Abrasion-resistant proppant composites and combinations thereof |
| abstract |
A hydraulic fracturing and gravel pack proppant composite having a protective agent on the proppant surface and a combination of the protective agent and the proppant. Surface protectants reduce the generation of dust/powder on the proppant caused by abrasion and impact during transport and transport, especially pneumatic transport. |
