Microporosity is commonly assumed to be non-connected porosity and not commonly studied in geoengineering industry. However, the presence of micropores plays a key role in connecting macropores and it can contribute significantly to the overall flow performance. In this study, targeted CO<sub>2</sub> storage carbonate fields in Southeast Asia...

In the community of petroleum engineering, the use of surrogate modelling techniques have recently gained more and more popularity to improve the efficiency of history matching. However, it is still not possible to fully utilize their potential in realistic applications. One of the challenges is to retain high accuracy while increasing the...

The main objective of this study is to perform Uncertainty Quantification (UQ) using a detailed representation of fractured reservoirs. This is achieved by creating a simplified representation of the fracture network while preserving the main characteristics of the high-fidelity model. We include information at different scales in the UQ...

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...

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...

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...

Ganapathy, Chandru (author)
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...

Many aspects of reservoir management can be expected to benefit from the application of computational optimization procedures. The focus of this review paper is on well control optimization, which entails the determination of well settings, such as flow rates or bottom hole pressures, that maximize a particular objective function. As is the case...

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...

The process of depleting an oil reservoir can be poured into an optimal control problem with the objective to maximize economic performance over the life of the ?eld. Despite its large potential, life-cycle optimization has not yet found its way into operational environments. The objective of this thesis is to improve operational applicability...

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...

Oil production optimization is one of the main concerns of the reservoir management. In this regard, optimal location of wells can lead to a significant increase in the oil production. The purpose of this research is to investigate a new extension of the automatic well-placement optimization technique maximizing the net present value (NPV) of...

The "Egg Model" is a synthetic reservoir model consisting of an ensemble of 101 relatively small three-dimensional realizations of a channelized reservoir produced under water flooding conditions with eight water injectors and four producers. It has been used in numerous publications to demonstrate a variety of aspects related to computer...
