Simulation of stress dependent fluid flow in naturally fractured reservoirs
Naturally fractured reservoirs represent significant portion of the world's oil and gas reserves. In most of the reservoirs, fractures are important contributors to fluid flow. Thus, modeling and simulation of discrete fracture network is essential to assess responses of the reservoirs under …

Heavy Oil Recovery by Gas Assisted Gravity Drainage in Naturally Fractured Reservoirs
Most of the consolidated rock reservoirs are to some extent naturally fractured, but when the fractures do not affect the fluid flow, they are not taken in account and the reservoirs can be modelled as conventional reservoirs. However, in some reservoirs the fractures play a large role in the fluid …

Three-dimensional finite element modeling of two-phase fluid flow in deformable naturally fractured reservoirs.
The developed theoretical formulation and numerical model are validated against several cases where the analytical solutions or other model results are readily available. The performance of the numerical code is tested first by a couple of decoupled cases: elasticity and steady-state flow. The …

Simulating water tracer test in naturally fractured reservoirs using discrete fracture and dual porosity models
A naturally fractured reservoir (NFR) is a reservoir with a connected network of fractures created by natural processes such as diastrophism and volume shrinkage (Ordonez et al. 2001). There are two models to simulate this kind of reservoirs: the discrete fracture model and the dual porosity model. …

Field plot testing of EOR surfactant in dual-porosity naturally fractured reservoirs: single-well vs. multiple-well approach
Includes bibliographical references (pages 110-113).

Transient Shape Factors for Thermal Flow Simulation in Fractured Reservoirs
The simulation of naturally fractured reservoirs (NFRs) is an extremely daunting and challenging task. The most important and difficult aspect of modeling a naturally fractured reservoir is the accurate estimation of the fluid exchange between matrix and surrounded fractures, which is modeled via a …

Parametric and predictive analysis of horizontal well configurations for coalbed methane reservoirs in Appalachian Basin
… region to maximize methane recovery from coalbed reservoirs.;Horizontal wells are considered to be effective in the relatively thin, naturally fractured reservoirs that are characterized by permeability anisotropy. With today's advanced drilling technology, the direction of a horizontal wellbore …

Analytical solutions of pressure-production tests with permanent multisensors in oil gas and water zones
… presents approximations for both homogeneous and naturally fractured reservoirs and shows specialized graphs for the analysis of particular cases. Also, an analytical solution is developed to define the movement of the gas-oil contact. In this work, an approach to the study multiphase flow in the …

Evaluation of the performance of different polymer gel systems as an in-depth gel treatment using numerical simulation
<p>"Oil production from heterogeneous and naturally fractured reservoirs are usually hindered due to the presence of high-permeability streaks and natural fractures networks. Oil production could be more lowered if there is a crossflow from the high- to the low-permeability layers and high mobility …

Lattice-Boltzmann modeling of multiphase flow through rough heterogeneously wet fractures
… models, enhanced flow rate predictions for naturally fractured reservoirs can be obtained.

Optimization of chemical enhanced oil recovery methods for naturally fractured carbonate reservoirs
Carbonate oil reservoirs are important energy sources, accounting for over 60% of the world’s oil reserves. Recovering oil from these reservoirs is challenging, especially if they are naturally fractured. Waterflooding is inefficient because water flows through the highly permeable fractures and …

Simulation on Discrete Fracture Network Using Flexible Voronoi Gridding
Fractured reservoirs are generally simulated using Warren and Root26 dual-porosity (DP) approach. The main assumption of this approach is that the geometry of fractures are uniformly distributed and interconnected in reservoirs. This may be true for many cases of naturally fractured reservoirs. …

A Connectivity-based Hierarchical Model for Naturally Fractured Reservoir Simulation
Naturally fractured reservoirs usually contain multi-scale fractures with a wide range of fracture lengths and various topologies. Modeling of such fractured systems has traditionally followed a multi-scale approach, in which the selection of the numerical models is purely based on the fracture …

Geomechanically coupled modelling of fluid flow partitioning in fractured porous media.
Naturally fractured reservoirs are characterised with complex hydro-mechanical dynamics. In these reservoirs, hydrocarbons can be stored and produced from the rock matrix, the fracture network, or both. Normally the fracture network is depleted much faster than the matrix blocks due to its …
