Lightweight particulate materials and uses therefor |
| abstract |
Methods and compositions useful for sand control and/or hydraulic fracturing of subterranean formations that utilize relatively lightweight and/or substantially neutrally buoyant particles as particulate sand control or proppant material. Particles that may be employed include particulates of naturally-occurring materials that may be optionally strengthened or hardened by exposure to a modifying agent. Effectiveness of a modifying agent may be optionally enhanced by facilitating interaction between a modifying agent and one or more components present in a naturally occurring material by using enhancing agents and/or by using conditions that enhance interaction. |
