Petroleum resources continue to dominate the energy sectors with no sign of a decline. Petroleum reserves, however, are dwindling in view of fewer new discoveries and increased production level. It is important to determine petroleum reserves accurately in order to correctly forecast energy budget in the future.The most commonly used methods to describe the fluid flow in oil reservoirs employ constant rock properties. However, these methods are not applicable to reservoirs that undergo changes in the rock properties due to variation in pore pressure. Common characteristics of fractured reservoirs are sensitivity of permeability and porosity to effective stress. The in-situ stress, in itself, can be of mechanical or thermal origin. The thermal stress can be significant in thermal enhanced oil recovery schemes such as injection of cold fluid in hot formation during water flooding or wastewater disposal, or even during hydraulic fracturing.Unfortunately, the most commonly literature review reveals that the research in this area has been focused mainly on thermal recovery of heavy oil. Few investigation, however, have been done on the onset and propagation of fractures under thermal stress or mechanical stress. Consequently, this paper is devoted to investigate fracture development and propagation in carbonate formation under thermal and mechanical stress. A series of experiments were ingeniously designed to study the effect of thermal stress on fractured carbonate formation. Laboratory experiments were conducted to determine stress-strain relationship and the time dependence taking in account fracture formations and their propagation. A computer image analyzer was used to observe the fracture/fissures distribution for various cases of thermal stress on carbonate rocks. The role of thermal and mechanical stress in determining orientation and propagation of fractures was also studied.

“…This is in spite of the importance of the problem in a variety of environmental applications. Among the many possible examples, we mention here the geological storage of CO 2 in saline aquifers [9] in order to mitigate the effects of emissions on climate changes, and all processes involving the injection of a hot fluid into a cooler, fluid-saturated, subsurface rock including the socalled thermal Enhanced Oil Recovery [10]. All these applications have renewed the interest to understand RT-induced mixing in porous media [11][12][13][14][15].…”

Buoyancy-Driven Flow through a Bed of Solid Particles Produces a New Form of Rayleigh-Taylor Turbulence

et al. 2018

Rayleigh-Taylor fluid turbulence through a bed of rigid, finite-size, spheres is investigated by means of high-resolution Direct Numerical Simulations (DNS), fully coupling the fluid and the solid phase via a state-of-the art Immersed Boundary Method (IBM). The porous character of the medium reveals a totally different physics for the mixing process when compared to the wellknown phenomenology of classical RT mixing. For sufficiently small porosity, the growth-rate of the mixing layer is linear in time (instead of quadratical) and the velocity fluctuations tend to saturate to a constant value (instead of linearly growing). We propose an effective continuum model to fully explain these results where porosity originated by the finite-size spheres is parameterized by a friction coefficient.
