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 …

Computational fluid dynamics modelling of fluid flow inside fractured reservoirs.
Fractured media exist in most layers of the earth's crust, often dominating bulk properties of subsurface geological formations. Therefore, fractured media are involved in many key engineering sectors that impact humans living on Earth. Fractured formations consist of two distinct media sharing the …

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 …

Mobility control of chemical EOR fluids using foam in highly fractured reservoirs
Highly fractured and vuggy oil reservoirs represent a challenge for enhanced oil recovery (EOR) methods. The fractured networks provide flow paths several orders of magnitude greater than the rock matrix. Common enhanced oil recovery methods, including gases or low viscosity liquids, are used to …

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 …

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. …

Numerical study of downhole heat exchanger concept in geothermal energy extraction from saturated and fractured reservoirs
… for mainly two types of geothermal reservoirs: saturated geothermal reservoirs and enhanced/engineered geothermal systems (EGS). Modeling of DHE is based on the concept of thermal resistance. A geothermal reservoir simulator is built reusing components of an existing blackoil …

Comprehensive evaluation of a novel EOR method-coupling low salinity water flooding and preformed particle gel to enhance oil recovery in fractured reservoirs
… economic and environmental problem as more reservoirs are maturing. Water channeling, one of the primary reservoir conformance problems, is caused by reservoir heterogeneities that lead to the development of high-permeability streaks. The recovery of oil from carbonate reservoirs is usually …

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 …

Efficient algorithms for flow models coupled with geomechanics for porous media applications
… especially in the case of stress-sensitive and fractured reservoirs. Considering that fractures are very much prevalent in the porous media and they have strong influence on the flow profiles, it is important to study coupled geomechanics and flow problems in fractured reservoirs. In this work, …

Evaluation of the performance of different polymer gel systems as an in-depth gel treatment using numerical simulation
… 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 …

Fracture Modeling and Flow Behavior in Shale Gas Reservoirs Using Discrete Fracture Networks
Fluid flow process in fractured reservoirs is controlled primarily by the connectivity of fractures. The presence of fractures in these reservoirs significantly affects the mechanism of fluid flow. They have led to problems in the reservoir which results in early water breakthroughs, reduced …
