Unsupervised Electrofacies Clustering Based on Parameterization of Petrophysical Properties: A Dynamic Programming Approach

François Fleuret, Karthigan Sinnathamby

Electrofacies using well logs play a vital role in reservoir characterization. Often, they are sorted into clusters according to the self-similarity of input logs and do not capture the known underlying physical process. In this paper, we propose an unsupe ...

Elongated hydraulic fracture emerging from layers of alternating fracture toughness

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo

Whether used to enhance the hydrocarbon production from low permeability rocks or to measure the minimum in-situ principal stress in rock formations, height growth of a hydraulic fracture above the formation of interest is a key metric for the design of su ...

Buoyant Hydraulic Fractures: How they Emerge, Grow, and get Arrested

Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo, Dmitriy Garagash

Most anthropogenic applications of hydraulic fracturing treatments are performed in sedimentary basins. In these geological formations, the minimum compressive stress is usually horizontal and increases with depth. As a result, hydraulic fractures grow alo ...

3D Geomechanical Modelling of a Potential CO2 Storage Site with focus on Fault Stability

Jean-François Molinari, Brice Tanguy Alphonse Lecampion, Guillaume Anciaux, Nicolas Richart, Emil Gallyamov

Underground CO2 storage represents the most viable Negative Emission Technology capable of significantly reducing atmospheric carbon dioxide levels. Ideal reservoirs for CO2 sequestration are thick highly-porous and highly-permeable formations ensuring a h ...

Birth and ascent of buoyant hydraulic fractures

Brice Tanguy Alphonse Lecampion, Andreas Möri

Hydraulic fracturing treatments are often used in petroleum and other industries to increase the permeability of rock formations and occur naturally as magmatic intrusions. The resulting fractures, propagating perpendicularly to the minimum in-situ stress ...

Can a bi-lateral stress jump really arrest the height growth of a hydraulic fracture?

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo, Barnaby Padraig Fryer

In certain industrial applications, vertical growth of hydraulic fractures beyond a targeted formation of interest can cause economic loss and pose a risk to environmentally sensitive layers [1]. In addition, when micro hydraulic fracturing is used to meas ...

Physical characterization of fault rocks within the Opalinus Clay formation

Marie Estelle Solange Violay, Christophe Nussbaum, Luis Felipe Orellana Espinoza

Near-surface disposal of radioactive waste in shales is a promising option to safeguard the population and environment. However, natural faults intersecting these geological formations can potentially affect the long-term isolation of the repositories. Thi ...
