A composite proppant having an increased buoyancy comprising a proppant substrate such as a porous ceramic or a silica sand coated with a material of a lesser actual density than the apparent density of the proppanl substrate to increase the buoyancy of the composite proppant.
L'invention concerne un agent de soutènement composite qui présente une flottabilité accrue. L'agent de soutènement selon l'invention comprend un substrat d'agent de soutènement tel qu'une céramique poreuse ou un sable siliceux enduit d'un matériau d'une densité réelle plus faible que la densité apparente du substrat d'agent de soutènement afin d'augmenter la flottabilité de l'agent de soutènement composite.
