Fracture sealing by mineral precipitation: The role of small‐scale mineral heterogeneity
Geophysical Research Letters, 2016 Fractures are often leakage pathways for fluid in low‐permeability rocks that otherwise act as geologic barriers in the subsurface. Flow of fluids in chemical disequilibrium with fracture surfaces can lead to mineral precipitation and fracture sealing ...

Simulating Fracture Sealing by Granular LCM Particles in Geothermal Drilling
Energies, 2020 Lost circulation occurs when the returned fluid is less than what is pumped into the well due to loss of fluid to pores or fractures. A lost-circulation event is a common occurrence in a geothermal well.

The Sealing Mechanisms of a Fracture in Opalinus Clay as Revealed by in situ Synchrotron X-Ray Micro-Tomography [PDF]
Frontiers in Earth Science, 2020 The detailed mechanisms of the sealing of a single fracture, from hydration to almost complete closure by increase of confining pressure, as monitored from in situ synchrotron X-ray microtomography during the flow of carbonated water, is here shown for ...

A Novel Connectivity Metric of Identified Multi‐Cluster Fracture Networks in Permeable Formations
Geophysical Research LettersComplex natural fracture networks typically consist of multiple clusters, whose connectivity is rarely quantified. Therefore, for each identified fracture network, we propose a connectivity metric that accounts for individual fracture clusters and their ...
