Fractures are a primary factor controlling the fluid storage and transport properties of hydrocarbon reservoirs. The quantitative characterization of fractures in outcrop analogues allows a better understanding of natural fracture systems, to extrapolate predictive laws useful for integrating the limited data available for buried reservoirs....

Characterizing Dynamic Stress Sensitive Fracture Apertures in A DFN Representation: An Example From the Island of Pag (Croatia)

Prabhakaran, R. (author), Bruna, P.B.R. (author), Bertotti, G. (author), Mittempergher, S. (author), Succo, A. (author), Bistacchi, A. (author), Storti, F. (author), Meda, M. (author)

Improving the understanding of fluid flow through fracture networks is crucial to the optimum recovery of hydrocarbons in naturally fractured reservoirs. In explicit dual continuum representations of matrix and fractures, it is not just the intensity of fracturing and the topological relationships in the network but also connectivity of...

Are stylolites fluid-flow efficient features?

Bruna, P.B.R. (author), Lavenu, Arthur P.C. (author), Matonti, Christophe (author), Bertotti, G. (author)

It sounds counter-intuitive to consider contraction features such as stylolites as potential conduits for flow. However, this idea has grown since 1980, with geoscientists finding many examples principally in carbonate reservoirs where stylolites can be considered as fluid-efficient features. Among others, these features can be reactivated...

An automated fracture trace detection technique using the complex shearlet transform

Prabhakaran, R. (author), Bruna, P.B.R. (author), Bertotti, G. (author), Smeulders, D.M.J. (author)

Representing fractures explicitly using a discrete fracture network (DFN) approach is often necessary to model the complex physics that govern thermo-hydro-mechanical-chemical processes (THMC) in porous media. DFNs find applications in modelling geothermal heat recovery, hydrocarbon exploitation, and groundwater flow. It is advantageous to...

Geological and structural map of the southeastern Pag Island, Croatia: field constraints on the Cretaceous - Eocene evolution of the Dinarides foreland

Mittempergher, Silvia (author), Succo, Andrea (author), Bistacchi, Andrea (author), Storti, Fabrizio (author), Bruna, P.B.R. (author), Meda, Marco (author)

The sedimentary succession exposed in the Northern Dalmatia Islands mainly consists of Cretaceous to Neogene shallow water carbonates, folded and imbricated within the External Dinarides thrust belt. During Cretaceous times, carbonate sediments were deposed on a heterogeneous, tectonically-influenced carbonate platform, which was then uplifted...

A new methodology to train fracture network simulation using Multiple Point Statistics.

Bruna, P.B.R. (author), Straubhaar, Julien (author), Prabhakaran, R. (author), Bertotti, G. (author), Bisdom, Kevin (author), Mariéthoz, Grégoire (author), Meda, Marco (author)

Natural fracture network characteristics can be establishes from high-resolution outcrop images acquired from drone and photogrammetry. Such images might also be good analogues of subsurface naturally fractured reservoirs and can be used to make predictions of the fracture geometry and efficiency at depth. However, even when supplementing...

Natural fractures conduct fluids in subsurface reservoirs. Quick and realistic predictions of the fracture network organization and its fluid flow efficiency from limited amount of data is critical to optimize resources productivity. We recently developed a method based on multiple point statistics (MPS) technique to produce geologically...

A fracture flow permeability and stress dependency simulation applied to multi-reservoirs, multi-production scenarios analysis

The use of the subsurface and the exploitation of subsurface resources require prior knowledge of fluid flow through fracture networks. For nuclear waste disposal, for the enhancement of hydrocarbon recovery from a field, or the development of an enhanced geothermal system (EGS), it is fundamental to constrain the fractures and the fracture...

Understanding fractures and fracture networks is essential for the investigation and use of subsurface reservoirs. The aim is to predict the fractures and the fracture network when there is no direct access to subsurface images available. This article presents a universal workflow to numerically compute a discrete fracture network by combining...

The positive impact that natural fractures can have on geothermal heat production from low-permeability reservoirs has become increasingly recognised and proven by subsurface case studies. In this study, we assess the potential impact of natural fractures on heat extraction from the tight Lower Buntsandstein Subgroup targeted by the recently...

Vertical Movements and Petroleum System Modelling in the Southern Chotts Basin, Central Tunisia

The southern Chotts basin (SCB), Central Tunisia, has shown hydrocarbon potential since the end of the 1980s. This basin records a complex structural history which appears decoupled at the Hercynian or Variscan unconformity. The Paleozoic series is deformed by short to medium wavelength folds (kilometres-multi kilometres scale) and by steep...

Tutuarima, F.O. (author), Cecchetti, E. (author), Abels, H.A. (author), Bertotti, G. (author), Bruna, P.B.R. (author)

In this study, a re-evaluation is performed of the well data of the NLW-GT-01 and VAL-01 wells in the Lower Triassic sandstones in the West Netherlands Basin. Core, geophysical and image logs, are compared to document the characteristics of natural fractures distribution, and investigate the geological parameters influencing their development....
