The increasing global demand for energy has necessitated the exploration of untapped potential energy resources. Unconventional oil reservoirs present a significant opportunity for development through various enhanced oil recovery (EOR) methods. Among these methods, the huff’n’puff scheme using Carbon Dioxide (CO2) EOR has emerged as a potent...

Compositional simulation is computationally intensive for high-fidelity models due to thermodynamic equilibrium relations and the coupling of flow, transport and mass transfer. In this report, two methods for accelerated compositional simulation are outlined and demonstrated for a gas vaporization problem. The first method uses a proxy model...

In this work, a novel globally implicit framework for reactive multiphase flow and transport has been implemented using the simulator DARTS and the geochemical package Reaktoro. This framework applies the Operator-Based Linearization (OBL) approach together with a Gibbs Energy Minimization (GEM) scheme to model complex nonlinear reactive...

Acidizing is a widely used technique for intensification of geothermal wells. At certain conditions, acid injection results in a formation of highly conductive channels, e.g. wormholes. The associated rock matrix dissolution is highly nonlinear and may influence the fluid flow as well as rock properties. Wormhole patterns and breakthrough time...

Evaluating an adequate computer model representing the characteristics of a subsurface reservoir is of great importance in the oil and gas industry. With recent data acquisition developments, high-resolution geological models can be generated for the subsurface reservoirs; however, uncertainties of geological data and too many details in the...

Carbon dioxide (CO2) capture and sequestration (CCS) can play a significant role in reducing anthropogenic CO2 emissions while allowing society to slowly phase out traditional energy sources. One of the main challenge in CCS is the current absence of a clear revenue model. One idea is to use the sequestered supercritical CO2 as a working fluid...

In this study, we introduce the Delft Advanced Research Terra Simulator (DARTS), which employs the Operator-Based Linearization (OBL) approach to provide efficient and precise solutions for non-linear discretized equations, to simulate the polymer flooding process. This compositional simulation framework is feasible for describing complex...

Energy transition extends the range of geological settings and physical processes to be taken into account in subsurface reservoir modelling. Many of these applications consider essentially anisotropic reservoir or require advanced gridding that can not be resolved consistently by conventionally used Two Point Flux Approximation (TPFA). In this...

The goal of this study is to test out the accuracy of the upscaling approach (Jinyu Tang, 2021) for a geothermal doublet. This approach tries to simulate the physical thermal dispersion. When modeling in a geothermal reservoir it would be easy if a lot of layers can be upscaled. However, when doing upscaling one can not just take an average of...

To produce accurate 3D fluvial architecture models, it is important to understand the influence of internally generated autogenic controls versus externally generated allogenic controls. When studying a fluvial system, autogenic controls such as river meandering and avulsions generally dominate over 103-104 years. Allogenic controls such as...

Transition to cleaner energy while sustaining the heat demand necessity has always been an emphasized topic in the recent years. With the slowly declining utilization and production of natural gas in Netherlands, geothermal energy shows a promising future in providing sustainable power for heating and various applications. For majority of...

Geological storage of COኼ is a crucial and upcoming technology to reduce anthropogenic greenhouse gas emissions. Due to the buoyant characteristic of injected gas, the security of underground storage is a major concern. To asses the security of COኼ storage, an accurate prediction of the gas plume behaviour is essential. In this study, a fully...

Before performing a field production forecast, an inverse problem has to be solved. Resulting in an ensemble of models that include the integration of real data with a complex physical and geological data describing subsurface processes. For large models, this approach can be very time and computationally expensive, therefore we propose an...

The hot water produced from a geothermal doublet possesses energy, which once utilized, the water cools down and is re-introduced back into the same reservoir at a sufficient distance using an injector well. As cold water flows through the reservoir, it acquires thermal energy from surrounding in-situ rocks. This process recurs until a...

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]<br/>In order to overcome this fast increase, the human...

We present a novel nonlinear formulation for modeling reactive-compositional flow and transport in presence of complex phase behavior due to combination of thermodynamic and chemical equilibrium in multi-phase systems. We apply this formulation to model precipitation/dissolution of minerals in reactive flow in subsurface reservoirs. The proposed...

In the modeling of fractured reservoirs, the spatial representation plays an important role to enclose the heterogeneities present in the subsurface. The reservoir flow response obtained from simulation in time is determined by the type of method and by the scale of the representation (fine or coarse). As a deterministic model cannot capture the...

Subsurface carbon dioxide (CO2) sequestration is a promising technology to reduce the CO2 emission into the atmosphere. After injection into subsurface formation, the carbon dioxide plume can migrate several kilometres until it is fully trapped. Four major mechanisms play an important role in trapping which include structural trapping, residual...

To date no efforts were published to (numerically) compute the pressure transients following shut-in for a fracture that during pumping was propagating at an arbitrary, not necessarily constant velocity; and to use these computations to systematically understand the physics (type curves) of pressure decline after shut-in for both very rapidly...
