groundwater-level step of up to several metres. Using a dataset obtained through 5 years of high-frequency monitoring, the effect of fault-zone permeability,...

Effects of fault transmissivity on the potential of fault reactivation and induced seismicity: Implications for understanding induced seismicity at Pohang EGS

Wassing, B.B.T. (author), Gan, Q. (author), Candela, T. (author), Fokker, P.A. (author)

Enhanced Geothermal Systems (EGS) involve hydraulic stimulation of the permeability of deep low-permeable rock formations. This causes the reactivation and opening of pre-existing natural fracture networks and the formation of new fractures. During hydraulic stimulation, injection pressures at the bottom of the injection well can reach...

A system approach for replacement strategy of hydraulic structures

van der Wiel, W.D. (author), Klanker, G. (author), Klerk, W.J. (author), Persoon, E. (author), Wessels, J. (author), de Wit, A. (author)

Many of the Dutch movable hydraulic structures are exceeding lifetime expectancy based on the then-current standards and regulations. Also signs of ageing become apparent, regulations (e.g. about structural safety) get more and more strict and functional requirements have often increased over time due to climate change and socio-economic...

A review of numerical simulation strategies for hydraulic fracturing, natural fracture reactivation and induced microseismicity prediction

Shahid, A.S.A. (author), Fokker, P.A. (author), Rocca, V. (author)

Hydraulic fracturing, natural fracture reactivation and resulting induced microseismicity are interconnected phenomena involved in shale gas exploitation. Due to their multi-physics and their complexity, deep understanding of these phenomena as well as their mutual interaction require the adoption of coupled mechanical and fluid flow approaches....

Natural-Fracture Reactivation in Shale Gas Reservoir and Resulting Microseismicity

Shahid, A.S.A. (author), Wassing, B.B.T. (author), Fokker, P.A. (author), Verga, F. (author)

A geomechanical and fluid-flow coupled model was developed to simulate natural-fracture-network reactivation during hydraulicfracturing treatments in shale gas reservoirs. The fractures were modelled using the continuum approach in a commercial finitedifference code, labeled the "softening ubiquitous joints" model, with randomly distributed...

Calibrating a large-extent high-resolution coupled groundwater-land surface model using soil moisture and discharge data

Sutanudjaja, E.H. (author), van Beek, L.P.H. (author), de Jong, S.M. (author), van Geer, F.C. (author), Bierkens, M.F.P. (author)

We explore the possibility of using remotely sensed soil moisture data and in situ discharge observations to calibrate a large-extent hydrological model. The model used is PCR-GLOBWB-MOD, which is a physically based and fully coupled groundwater-land surface model operating at a daily basis and having a resolution of 30 arc sec (about 1 km at...

Addressing uncertainties in estimates of recoverable gas for underexplored Shale gas Basins

ter Heege, J.H. (author), Zijp, M.H.A.A. (author), de Bruin, G. (author), ten Veen, J.H. (author)

Uncertainties in upfront predictions of hydraulic fracturing and gas production of underexplored shale gas targets are important as often large potential resources are deduced based on limited available data. In this paper, uncertainties are quantified by using normal distributions of different input parameters in wellbased models for hydraulic...

ten Veen, J.H. (author), Verreussel, R.M.C.H. (author), Ventra, D. (author), Zijp, M.H.A.A. (author)

Shale gas reservoir stimulation procedures (e.g. hydraulic fracturing) require upfront prediction and planning that should be supported by a comprehensive reservoir characterization. Therefore, understanding shale depositional processes and associated vertical and lateral sedimentological variability is key in predicting the character and...

Upfront predictions of hydraulic fracturing and gas production in underexplored shale gas basins: Example of the posidonia shale formation in the Netherlands

TerHeege, J.H. (author), Zijp, M. (author), DeBruin, G. (author), Buijze, L. (author)

Upfront predictions of hydraulic fracturing and gas production of potential shale gas targets in Europe are important as often large potential resources are deduced without detailed knowledge on the potential for successful stimulation. Such predictions are challenging as they need to be based on limited available data, i.e. without well tests...

The success of shale gas exploration and production in the United States has triggered other countries around the world to look into possibilities of producing gas from different shales. As it turns out, one of the main difficulties when looking for shale gas is obtaining an in depth understanding of the shale formations and interpret where the...
