The application of Nano-silica gel in sealing well micro-annuli and cement channeling [PDF]
arXiv, 2023 The possibility for hydrocarbon fluids to migrate through debonded micro-annuli wells is a major concern in the petroleum industry. With effective permeability of 0.1-1.0 mD, the existence of channels in a cement annulus with apertures of 10-300 micrometer constitutes a major threat. Squeeze cement is typically difficult to repair channels-leakage with

Anomaly Detection Method for Hybrid Workpieces Using Dynamic Time Warping
Advanced Engineering Materials, EarlyView.Monitoring of hybrid workpieces: when machining hybrid workpieces, unavoidable axial deviations of the material transition zone cause temporal shifts in the process force signals. A new anomaly detection method based on dynamic time warping is proposed to detect material defects.

Micromechanics analysis of thermal expansion and thermal pressurization of a hardened cement paste [PDF]
Cement and Concrete Research (2011), 2011 The results of a macro-scale experimental study of the effect of heating on a fluid-saturated hardened cement paste are analysed using a multi-scale homogenization model. The analysis of the experimental results revealed that the thermal expansion coefficient of the cement paste pore fluid is anomalously higher than the one of pure bulk water.
