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.
Interaction of components within different phases and the fluid interaction with rock properties makes it difficult to accurately predict the natural flow...

Even though negative effects on the use of crude oil have surfaced over the past years, our energy matrix still largely relies on this energy source. The production of oil, therefore, plays an important role in our society. Unfortunately, the process of oil production is highly uncertain. There are uncertainties associated on the production...

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...

The subsurface of Groningen gas field composed of several faults. The continuous production has been resulting in several micro-seismicity activities, particularly for the past decades. One of the reasons for the production-induced-seismicity is fault reactivation at depth. The fault that initially in the non-active state becomes active and...

Coupling between porous media and free flow is widely present in many applications. In fractured reservoirs, fractures are often treated as parallel (smooth) plates, between which the flow is assumed to be steady state fully developed, with no-slip boundary condition. Under these assumptions, the Darcy law is employed inside fractures with...

Existing multiscale solvers use a sequence of aggressive restriction, coarse-grid correction and prolongation operators to handle low-frequency modes on the coarse grid. High-frequency errors are resolved by employing a smoother on the fine grid. Deflation preconditioning improves matrix properties, i.e., damps slowly varying errors,...

Modern geoscience challenges motivate the development of advanced simulation methods for large-scale geothermal fields, where single- or multi-phase flow is coupled with heat transfer equation in heterogeneous fractured formations. The state-of-the-art multiscale formulation for fractured media (F-AMS; Tene et al., JCP, 2016) develops an...

Designing strategies for efficient oil production from reservoirs rely heavily on reservoir simulation studies, which in-turn is based on various nonlinear formulations. It is therefore very important to develop a robust simulation model that captures the flow of various components present in different phases and the associated thermodynamic and...

The role of water storages at greenhouses will change in the future due to three trends in climate change, upscaling of greenhouses and changes in regulations. These three trends force the local water authority and the greenhouse sector to anticipate on future problems. First step in this process is to understand the hydrological response of...

One proposed method to delay the onset of gravity segregation between water and gas in enhanced oil and gas projects and extend the period of effective macroscopic sweep in “SWAG” is by separating the injection wells into two parallel horizontal wells (Stone, 2004). In this “modified SWAG”, the water injection well is aligned at a distance above...

Gas flow in fractured nano-porous shale formations is complicated by a hierarchy of structural features, ranging from nanopores to microseismic and hydraulic fractures, and by several transport mechanisms that differ from standard viscous flow used in reservoir modelling. In small pores, self-diffusion becomes more important than advection, also...

Reservoir simulation is a key tool to get insight in complex fluid flow phenomena occurring in many petroleum reservoirs, creating the possibility to quantify fluid productions and their uncertainty regarding many unknown properties. It has been shown by experimental and theoretical research that under certain criteria immiscible (multiphase)...

Production optimisation of a reservoir simulation problem can be very computationally demanding as the reservoir model may contain many variables and nonlinearities, thus many iterations may be needed to obtain an optimal production schedule. Using Proper Orthogonal Decomposition and Trajectory Piecewise Linearization (POD-TPWL) developed in [1]...

In this work, the non-linear behaviour of saturation transport equations in sequential implicit simulation strategy for multi-phase, immiscible and incompressible displacements are investigated. In reservoir simulation, use of explicit time schemes can lead to severe time-step size restrictions, specially when strong nonlinear terms exist. For...

Foam is a promising means of increasing sweep efficiency in enhanced oil recovery processes where gas is injected into a reservoir. However, the effectiveness of foam is hard to predict due to its complex behavior. Therefore accurate modeling is important to effectively predict field performance. This requires correct foam parameters in...

This thesis addresses the problem of permeability estimation of an oil reservoir using oil production data, a process known in the oil industry as computer-assisted history matching or data assimilation. Zilko (2012) compared the well-known Ensemble Kalman Filter method for data assimilation with the Non-Parametric Bayesian Beliefs Network (NPBN...

Algebraic Multigrid (AMG) is an efficient multigrid method for solving large problems, using only the information provided by the underlying matrices. Unfortunately, on a parallel machine the performance of AMG can be negatively affected by dense communication patterns. The exchange of extensive data sets is generally caused by a high number of...

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...

When an oil reservoir is underlain by an aquifer, oil production draws the water from the aquifer upward, forming a water cone, which under adverse conditions enters in the production well leading to high water cuts. An alternative option is to produce above the critical rate from the aquifer, i.e., at such a rate that the oil cone is drawn into...

Lately, the objective of reservoir engineering is to optimize hydrocarbon recovery from a reservoir. To achieve that goal, a good knowledge of the subsurface properties is crucial. The author is concerned with estimating one of the properties of the field: the permeability of a reservoir. To characterize the fluid flow, a two phase (oil-water)...
