METHODS AND COMPOSITIONS FOR PLACING PARTICULATE MATERIALS IN SUBTERRANEAN ZONES.

摘要

Methods and compositions for placing particulate materials in subterranean zones penetrated by well bores are provided. The methods basically comprise the following steps. A pumpable compacted particulate material fluid is prepared or provided comprising compacted particulate material and a foam within the pore spaces of the compacted particulate material. The foam comprises a pressurized gas and a liquid solution of a foam forming surfactant. After being prepared or provided, the compacted particulate material fluid is pumped into a subterranean zone by way of a well bore penetrating the zone.
