A method is provided for treating at least a portion of a subterranean formation. The method includes introducing a treatment fluid including a composite particle, which includes proppant incorporated into or attached to a swellable material and/or swellable materials, into a subterranean formation via a wellbore; and increasing the buoyancy of the composite particle including proppant by either mixing it with a treatment fluid or mixing it with a treatment fluid and triggering the swellable material and/or swellable materials to swell. L'invention concerne un procédé de traitement d'au moins une partie d'une formation souterraine. Le procédé comprend l'introduction d'un fluide de traitement comprenant une particule composite, qui comprend un agent de soutènement incorporé dans ou fixé à un matériau dilatable et/ou des matériaux dilatables, dans une formation souterraine par l'intermédiaire d'un puits de forage ; et l'augmentation de la flottabilité de la particule composite comprenant l'agent de soutènement ou en la mélangeant avec un fluide de traitement ou en la mélangeant avec un fluide de traitement et en déclenchant le gonflement du matériau dilatable et/ou des matériaux dilatables.
