Abstract
Methods comprising: injecting into a wellbore in a subterranean formation a multi-particle lost circulation material composition comprising a base fluid and a particle blend comprising substantially cylindrical particles and substantially spherical particles and wherein said particle blend comprises: degradable particles of at least three different sizes and wherein a first-sized particles and a second-sized particles are substantially cylindrical and a third-sized particles are substantially spherical.

A method comprising:
- injecting into a wellbore in a subterranean formation a multi-particle lost circulation material composition comprising:
- a base fluid and
- a degradable particle blend comprising substantially cylindrical particles and substantially spherical particles wherein the degradable particles are at least three different sizes and wherein a first-sized particles and a second-sized particles are substantially cylindrical and a third-sized particles are substantially spherical,
- wherein said first-sized particles are present in the degradable particle blend at about 60 wt. % to about 70 wt. %, by weight of the degradable particle blend, wherein said second-sized particles are present in the degradable particle blend at about 15 wt. % to about 30 wt. %, by weight of the degradable particle blend, and wherein said third-sized particles are present in the degradable particle blend at about 10 wt. % to about 20 wt. %, by weight of the degradable particle blend;
- and
- wherein said wellbore comprises at least one opening that causes at least some lost circulation that at its largest width is from about 7 mm to about 15 mm and wherein the degradable particle blend is used to seal or reduce lost circulation in the at least one opening.
