Title (EN) ELECTRICALLY-CONDUCTIVE PROPPANT AND METHODS FOR MAKING AND USING SAME
(FR) AGENT DE SOUTÈNEMENT ÉLECTRO-CONDUCTEUR ET ET SES PROCÉDÉS DE FABRICATION ET D'UTILISATION
Abstract: front page image
(EN)Electrically-conductive sintered, substantially round and spherical particles and methods for producing such electrically-conductive sintered, substantially round and spherical particles from an alumina-containing raw material. Methods for using such electrically-conductive sintered, substantially round and spherical particles in hydraulic fracturing operations. A proppant pack comprising: a plurality of particles, each said particle, comprising a substantially uniform coating of an electrically-conductive metal having a thickness of at least 10 nm formed on the outer surface of each said particle, wherein each particle has a specific gravity of less than 4 and a size of about 80 mesh to about 10 mesh, wherein the pack has an electrical conductivity of at least about 5 S/m, and wherein increasing a load on the pack by a factor of 2 increases the electrical conductivity of the pack by at least 50%.
(FR)La présente invention concerne des particules frittées électroconductrices, sensiblement rondes et sphériques, et des procédés de production de ces particules frittées électroconductrices, sensiblement rondes et sphériques, à partir d'une matière première contenant de l'alumine. L'invention concerne également des procédés d'utilisation de ces particules frittées électroconductrices, sensiblement rondes et sphériques, dans des opérations de fracturation hydraulique.
