PROPPANTS COATED BY PIEZOELECTRIC OR MAGNETOSTRICTIVE MATERIALS, OR BY COMBINATIONS THEREOF |
摘要 |
<p>A method for tagging proppants so that they can be tracked and monitored in a downhole environment, based on the use of composite proppant compositions comprising a particulate substrate coated by a material whose electromagnetic properties change at a detectable level under a mechanical stress such as the closure stress of a fracture</p> |
