Sulfate performance of calcined illitic shales
(Elsevier, 2021-07)
In the past, calcined pozzolans were largely used in massive concrete, and nowadays, they appear as an excellent alternative to reduce the clinker factor in general use cement. The pozzolanic activity of two calcined illitic ...
Functional characterization on colloidal suspensions containing xanthan gum (XGD) and polyanionic cellulose (PAC) used in drilling fluids for a shale formation
(Elsevier Science, 2017-12)
Drilling fluids are employed in the operation of hydrocarbon exploitation. Two kinds of drilling fluids are commonly used: water based muds and oil based muds. The oil based muds are characterized by their high performance ...

Diffusion-reaction studies in low permeability shale using X-ray radiography with cesium
(Elsevier, 2013-12)
An X-ray radiography method for the determination of diffusion coefficients in rock has been modified to provide an estimation of diffusion-reaction parameters for the sorbing tracer, cesium (Cs+ ). Cesium tracer diffusion ...
Evaluación técnico-financiera a nivel laboratorio de un fluido de perforación de alto desempeño base agua para la perforación de la sección intermedia de un pozo del campo Castilla
(Fundación Universidad de América, 2017-11-07)
El presente trabajo se realiza con el objetivo de diseñar un fluido de perforación base agua de alto desempeño con la capacidad de inhibir las lulitas reactivas presentes durante la perforación de la sección intermedia (12 ...
A combined rock-magnetic and EPR study about the effects of hydrocarbon-related diagenesis on the magnetic signature of oil shales (Vaca Muerta formation, southwestern Argentina)
(Elsevier Science, 2019-02)
A combined study of rock-magnetism and electronic-paramagnetic resonance (EPR) was performed in core samples from an oil well in the Vaca Muerta Formation (SW Argentina). The aim of this work was to characterize the effects ...
Calcined illite-chlorite shale as supplementary cementing material: Thermal treatment, grinding, color and pozzolanic activity
(Elsevier Science, 2019-10)
The thermal transformation (100–1100 °C) of two shales containing illite-chlorite (I/Ch), feldspars and quartz from La Cabañita quarry (Olavarria, Argentine) was studied by TG-DTA, XRD and FTIR. It included dehydration; ...
Contrasting Mechanical and Hydraulic Properties of Wet and Dry Fault Zones in a Proposed Shale-Hosted Nuclear Waste Repository
(Blackwell Publishing Ltd, 2019)
©2019. American Geophysical Union. All Rights Reserved. The underground disposal of high-level nuclear waste is a pressing issue for several countries. In Switzerland, the Opalinus Clay formation is a shale with favorable ...
