Lost-circulation material made from inorganic, recycled roofing materials

Abstract

A method of treating a portion of a subterranean formation can include introducing a treatment fluid into the portion of the subterranean formation. The treatment fluid can be a drilling fluid, a spacer fluid, a cement composition, or a stimulation fluid. The treatment fluid can include a base fluid; and a lost-circulation material (LCM), wherein the LCM comprises a plurality of particles of inorganic components of roofing materials, wherein the plurality of particles has a particle size distribution (PSD), and wherein the d99 particle size is in a range of 25 to 35 times greater than the d10 particle size; and allowing the LCM to reduce loss of the base fluid into the subterranean formation. The particles of the LCM can include solid aggregates of a combination of different minerals. The PSD and concentration of the LCM can be selected to provide a targeted fluid loss control.
