Abstract

See full text

An angular abrasive proppant comprises angular sintered particles of a material selected from bauxite, clay-minerals, and mixtures thereof, with particle sizes varying from 30 mesh to 150 mesh. A process for the production of an angular abrasive proppant comprising sintered particles of a material selected from bauxite, clay-minerals, and mixtures thereof comprises the steps of drying, grinding, pelletizing, and sintering a bauxite starting material, grinding the sintered pellets, and sizing said particles to a particle size varying from 35 to 150 mesh. A hydraulic fracturing process uses as proppant the angular abrasive proppant as the described above.
