Abstract
A lost circulation material (LCM) that includes spheres having radially distributed and substantially-straight protrusions to facilitate engagement (such as interlocking and entanglement) of the spheres, and methods of preventing lost circulation using the spheres. Each sphere has a plurality of protrusions to contact protrusions of adjacent spheres. The spheres may form plugs in channels, fractures, and other openings in a lost circulation zone. Additionally or alternatively, the spheres may form a bridge on which other LCMs may accumulate to seal openings in a lost circulation zone.
