Overview of Piano Key weir prototypes and scientific model investigations

Anton Schleiss, Michael Pfister, Marcelo Leite Ribeiro

The interest in Piano Key weirs (PKW) was increasing over the past years, both in terms of application and hydraulic research. Several systematic model test series were per-formed and published so far, originating from different hydraulic laboratories arou ...

Self-Sealing of Localised Cracks in Boom and Opalinus Clay Hollow Cylinders

Laurent Gastaldo, Vincent Labiouse, Jean-François Mathier

The SELFRAC project aimed to study the fractures within the Excavation Damaged Zone (EDZ) around galleries in the Boom clay and Opalinus clay formations and their possible sealing/healing with time. Tests carried out at LMR-EPFL aimed at quantifying on the ...

Interface debonding as a controlling mechanism for loss of well integrity: Importance for CO2 injector wells

Brice Tanguy Alphonse Lecampion

The concept of CO2 storage relies on the long-term sealing properties of both the geological trap and the wells needed to inject and monitor CO2. Well integrity, a classical topic in the oil and gas industry, is thus critical for the performance of any CO2 ...

Hydraulic fracturing

Brice Tanguy Alphonse Lecampion

Method and apparatus for estimating a fluid driven fracture volume during hydraulic fracturing treatment of a ground formation. A series of tiltmeters are positioned at spaced apart tiltmeter stations at which tilt changes due to the hydraulic fracturing t ...

Micromechanical finite element modeling of compressive fracture in confined alumina ceramic

Jean-François Molinari, Derek Warner

A two-dimensional finite element model is developed to investigate intergranular fracture in alumina under compression. The grain interiors are modeled as anisottopic elastic and the properties of the grain boundaries are fitted from experimental data. Mat ...

Mapping of hydraulic fractures from tiltmeter measurements

Brice Tanguy Alphonse Lecampion

In considering the problem of inverse modeling of tiltmeter data for hydraulic fracture mapping, we address the issues of selecting the elastic model to represent the hydraulic fracture and limitations imposed by distance and fracture size on the informati ...

Heat slug propagation in QUELL. Part I: Experimental setup and 1-fluid GANDALF analysis

The experimental setup for heat slug propagation at zero current and field in the QUench Experiment on Long Length (QUELL) is described and re-evaluated. Eight inductively heated and four resistively heated runs are considered and analyzed with the 1-fluid ...
