Data-driven Discrete Well Affinity (DiWA) Model for Production Forecast: Optimization Performance and Model Enhancement

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...

Hind-casting Ungauged Reservoir Dynamics: A case study of the Kaluyo Basin in Bolivia

The construction of drinking-water reservoirs in previously free-flowing river basins introduces challenges in operational water management, especially in data scarce environments. Often resulting in effectively un- gauged basins. In order to be able to estimate the expected increase in water supply, the hydrology of the ungauged sub-basins must...

Adjoint-Based Optimization through Reduced-Order Subdomain Surrogate Modelling: An Application in Reservoir Simulation

Although a transition to more sustainable energy production is necessary, fossil fuels will remain a crucial contributor to the world's energy production in the near future. In numerically maximizing the production of these fuels, as well as in many other optimization problems, an objective function has to be optimized on the basis of an input...

Predictive Modelling of Hydrate Formation and Dissociation

Natural gas hydrates are often considered as a hazard in hydrocarbon production and pipeline transport, but are also recognized as a potential energy resource. Naturally occurring hydrate deposits exist under suitable conditions of low temperature and high pressure, typically in shallow marine sediments and in and below the permafrost, and may...

Tie-Simplex Parameterization of Operator Based Linearization for Isothermal Multiphase Compositional Flow In Porous Media

Compositional flow simulation is the best practise to model the complex enhanced oil recovery process. This involves solving highly coupled and non linear flow, transport equations.<br/>Interaction of components within different phases and the fluid interaction with rock properties makes it difficult to accurately predict the natural flow...

Parameterization of Element Balance Formulation in Reactive Compositional Flow and Transport

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...

Reservoir Simulation of Foam Flow using a Kepler GPU

In recent years, along with the higher GPU’s computational speed and memory bandwidth compared to those of CPUs, GPU-accelerated reservoir simulation has been studied quite extensively. The results so far have shown that Fermi generation GPUs could accelerate IMPES (implicit pressure explicit saturation) reservoir simulation considerably. Along...
