Evolution of water content and suction of Opalinus Clay from recovery at the drilling site to handling in the laboratory
Lyesse Laloui, Alessio Ferrari, Angelica Tuttolomondo
Advanced geotechnical engineering applications, such as shale gas extraction, CO2 geological sequestration, and geological radioactive waste storage, often involve various types of shales located at significant depths. Shales exhibit mechanical properties ...
Oxford2024Re-evaluating the mythical divide between traditional and novel cardiovascular risk factors in rheumatoid arthritis
Cardiovascular (CV) risk factors for rheumatoid arthritis (RA) are conventionally classified as 'traditional' and 'novel'. We argue that this classification is obsolete and potentially counterproductive. Further, we discuss problems with the common practic ...
London2024Modeling of solids particle diversion to promote uniform growth of multiple hydraulic fractures
Solid particulate additives are sometimes used to promote the uniform growth of multiple hydraulic fractures in horizontal oil and gas wells. The principle is that solid particulates block, accumulate, and form larger porous plugging zones preferentially a ...
ELSEVIER2023Alpha-NML Universal Predictors
Michael Christoph Gastpar, Marco Bondaschi
Inspired by Sibson’s alpha-mutual information, we introduce a new parametric class of universal predictors. This class interpolates two well-known predictors, the mixture estimator, that includes the Laplace and the Krichevsky-Trofimov predictors, and the ...
2022Improving the Accuracy of Fracture Toughness Measurement in Burst Experiments
Experimental studies suggest that the fracture toughness of rocks increases with the confining pressure. Among many methods to quantify this dependency, a so-called burst experiment (Abou-Sayed, 1978) may be the most widely applied in practice. Its thick w ...
SPRINGER WIEN2022Microbial-induced carbonate precipitation applicability with the methane hydrate-bearing layer microbe
Production of methane gas from the methane-hydrate-bearing layer below the deep-ocean floor is expected to be crucial in the future of energy resources worldwide. During the methane gas-production phase from the methane hydrate with the depressurisation me ...
ELSEVIER SCI LTD2020Fiber Bragg grating-based thermometer for drill bit temperature monitoring
The temperature measurement of a drill bit during an implantology drilling process is proposed by using a fiber Bragg grating fitted inside the drill bit. Due to the rotational nature of the drilling process, a free-space fiber-optic rotary joint is used f ...
